In a study of height of koala bears, scientists found that the distribution was skewed left. However, in a study of height of polar bears, scientists found that the distribution was symmetric. What measure of centre and spread should the scientists use to describe their data?

Select one:

a. Nothing. Bears are scary.

b. The height of koalas bears should be described with mean and standard deviation. The height of polar bears should be described with median and IQR.

c. The height of koalas bears should be described with median and standard deviation. The height of polar bears should be described with mean and standard deviation.

d. The height of koalas bears should be described with median and IQR. The height of polar bears should be described with mean and standard deviation.

e. The height of koalas should be described with mean and variance. The height of polar bears should be described with median and standard deviation.

Solution

c. The height of koalas bears should be described with median and standard deviation. The height of polar bears should be described with mean and standard deviation.
