This is on its way … as promised … I will upload it later today or early tomorrow.
Someone asked this question in Quora and here is my answer which I think many of you will find useful:
If you use Excel on a Mac the chances are that you are not running Excel 2016 for the Mac and that your Mac does not have the ToolPak at all … I know, older versions have it and I know you can get alternatives!
In that case, I often demonstrate to Mac users how to create and automate the functions in the ToolPak: correlation matrix, regression analysis, moving averages, descriptive statistics … the others as well!
Descriptive statistics, for example, could be, for data in column A:
and so on.
Other answers have mentioned statistics software packages and that’s fine except they might not be free! Yes, if you are a student, your college or university is likely to have statistics software free for you to use.
How about R and R Studio, however? Open source, free, with massive amounts of support? Of course, it takes time to learn R but here is the code for some descriptive statistics using the psych package in R:
That’s it! This is what I get from my current data set, sales values: not exactly the same as the ToolPak but my point is, it is very easy to replicate. Look at the screenshot of the output from R.
By the way, as a novice or beginner level user of Excel, there is a lot to learn from manually automating what’s in the ToolPak. Moreover, if you take my next learning point, use this opportunity to set up templates for you to analyse your data sets: that means, you automate the ToolPak elements once and that is it!
Finally, many elements of the ToolPak return non volatile results which means that if you change your data, you have to run the ToolPak again. If you automate it yourself, the formulas you create will all be volatile: change the data, change the answers!

I have just completed another very successful Financial Modelling course and as you know, at the end of such courses, I come here and offer something new: a new topic, a new file or some advice. In this case, it is advice: things that you really need to think about when you create and work on any Excel file.
- Tab/Sheet Names
- Dead Cells 125,433 rows created but only 831 needed/active … files that balloon to many Mb for no real reason
Ever seen a tab name like this: FBU or OPT? I bet you have: short and sweet and probably mnemonic so easy to read and remember. How about L_P_Obasange_receivables_dont_forget_to PRINT_it_out? You think I am joking? I am serious! Just imagine you are working on your file with the large tab name and you want to link to a cell on that tab from another one: this is what will appear in your formula, by way of an example … =IFERROR(AND(A15=45,D26=”Jack”,L_P_Obasange_receivables_dont_forget_to PRINT_it_out!BA154 …
I am sure you see the point now. Keep tab names short and simple! More than that, if you do feel the need to use tabs to give instructions, colour code them to pass such messages: there are many colours to choose from so do that. Have a table of contents too. Give everyone a chance for a simple life!
If you share a file with someone, make sure any links in your file are either live or delete them. If you receive a file with links that you cannot use or update, you know how frustrating it is. Think of the user before you send linked files.
It is the easiest thing in the world to create a worksheet and as you work and improve what you are doing, to delete cells and ranges. We all do that. We create new ranges too, don’t we! Check your work now and again though and if these happen, take a break and check your file:
- it takes 30 seconds 45 seconds or even longer for the file to open
- what seems like a small file in terms of content and complexity has ballooned in size to 20 or 30 or more Mb
- saving the file takes an age too
If these things happen, go to a worksheet and press Ctrl+End and see where that takes you. You work only in the range A1: CD831 but Ctrl+End has taken you to CG125433 … what? How did that happen?
Even if there are not as many as an additional 1.8 million cells but just 500,000, look in those cells for formulas that are trying to find something from somewhere that is not there … in some of these extra cells for example. Delete all of these extra cells. I did that this week: an extra 1.8 million cells in TWO separate worksheets complete with formulas. File size down from 28 Mb to 0.8 Mb, opening time just seconds, recalculation time hardy noticeable.
They were just some of things to report on from this week. Otherwise, this group of delegates really enjoyed the work and their end of course presentations were interesting and showed that significant learning had taken place!

Are you interested in using BI? Do you already use it?
Did you know that BI is free to create?
I will be adding some BI resources here this week … but there are already some here! Take a look at Power Query and Power Pivot for a start.
Back soon and if there’s something you want me to write about, let me know.

A delegate asked me today if there was such a function as SUMDIVIDE. There isn’t of course, but I found a way to simulate it.
What would SUMDIVIDE do? SUMDIVIDE would have array 1 divided by array 2 and the results then added together: in the same way that SUMPRODUCT multiplies and then adds.
This is how it works: imagine A1:A5 contains array 1 and B1:B5 contains array 2 then the SUMPRODUCT function to divide them will be =SUMPRODUCT(A1:A5,1/B1:B5). Simple, eh? Who’d have thought it would be so simple.
