Step-by-step explanation:
Standard deviation is a measure of variability in a given set of data. It tells how far each value in the data is from the mean. A high standard deviation suggests that the values spread farther from the mean while a low standard deviation suggests that the values are very close to the mean.
Since Christian has a lower standard deviation, the variability of his scores is lower. Hence, the correct option is
B)The coach should choose Christian, because Christian is more consistent.
