2. The standard deviation as a measure of variability determines the extent to which performance in a test is homogenous or heterogeneous. A Math teacher wants to compare the performance of her students in the first quarter examinations in six different sections of grade 7 mathematics class. She selected two sections and found out that the standard deviations in the scores for the two sections A and B are 5.3 and 9.7, respectively.
