WebNotice that neither of the box plots have a symmetric distribution. The median and the IQR are appropriate choices for describing center and variability for these data sets. The middle half of the data displayed in the first box plot appear to be more spread apart, or show greater variability, than the middle half of the data displayed in the ... WebSymmetry: If the box is roughly symmetric around the median, it indicates a roughly symmetric data distribution. Spread: The length of the box represents the IQR, which indicates the spread of the data within the middle 50% of the distribution. Types of Box Plots. Box plots can be used for both univariate and multivariate data.

On this notes sheet, students are given information about box-and-whisker plots, specifically "The Five-Number Summary", including lower extreme/minimum, lower quartile/Q1, median/Q2, upper quartile/Q3, and upper extreme/maximum. Range and IQR are also included. WebA third possibility is that if, in a box plot, the box is split evenly on either side of the median and the whiskers are approximately the same length, the data is symmetric. Note We …
WebWhen working with box plots, the IQR is computed by subtracting the first quartile from the third quartile. In a standard normal distribution (with mean 0 and standard deviation 1), the first and third quartiles are located at -0 and +0 respectively. Thus …
