Artist 52 [7]

The statement that is most likely true is , The mean is less than the median because the data is skewed to the left.

Option  E is the correct answer.

<h3>What is a Box and Whisker Plot ?</h3>

The method of representing the variation in a data set is called a Box and Whisker Plot .

A data distribution in which the data is skewed to the left

the mean is less than the median.

A data distribution in which the data is skewed to the right

the mean of the data is greater than the median.

It is given in the question that

The distance from the minimum value to the first quartile is greater than the distance between the third quartile and the maximum value.

this means data is skewed to the left,

Therefore, the statement that is most likely true is , The mean is less than the median because the data is skewed to the left.

Option  E is the correct answer.

The complete question is

Indira makes a box-and-whisker plot of her data. She finds that the distance from the minimum value to the first

quartile is greater than the distance between the third quartile and the maximum value. Which is most likely true?

The mean is greater than the median because the data is skewed to the right.

The mean is greater than the median because the data is skewed to the left.

The mean is less than the median because the data is skewed to the right

The mean is less than the median because the data is skewed to the left.
