Question

1. A challenging mid term yields the following results: 18, 25, 25, 25, 32, 32, 35, 35, 35, 100. Which type of measure would best represent the center of the results and what is its value ?

Answer 1

Since, median is not affected by outliers or extreme numbers. In these scores 100 is high score than others so we should used median instead of mean to represent the center of the results.

Since the number of data values = 10 (even)

Mean = average of 5th and 6th value

Mean = (32 + 32)/2 = 64/2 = 32

Mean = 32
