Answer:C. Median and quartiles.

Step-by-step explanation:

Let's analyze the given data sets:

Data Set A: 1 1 3 5 0 0 41014

Data Set B: 2 1 4 5 1136531

Skewness:

Data Set A: This data set seems to be skewed right because it has a long tail of high values on the right side, especially with the large value of 41014.

Data Set B: This data set appears to be skewed left as it has a long tail of low values on the left side, especially with the large number of 1s.

So, for Data Set A, it's skewed right, and for Data Set B, it's skewed left.

Measures of Center and Spread for Data Set A:

Since Data Set A is skewed right, the best measures of center and spread to use would be:

A. Median and quartiles.

Measures of Center and Spread for Data Set B:

Since Data Set B is skewed left, the best measures of center and spread to use would be:

C. Median and quartiles.
