Last week, Dick Kusleika and I conducted some training for the good folks at TD Ameritrade. While training, some of the folks found that Excel wasn't responding when double-clicking or right-clicking the mouse. As most of us know, there are plenty of shortcuts and productivity gains to be leveraged in Excel with the mouse. But these folks weren't able to do any of those mouse actions.
It turns out the issue was the Essbase Add-in. Essbase is the tool most finance departments use to easily port financial data into Excel. By default, Essbase highjacks the standard double-click and right-click for its own purposes. Essbase does this to give their users mouse-driven ways to perform some of the actions that are already in the Essbase menu.
If you're using the Essbase Add-in, you can reclaim the double-click and right-click mouse actions by going to the Essbase Options dialog box, then clicking on the Global tab. There, you will see the Mouse Actions section.
Uncheck the Enable Secondary Button option to reclaim Right-Click.
Uncheck the Enable Double-Clicking option to reclaim Double-Click.
At this point, all normal mouse actions will return to Excel.

Every so often, when working in Access, I get the ever delightful Huey Louie Dewey error message.
Never heard of it? Well, when you try to specify query criteria with commas and no operators or quotes, you get this error message:
The expression you entered contains invalid syntax, or you need to enclose your text data in quotes. You may have entered an invalid comma or omitted quotation marks. For example, if the Default Value property of a text field is ''Huey, Louie, and Dewey,'' it must be enclosed in quotes if you mean it as a literal text string. This avoids the confusion with the expression ''Huey Louie'' And ''Dewey''.
When I saw this error message today, I got to thinking » Read more: The Huey Louie Dewey Error Message Needs an Update

One of the first warnings an aspiring analyst hears is, "never take an average of an average". The reason for this warning may not be intuitive, but it's important to understand why it's generally a bad thing to average a bunch of averages. In today's post, I'll attempt to explain the problems with using simple averages and how Weighted Averages can help you avoid inaccurate conclusions about your data.
Where Straight Averages can Go Wrong
Imagine you manage two sales reps (Jim and Tim). These two sales reps have been working for you for three months. Over the last three months, you've collected data on their win rates vs. sales calls. After three months of selling » Read more: Understanding Weighted Averages

I've been pretty busy with client work, so no new blog post today. I did, however, want to share some updates I've made to my Dashboard Tools Add-In.
If you don't know yet, the Dashboard Tools Add-in is a utility that helps you: enhance your dashboards with stylized graphics, find viable color schemes, and create dashboard mock ups.
For this update, I added two new tools: a Color Capture tool and a Customize Percentages tool.
The Color Capture Tool
The new Color Capture tool is based on the eye dropper tool developed by » Read more: Dashboard Tools Add-In Update

Sentiment Analysis is a growing field in the world of BI and Data Science. With social media serving up millions of data points by way of comments, tweets, and status updates, it's becoming increasingly important to be able to take all that subjective text and turn it into quantitative data that can be integrated with other metrics. That is essentially what Sentiment Analysis is - a term that describes the exercise of quantifying subjective text by analyzing certain keywords deemed to be either positively or negatively charged.
How Sentiment Analysis Works
In its simplest form, a Sentiment Analysis algorithm can be nothing more than determining if a text string has more positive keywords than negative keywords. Text with more positive words is classified as positive content, while » Read more: Quantifying Subjective Text with an Excel-Based Sentiment Analysis Tool

Like many of you, I'm often asked to develop mockups (working demos of dashboards and reports).
In my zeal to make my mockup as realistic as possible, I spend a good bit of time generating sample data.
For example, if I'm mocking up an HR dashboard, I'll dedicate some brain power to generating salary data. Now in order to make salary data realistic, there has to be a believable mix of high salary and low salary records. I can't just use the RAND and RANDBETWEEN functions Excel provides. These functions generate random data in a "Uniform Distribution". That is to say, every number has an equal chance of occurring with an equal frequency.

I've covered these time-saving VBE (Visual Basic Editor) tricks across several posts over the years. I thought it would be helpful to get them all into a single post.
Whether you're a fresh-faced analyst new to programming, or a jaded veteran living on sunflower seeds and Mountain Dew, these tips will make programming with Excel and Access so much easier.
Tip 1: Block Comments
Are you still commenting code one line at a time?

I was recently asked to show some financial figures in significant digits. I'll be honest and say I've never had to do this in my many years of reporting, so I didn't exactly know what that meant. Apparently, the idea is when you're dealing with numbers in the millions, there is no need to inundate a report with superfluous numbers for the sake of showing precision down to the tens, hundreds and thousands place.
As an example, instead of showing the number 883,788, you could choose to round the number to one significant digit. This would mean displaying the same number as 900,000. Rounding 883,788 to two significant digits would show the number as 880,000.
