A given data set has: A mean of 26.5 An interquartile range of 5.5 A minimum of 21 And a maximum of 29 What measure describes all the values in the data set?

Mean

Step-by-step explanation:

Interquartile range- the interquartile range is simply the difference between the upper quartile and the lower quartile. It does not work for all values in the dataset so

It cannot be the answer.

The minimum is the minimum value in the dataset. It is the smallest in value. It does not work for all values in the dataset.

The maximum is the number with the highest value. It does not work for all the values in the dataset

Mean is correct, all the values in the dataset are used to calculate the mean value
