Abby is collecting rainfall data. she finds that one value of the data set is a high-value outlier. which statement must be true?
a) abby will use a different formula for calculating the standard deviation.
b) the outlier will increase the standard deviation of the data set.
c) the spread of the graph of the data will not change.
d) abby will not use the mean when calculating the standard deviation.

Option: B is the correct answer.

B)  The outlier will increase the standard deviation of the data set.

Step-by-step explanation:

As the data set contain a high-value outlier this means that the mean of the data set will increase and also the spread of the data about the mean will increase and hence will result in the increase of the variance of the data set and hence standard deviation of the data set will increase.

Hence, option: B is the correct answer.
