Answer:
Step-by-step explanation:
Given that the quiz scores for two different groups of math students are given below.
Group A =93, 90, 71, 77, 85, 75, 77, 85, 87, 90
Count =10: Mean = 83: Std dev: = 7.0852
Group B = 71, 75, 85, 95, 71, 71, 90, 95, 87, 80
Count =10: Mean = 82: Std dev: = 9.230
Since std dev is lower for group A
Group A has less variability and hence more consistent.
