Question

What are the appropriate measures of center and variability to use with the data?

a) Mean and standard deviation.
b) Median and interquartile range.
c) Not specified.

Answer 1

The appropriate measures of center and variability to use with the data are mean and standard deviation, as well as median and interquartile range.

So, the correct answer is a) Mean and standard deviation.

Step-by-step explanation:

The appropriate measures of center and variability to use with the data are:

1. Mean and standard deviation - The mean gives the average value of the data set, while the standard deviation measures the spread or variability of the data around the mean.
2. Median and interquartile range - The median is the middle value of the data set, and the interquartile range measures the spread of the middle 50% of the data.

In summary, options (a) Mean and standard deviation and (b) Median and interquartile range are both appropriate measures of center and variability to use with the data.

So, the correct answer is a) Mean and standard deviation.
