Question

20 which of the following statements about range is true? there can be multiple ranges for a set of data. the range is a measure of variability the range is a measure of central tendency the range identifies the most commonly occurring number(s) in the set

Explanation:

1. Analyze each option:

• "There can be multiple ranges for a set of data": Range is calculated as maximum - minimum, so there's only one range for a data set. Eliminate this.
• "The range is a measure of variability": Range (max - min) shows how spread out data is, so it measures variability.
• "The range is a measure of central tendency": Central tendency (mean, median, mode) describes the center, range doesn't. Eliminate this.
• "The range identifies the most commonly occurring number(s)": Mode does that, not range. Eliminate this.

Answer:

The range is a measure of variability
