Data Analysis for Error Logs

Expert replies
by jwagner2718 » Wed Feb 04, 2015 3:06 pm
Hi everyone,

Not sure if this is the right place to put this, but I thought I might be able to help some of the studiers out there analyze their error logs. I work in a data analysis position for my full-time job and pivot and find trends in large chunks of data everyday. This past year I've been studying on my own for the GMAT and have been able to use some of the techniques I've learned on the job to find out where I needed to focus my studying the most and thought this might be something that is useful to others as well.

If you have an error log that you want analyzed, feel free to send me a message with your email and I'll reach out to you. Below are some examples of how I've moved around my own data hidden within my error log and I've also attached my error log so people can see the data set I'm working off of.

Thanks,
Jack

Here you can see that on my last Manhattan practice test I struggled the most on problem solving and on reading comprehension

In my last four practice tests, the most questions missed in the 600-700 difficulty zone were in the Algebra, Arithmetic, Consecutive Integers, and Percents categories

In my last four practice tests, I've gotten better at sentence correction and need to focus more on reading comprehension
