Lesson 2 - Text Processing Example

STOP THE VIDEO NOW... How you would solve this (very real!) problem? Load the Excel file and play around with some strategies. Only return to the video once you're convinced that you can't solve this -- you should spend at least 30 minutes trying to figure this out!

Strategy How would you "average" text responses… well, you can't. So, instead how about this: Convert each response to an equivalent number, e.g., Strongly Disagree = 1, Disagree = 2, and so on using a table lookup Calculate the average based on the numeric score Use a table lookup to find up the closest category to the numeric score, e.g., let's say the average comes out to 3.6 then you'd say the average was "Agree" as 3.6 is rounded up to 4 and 4 corresponds to "Agree" in our scale
