A) set up a frequency distribution table and calculate the relative frequency for the following quiz scores that matt achieved in his algebra course:
matt’s quiz scores: 85, 88, 92, 71, 100, 78, 61, 61, 89, 99, 100, 65, 98, 85, 92, 79, 81, 85, 100, and 100.
use the following frequency intervals:
61 – 70
71 – 80
81 – 90
91 – 100
b) calculate the variance and standard deviation for matt’s quiz scores.
