Here is a charting challenge to begin your Christmas week. Recently Guardian’s Data Blog released World Education Rankings data and a sample visualization (shown below).

Kaiser at Junk Charts took this data and suggested a few alternative visualizations [part 2]. (shown below).

While Kaiser‘s charts are probably more insightful, they also appear complicated to my layman eye.
Naturally I wanted to give this data a charting-shot and see what comes up.
But before I show you how I cooked my chart, I want to throw a challenge to you.
Your Homework – Make a chart from World Education Rankings data
- Download the original data from here (or from here).
- Make a chart (or few charts) visualizing the data.
- Your objective is make it easy for us to understand the World Education Rankings Data
- Upload your workbooks to Skydrive or some other public file sharing site.
- Share the URLs, images etc with us thru comments.
- Bask in glory!
How I visualized World Education Rankings Data
When I looked at the original data, I wanted to explore 2 things.
- How are the scores in reading, math & science are distributed? [Distribution]
- How does one country compare with another? [Comparison]
To keep it simple and compact, I made one chart that meets both these objectives.
Here is what I could come up with:

How is this chart constructed (Recipe)
- The chart is a scatter plot with scores for each area plotted with a different y value (reading = 1, maths = 2 and science = 3)
- The chart is also dynamic. Visit Excel Dynamic Charts page if you are new.
- The four selected countries and average are extra series in the chart with diff. formatting.
- The messages are constructed using RANK formula and concatenate operator &
- Other tricks used – incell dropdown boxes, text boxes with formulas, symbols, and chart formatting.
Since the process of making this chart is a bit more detailed, I made a youtube video explaining it. See it below.
Download the Excel Workbook
Click here to download the workbook. The file works best in Excel 2007 or above. Try the Excel 2003 version if you prefer.
Now your turn,
Go ahead and download the original data. Make your own visualization of World Education Rankings and post it using comments. I am waiting 🙂

Hi Purna..
Again a great tip.. Its a great way to convert Fractional Time..
By the way.. Excel has two great and rarely used formula..
=DOLLARFR(7.8,60) and =DOLLARDE(7.48,60)
basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...
This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12
Any ideas why?
@Jason
7.8 in Excel talk means 7.8 days
=7.8*24
=187.2 Hrs
=187 Hrs 12 Mins
If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day
Simple, assuming the fractional time is in cell A1,
Use below steps to convert it to hours & minutes:
1. In the target cell, write =A1/24
2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
3. Select Custom from “Number” tab and enter the code [h]:mm
4. Done!
Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'
good one
So how do I go the other way and get hours and minutes to fractional time?
If you have 7.5 in cell A1,
- Use int(A1) to get the hours.
- Use mod(A1,1)*60 to get minutes.
If you have 7:30 (formatted as time) in A1
- Use hours(a1) to get hours
- Use minutes(a1) to get minutes.
I had the same issue. You can solve it by changing the format as described above:
Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm
([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)
Thanks guys, these are the tips I'm looking for.
...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time
It doesnt work for greater than 24 hours
It returns 1:30 for 25.5 hours. It should have returned 25:30
Ideally I would right function as
=QUOTIENT(A1,1)&":"&MOD(A1,1)*60
Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.
Thanks very much, extremely useful !
