When we have lots of data, we try to summarize it by calculating the average. As they say, averages are mean, they do not give away much.

I want to share with you an interesting example from Amazon.com on how they give more details by combining average with distribution.

As you might know, Amazon shows the rating of each of the products they sell. Customers & users rate the products from 1 to 5 stars. When you visit the product page you will see the average rating. But there is a small down-arrow next to it. When you click on it, Amazon shows you the break-up of that rating so you have a better idea of how the ratings are split.

Wow, what a weekend it has been. Indian cricket team has won Cricket world cup 2011. It has been a highly entertaining tournament and the finals were just incredible.

Congratulations to Team India for winning Cricket World-cup 2011.

I am tempted to make a dashboard of sorts to show the journey of Team India in this world cup. But I could not get much time to work on anything. I will post something this week to celebrate the victory.

During last one week, we had a gala time with Dashboard Week on chandoo.org. To wrap-up the week, I am sharing a list of recommended resources, websites, tutorials & ideas for making dashboards.

In 2008, I received an email from Robert Mundigl, which was the start of a life-long friendship. Robert asked me if he can teach us how to make KPI dashboards using Excel. I gladly said yes because I am always looking for new ways to use Excel.

The original KPI dashboards using Excel article was so popular. They still help around 12,000 people around the globe every month. Many of our regular readers and members have once started their journey on Chandoo.org from these articles.

In this article, we will revisit the dashboard and give it a fresh new spin using Excel 2007.

Purpose of the dashboard:

This is a guest article written by John for our Excel Dashboard Week.

This Dashboard was constructed for a number of reasons, one of which was to reduce the number of reports produced with the same data ( up to 6 separate files ). As we all know, when it comes to senior management and reports / files the more information they can get on one report / file the better for them. So, with this in mind I created the Dashboard to show the data they need to see “quickly” each week.

Early in Jan, I got this mail from Mara, a student in Excel School first batch.

Hi Chandoo,

I took your first Excel batch class and loved it. I created a dynamic and interactive dashboard for my work. My boss thinks it’s an excellent tool and I have you to thank for and also Francis Chin who shared his travel dynamic dashboard. I integrated things you taught so thanks so much!

I felt very proud reading her email, so I asked her if she can share the dashboard with some dummy data so that we all can learn from her example.

Being a lovely person Mara is, she gladly emailed me the workbook and I am thrilled to include it in Dashboard Week.

As part of Dashboard Week, in this post, we will take a look at Health-care Dashboard prepared and shared by Alberto. He put together an excellent dashboard to visualize hospital performance and understand what is going on. Read this post to understand how this dashboard is made, watch a tutorial video & download example workbook.

Thank you Alberto for sharing the file & helping us learn.

Hello there,

I am glad to announce this week (21-25 March, 2011) as Dashboard Week on Chandoo.org
What happens in Dashboard Week?
As you can guess, during this week, I will be posting exclusively about Excel Dashboards. This is the tentative agenda … []

There are beautiful, powerful & awesome charting examples all around us. Today, I want to show you how we can harness the power of Excel to create Analytical Charts.

Analytical What?!?

To be frank, I do not know what to call these charts, so I choose the term Analytical Charts. But this is what I have in mind when I say Analytical charts:

A chart is analytical chart,
(1) If it is interactive
(2) It it can answer different questions by re-structuring same data differently

Last Friday, we have learned about an interesting formula – IFERROR Formula using which you can easily handle errors in Excel workbooks.

Quite a few people reading that page asked, “Wow, this is good. But how can I take a sheet full of =IF(ISERROR(…)….) formulas and convert them to =IFERROR()”

There is a different set of folks who asked “Wow, this is good. But quite a few of my colleagues use Excel 2003 and they see a bunch of #NAME errors when I send them an excel workbook with IFERROR formulas. Any help?!?”

I am pleased to announce that I wrote 2 simple macros, iferror2iserror() and iserror2iferror() that would scan formulas in a bunch of selected cells and convert them from IFERROR to ISERROR and vice-a-versa.

If IFERROR() were to be a person, I would hug her so hard that Jo (my wife) would get in to a cat fight with her. I know many a woman (and man) who get in to a fight with Excel formulas often. But thankfully, we avoid that as IFERROR is not a real person. It is, however a darned useful formula.

Since I cannot hug a formula anymore than I can get my son to sit tight, I will go ahead and sing an ode to her, in my style – by writing about how useful and powerful IFERROR formula is.

We have a new series on chandoo.org. – Excel Challenges. From now, every 1-2 months, I will post an interesting Excel Challenge. These are tricky problems for which elegant solutions should be found. To keep the challenges exciting, we will have a small prize for a winner (if more people answer correctly, we pick one randomly)

Excel Challenge #1 – Find Overlaps in Machine Schedule Dates

We have an Excel Table, with the following data (snapshot above). You need to write formulas to display Ok or Not Ok in the adjacent column based on the following criteria:

1. Display Ok if the scheduling dates for that row do not overlap with remaining scheduling dates for that machine
2. Display Not Ok otherwise.

Here is a quick tip on removing data validation rules. We all know that data validation is a powerful feature in Excel to control what data is entered. But, sometimes, you may want to remove the rules from a set of cells. How would you do it? The normal approach is, Select the cells with […]

Many of us want to learn advanced Excel and make progress in our career. But how to do it? In this post, I show 3+1 ways in which you can learn advanced excel.

Last week I did an interview with Robert Mundigl of clearlyandsimply.com. Robert is an Excel wizard. You may know him thru the KPI Dashboard articles he has written on chandoo.org a while ago.

We spent about 90 minutes discussing some really cool & advanced Excel stuff. The interview will be available shortly on Excel School for our Dashboard students. But here is a snapshot of the dashboard we discussed in the interview. Robert taught me how to make such a dashboard using Excel.

Have you ever jumped back to normal view from print preview and noticed the annoying page break lines? They look distracting. They are like a naughty kid shouting for attention. look at me!!! How do we get rid of those lines after completing our business with print preview?!? Very simple. We just copy everything, press […]
