Which of the following statements is true regarding measures of variability?

• The range is calculated by subtracting the maximum value from the minimum value.

• The standard deviation measures the average distance of each data point from the mean.

• The range indicates how much values vary around the mean.

• The standard deviation is simply the difference between the highest and lowest values.

Which of the following statements about response rates is true?

• A response rate of 30% is considered excellent for survey reliability.
