(Coefficient of variation) the score value is more than 15%. Based on the test scores,
Do participants have various abilities?
c. Participants are classified according to the following criteria:
Group I: if the score is less than the average value – (0.5 x IQR)
Group II: if the score is between average – (0.5 x IQR) to (average + (0.5 x IQR)
Group III: if the score is more than the average + (0.5 x IQR)
Count the frequency of participants from each group and visualize.
