Answer:
Mr Blake's science class
Step-by-step explanation:
The standard deviation is a measure of variation.
It tells us how far each of the data set in the distribution are far from the mean of the distribution.
The average score of students in Mr. Blake's science class was 73 with a standard deviation of 11, while the average score of students in Mrs. Arnold's class was 75 with a standard deviation of 10.
Since 11>10, Mr Blake's science class is more variable than Mrs. Arnold's class.
