One of the most dreaded courses during my under-graduation is Probability, Statistics & Queuing Theory. We called it PSQT. I struggled to understand the significance and concept of this course as I could barely concentrate in the class. We had a professor, who is probably a genius, but the moment he started the class, I would magically fall in to one of my after-noon naps. When I woke up, we are either in the middle of an elaborate t-test or going thru intricacies of a Markovian queue.

This was all 11 years ago. Later in life, I have embraced the world of probability & statistics. I still fear queues. May be I will get there one day. 😉

A good understanding of statistics & probability theory is necessary if you want to model complex real-life problems using Excel or similar tools. Naturally, Excel has several functions, features & supported add-ins to help you in this area.

Today, I want to share some of this with you. This article is broken down in to 3 parts.

  1. Learning Statistics & Probability using Excel
  2. Downloadable Excel Workbooks to understand
  3. Full blown models & simulations in Excel

#1 – Learning Statistics & Probability Concepts using Excel

Using Excel RAND functions

Excel has several powerful functions (formulas) to generate random numbers, random data. You can combine these functions to generate data that has certain parameters – like a give mean, standard deviation or follows a certain type of distribution.

Go thru Using Excel’s Random Functions for a detailed overview these techniques.

Simulating Dice Throws in Excel

One of the fundamental ways to learn about Probability is to look at dice throws. A dice has 6 faces and on each throw, any of the 6 faces turning up is equally likely. So, we say, each face has 1/6th probability of showing up. If you want to simulate this in Excel, you can use the formula RANDBETWEEN like this, =RANDBETWEEN(1,6). On each run, this formula would throw up a random number between 1 & 6 (including both).

Shuffling a List of Values in Excel

Understanding permutations and combinations is essential when it comes to modeling many real-world problems. Using Excel’s RAND, VLOOKUP and SMALL formulas we can generate a random permutation of a given list of values (in other words – we can shuffle the list).

Generate Frequency Distribution from Data

Often, when you are analyzing data, you need to understand how the data is distributed. Again, Excel has just the right function for this sort of thing. FREQUENCY(). In this simple tutorial, learn how to use Excel’s FREQUENCY formula to generate frequency distribution of given data.

Trend Analysis & Forecasting using Excel

One of the most common applications of statistics is trend analysis & forecasting. Again, Excel shines with a lot of powerful formulas, built-in features and charting tools to help you understand the data & predict future based on that.

Since this is a big topic, we have covered it in 3 parts –

Part 1- Introduction to Trend Analysis & Forecasting: In this, we will learn what is trend analysis & forecasting. We will see manual forecasting technique in Excel. We will use Excel charts to depict our analysis and results.

Trend Analysis & Forecasting using Manual Forecasting Technique in Excel

 

Part 2 – Trend Analysis & Forecasting using Excel Functions

In this second part, we learn about Excel’s functions like LINEST, TREND, FORECAST, SLOPE, INTERCEPT, LOGEST and GROWTH. These powerful formulas can process lots of data and extract the trend information dynamically.

 

Trend Analysis and Forecasting using Excel's functions & charts

 

Part 3 – Trend Analysis & Forecasting using Charts & Macros

In the final part, we talk about how to use Excel chart’s trend analysis & forecasting features to estimate the trend & predict future values based on the data.

Trend Analysis & Forecasting using Excel Charts & VBA

 

We also learn how to use Macros (VBA) to augment Excel chart’s trend-lines with useful information.

Visualizing Distribution of data with Box Plots

Box plots are an excellent way to understand the distribution of data. Unfortunately, there is no direct option to make a box plot from given data in Excel. That is where, this tutorial comes handy.

#3 Full blown models & simulations in Excel

A full blown model lets you learn various statistical concepts, Excel features and how to bring them all together to mimic a real-life situation.

Simulating Deal or No Deal game in Excel

In this simulation of Deal or No Deal, a popular television game, we use basic probability, permutations and Excel formulas features. You will learn how to assign random values to the suit-cases, how to use circular references, how to calculate the banker’s offer.

Generating Housie / Bingo Tickets in Excel

Housie (Bingo) is a popular recreational game where the tickets contain 15 numbers between 1 to 90, arranged in 10 columns (3×10 grid). First column has numbers between 1 to 9, second column has 10 to 19 so on..

Generating a bingo ticket in Excel is a nice exercise in statistics, permutations and Excel formulas.

Data Tables & Monte Carlo Simulations in Excel

Excel has powerful features to let us do complex simulations of real world situations. One such feature is called as data table.

The Data Table allows a set of what if questions to be posed and answered simply, and is useful in sensitivity analysis, variance analysis and even Monte Carlo (Stochastic) analysis of real life model within Excel.

The case of Blue Sky Mining Company

To help you learn about data tables, Monte Carlo simulations, we have put together a fictional mining company – Blue Sky co. and analyzed its performance under various assumptions & simulations.

Modeling & Scheduling a FIFO (First In First Out) Queue in Excel

FIFO queues are very common in life. You can see them at Airports, coffee shops, Apple stores; Except at Airports it is FIFOUYC (FIFO Unless You are Crew).

In this article, we model & schedule a FIFO queue using Excel.

Do you use Statistical Concepts for your work?

As a small business owner, a good portion of my work involves statistical analysis, forecasting and simulation. I run estimates for our website traffic, revenues. I run statistical tests (split tests etc.) to optimize our sales pages, website. I estimate when my kids wake up from their nap (based on past experience) and plan my work accordingly. Thankfully, for the last part, I do not use Excel 😀

What about you? Do you use statistical concepts for your work? What are the things you use and how does Excel help you in that? What are your favorite formulas, features and tips? Please share using comments.

    I tried your code with 2003, it works.

    But, I know Addpicture does not take URLs anymore with 2007 onwards, perhaps its the same with picture.insert as well.

    http://support.microsoft.com/kb/928983/en-us

    The above link gives the solution as "picture fill in a shape such as a rectangle".

  2. Vince E. says:

    Tried to recreate this, but it worked fine for me. I just took the image of the error you showed in the post. Is there more info that can narrow this down a bit?

  3. Ian Hinckley says:

    Hi

    Not sure if this is what you're after, but I just tried this

    Sub Macro1()
    ActiveSheet.Pictures.Insert("http://www.google.co.uk/intl/en_uk/images/logo.gif").Select
    End Sub

    Tied a button to it on the sheet and it seems to work; hope this helps a little

    Ian

  4. Chandoo says:

    @All.. the issue is in Excel 2007. In 2003 ActiveSheet.Pictures.Insert seems to work fine. Unfortunately, I have design this in Excel 2007.. that is why I posted it here..

  5. Ian Hinckley says:

    v2

    Sub Macro1()
    Set n = ActiveSheet.Pictures.Insert("http://www.google.co.uk/intl/en_uk/images/logo.gif")
    With Range("c12")
    t = .Top
    l = .Left
    End With
    With n
    .Top = t
    .Left = l
    End With
    End Sub

    Ian

  6. Ian Hinckley says:

    That didn't come out very well. This positions at c12, so can change easily:
    Sub Macro1()
    Set n = ActiveSheet.Pictures.Insert("http://www.google.co.uk/intl/en_uk/images/logo.gif")
    With Range("c12")
    t = .Top
    l = .Left
    End With
    With n
    .Top = t
    .Left = l
    End With
    End Sub

    Works OK in 2007

    Ian

  7. Chandoo:
    Try 'ActiveSheet.Pictures.Insert'

    With ActiveSheet.Pictures.Insert("C:\Example.png")
    .Left = ActiveSheet.Range("A1").Left
    .Top = ActiveSheet.Range("A1").Top
    End With

  8. Jon Peltier says:

    activesheet.pictures.insert "C:\Documents and Settings\Jon Peltier\Desktop\2007 stuff\insert_charts_2007.png"

    Works for me in 2003 SP3 and in 2007 SP2.

    Check the URL, and make sure you have internet connectivity.

    What also works, and is newer (pictures.insert was supposedly deprecated in '97):

    activesheet.shapes.addpicture "C:\Documents and Settings\Jon Peltier\Desktop\2007 stuff\insert_charts_2007.png", false, true, 200,200,100,100

    Unfortunately you must specify dimensions (the last four arguments) and you don't necessarily know them. But the picture size is still related back to the original picture size, so you could use scaleheight and scalewidth to fix this.

  9. Chandoo: I just re-read your post.

    The code I posted works for me. However, I'm using a local picture. If you try to add a picture from the web, this won't work.

    I remember solving this problem before by adding a rectangle shape first, then using the Shapes.AddPicture method to get a picture from the web.

    I'll find that code and post it here.

  10. Chandoo says:

    Some more updates... The code "ActiveSheet.Pictures.Insert (path)" works fine in Excel 2007 at home. Strange it failed miserably on my work laptop. Do you think this has got something to do with SP2 of MS Office 2007 or something like that?

    @Ian, Jon: Thanks for the code snippets. I guess I will use my home installation of excel to do this.

  11. Chandoo:

    Try this on your work laptop:

    Sub test()
    ActiveSheet.Shapes.AddShape msoShapeRectangle, 50, 50, 100, 200
    ActiveSheet.Shapes(1).Fill.UserPicture _
    "http://www.datapigtechnologies.com/images/dpwithPig6.png"
    End Sub

  12. Jon Peltier says:

    I didn't mean to post code with a local file, because both approaches worked with an internet image as well. This is in Excel 2007 SP2.

    activesheet.pictures.insert "http://peltiertech.com/images/2009-07/col_area_noblanks.png"

  13. Jon: Looks like I have SP1 on my client machine! I wasn't paying attention.

    Just checked my home computer where I have SP2, and you're right...looks like they fixed it.

  14. Jon Peltier says:

    I didn't even bother testing in SP1, though I could if anyone cares enough.

  15. teylyn says:

    I'm afraid I don't have a solution, but I find it remarkable that after attaining a certain status in the Excel world, Chandoo does not need to post on an Excel discussion forum to get help for an Excel problem. Instead, he posts on his blog and all the gurus come rushing to his help.

    Isn't Web 2.0 great?

  16. Jon Peltier says:

    Teylyn - I saw Chandoo's tweet first, and followed the link back to his blog.

  17. Chandoo says:

    @Mike.. thank you. I have seen the fill rectangle solution before posting the query here. For that matter, I have also tried the solution of embedding a browser control on a spreadsheet. both of these seemed a bit extreme. That is why I have asked it here.

    But I guess I will end up using it if I had to build this in work laptop.

    @Teylyn: I have thought of posting this in a forum. (Unfortunately I have not been to any excel group in the last 5 years. Last time I was active was when I built a jave based excel sheet construction solution using POI.HSSF classes of Apache... ) After searching for a few hours, I found several forum posts where others had same problem and the solution recommended (using .left and .top parameters) is not working for me. Incidentally most of these solutions are from a certain Jon Peltier 😛

    I thought may be the problem is interesting for fellow blog readers. So I posted it here.

  18. Justin B says:

    Hi,
    Adapting the code in the question,

    [code]
    Sub InsPicture()
    pPath = "http://chandoo.org/images/pointy-haired-dilbert-excel-charts-tips.png"
    With ActiveSheet.Pictures.Insert(pPath)
    .Left = Range("a1").Left
    .Top = Range("a1").Top
    End With
    End Sub
    [/code]

    Seems to work fine

  19. Jon Peltier says:

    Looks like it was a problem in 2007 up to SP1, which was corrected in SP2.

  20. Chandoo says:

    @Jon.. seems like the case. I just checked the version at work laptop. it is 12.0.6331.5000 (SP1).

    Thank you so much every one. I really appreciate your time and suggestions in solving this.

  21. Jon Peltier says:

    Glad to help. I couldn't understand why something so straightforward wasn't working.

  22. Kieranz says:

    Hi All
    Is there a way of inserting a motion clip eg animated gif or swf or flv?
    Thks

    • Chandoo says:

      You can insert animated GIFs by inserting them in a browser control through VBA. For other types of movies, I can guess you can insert them as clip art.

    I WANT THE INSERT PICTURE BY USING COADING

  24. Lutz says:

    so currently i was struggling same as you, chandoo, with the insert picture method in excel 2007/10 from an url and came along your thread here.

    so i re-designed the code on the addshape method as mike was suggesting it and all of the sudden it works just fine.

    thanks alot to you guys, you were a great help

    Hi guys,

    I need help copying and pasting an image with the path in a cell.
    I leave the code.

    And thank you very much!

    Sub Copiarimg()

    Dim pic As Picture

    With ActiveSheet

    Set pic = .Pictures.Insert(Range("f2").Value)

    With .Range("e9:g22")
    pic.Top = .Top
    pic.Left = .Left
    pic.Width = .Width
    pic.Height = .Height
    End With
    End Sub

  26. I've played around with the approaches in these comments, and the code below is what I've come up with. The ImagePath can be a local file or a URL. As Jon mentioned above, the trick is to set an arbitrary value for the width and height, then call the ScaleWidth and ScaleHeight methods afterward to reset the picture to its original size. Once the LockAspectRatio property is set, you can change the picture width and the height will automatically scale (or vice-versa).

    Sub AddPictureToRange(TopLeftCellAddress As String, ImagePath As String)

    Dim pic As Shape
    Dim l As Single, t As Single
    Dim temp As Single

    l = Me.Range(TopLeftCellAddress).Left
    t = Me.Range(TopLeftCellAddress).Top
    temp = 10# ' arbitrary value

    Set pic = Me.Shapes.AddPicture(ImagePath, msoFalse, msoTrue, l, t, temp, temp)
    pic.ScaleHeight 1#, msoTrue
    pic.ScaleWidth 1#, msoTrue
    pic.LockAspectRatio = msoTrue

    End Sub

  27. dip says:

    I need some help with inserting pictures. I have an excel file with a column of item numbers next to this row I want to insert a picture of this item. The pictures are coded with the item number so I tried to insert it with one of the codes above:

    Sub InsPicture()
    pPath = "http://img.bricklink.com/P/80/55236.gif"
    With ActiveSheet.Pictures.Insert(pPath)
    End With
    End Sub

    That worked but I need to do that for every row separtly.
    So I tried in the code
    pPath = "http://img.bricklink.com/P/80/"&Text(a1;"#")&".gif"

    But that gives errors.

    Anybody ideas?

    Hi,

    thanks all. In addition, I had a problem with multiple pictures inserting (every new picture replaced the prior one). I've changed it a bit, may be helpful..

      Thanks to everyone, this thread has been very helpful. However, image inserting still doesn't work quite as expect for me.

      While I can get a picture inserted into an Excel 2010 worksheet using either:

      1) ActiveSheet.Shapes(ActiveSheet.Shapes.Count).Fill.UserPicture...
      2) ActiveSheet.Pictures.Insert(pPath), and
      3) Shapes.AddPicture...

      unfortunately the images all insert with a display size determined not by the actual pixel dimensions of the image but by the dpi resolution.

      So for example, if I insert two copies of the exact same 600x600 pixel image, one with a 300dpi resolution and the other with 72dpi, they display at vastly different sizes on screen.

      While this might be intended behaviour for Excel in order to maintain a WSYWIG printing layout, I actually need a way to insert the image based on the the actual pixel dimesnsions and ignoring the dpi resolution.

      Any help appreciated.

      Thanks

  33. Kez says:

    Well, answered my own question 🙂

    For those who might be interested, you can use this function:

    Public Function GetPicDims(strFilePath As String, strFileName As String) As String
    GetPicDims = CreateObject("Shell.Application").Namespace((strFilePath)). _
    ParseName(strFileName).ExtendedProperty("Dimensions")
    End Function

    to get the dimensions of the image you want to insert. Then you can parse the return string and use the width and height values to add a rectangle shape of the appropraite size, like:

    ActiveSheet.Shapes.AddShape msoShapeRectangle 50, 50, iWidth, iHeight

    which you then fill with the picture:

    ActiveSheet.Shapes(ActiveSheet.Shapes.Count).Fill.UserPicture "c:\temp\test.jpg"

    This way the picture gets inserted using the pixel dimensions and the (print) resolution gets ignored.

    If desired, the GetPicDims function can be made more generic to get other ExtendedProperties.

    Regards
    Kez
