B) confidence interval
C) p-value
D) median

Question

Quizplus · Accepted Answer

The interquartile range (IQR) is a measure of variability that is considered as midspread because it represents the range of values in the middle 50% of the data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of the data. Therefore, choice A is the best option for describing midspread. Confidence interval (B) and p-value (C) are not measures of variability, but rather statistical estimates used to assess the precision and significance of statistical results. The median (D) is a measure of central tendency that represents the midpoint of a set of values and is not specifically associated with variability.
