Our Dallas client was adamant that they “drew” from an enormous distance. And, in truth, they did however when you add it all up and look at the annual attendance for the year, the vast majority of attendance came from a 30 minute drive time.
The below map shows the attendance by zip code overlayed with drive-time zones of 30 minutes, 60 minutes and 90 minutes. The cost for purchasing mass-media, to reach the outer areas, was definitely not worth the return on investment!

If you’re new to GIS analysis, I recommend the following book as good intro.
Here’s a great book to get ideas on conveying data visually
RegEx to Clean Text
I used to work in Market Research and would spend hours cleaning up labels from surveys I’d programmed in online tools. The below video shows how easy it can be if you understand regular expressions and a little programming.
Regular Expressions can have a steep learning curve however it is really worth it if you continually get data that you need to clean. You can also check out this post of mine showing how they can be used to automate your metrics.
A handy cheat-sheet is downloadable from here and a wonderful course from Kevin Skoglund available from Lynda.com is available here. Below is a great intro to the Regular Expressions.
SPSS macro to remove characters from strings
While SPSS has many strengths, string manipulation is NOT one of them! Don’t get me wrong, you can manipulate strings however the syntax for doing so is very complex.
If you are still using an older version of SPSS, this macro shows how you can easily remove character(s) from a string both anywhere in the string or at a certain location. Newer versions have a Replace command which can be used to remove unwanted characters.

Creating customize SPSS toolbar buttons
I don’t know who set up the default toolbars but they clearly don’t work much in the “real world”!
The vast majority of work I do in SPSS is writing syntax however, having a frequency button or a button that empty’s the output screen is a lifesaver! Unfortunately most people don’t take the time to customize their toolbars.
This shows how easy it is to add – delete buttons from the toolbars. While the video shows the process on version 13 of SPSS, the same process works on newer versions.
