The Interquartile Range: Theory and Estimation.

Abstract

dc:description.abstract

<p>The interquartile range (IQR) is used to describe the spread of a distribution. In an introductory statistics course, the IQR might be introduced as simply the “range within which the middle half of the data points lie.” In other words, it is the distance between the two quartiles, <b><em>IQR</em> = <em>Q</em><sub>3</sub> - <em>Q</em><sub>1</sub></b>. We will compute the population IQR, the expected value, and the variance of the sample IQR for various continuous distributions. In addition, a bootstrap confidence interval for the population IQR will be evaluated.</p>
