“Forgetful City”
A new memory enhancing technique is being tested on a random sample of townspeople to see if it improves their ability to recall facts. Ten people each in the age groups 20’s, 30’s, 40’s, 50’s and 60’s are included. The intervention involves a one-time group training seminar about the memory technique. Each participant then views a short video of “wiki facts” and is then assessed. The number of facts each person can remember is recorded for 5 consecutive days.

Explanation / Answer

A within-subjects variable is often referred to as a "repeated- measures variable"
Hence here the test scores on different days is the within subjects variable
