WebMath with Mrs Stephens. 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. WebSimilarly, the lower whisker boundary of the box plot is the smallest data value that is within 1.5 IQR below the first quartile. Here, 1.5 IQR below the first quartile is 52.5 °F and the minimum is 57 °F. Therefore, the lower whisker is drawn at the value of the minimum, which is 57 °F. Example with outliers [ edit] Figure 6.

WebIn the Box-&-Whisker plot, IQR determines the width of the box. What is the 1.5 IQR rule? By multiplying the interquartile range with 1.5, you can determine the outliers of the dataset. Add IQR*1.5 to the third quartile, any number greater than the result is an outlier. WebApr 14, 2024 · Box and whisker plot (box median and interquartile range; whiskers from www.researchgate.net.

Those five numbers are: the minimum, first (lower) quartile, median, third (upper) quartile and maximum. Remember that we defined median in the lesson Mode and median and quartiles in the lesson Quantiles. Interpreting box and whisker plots WebA Box‑and‑Whisker plot (Tukey, 1977) is constructed as follows: a box is drawn from the 1 st to 3 rd quartile (the 25 th and 75 th percentiles); a horizontal line is drawn at the median (the 50 th percentile); the Interquartile range (IQR) is calculated: IQR = 3 rd − 1 st quartile an imaginary line is drawn at the 3 rd quartile + 1.5 × IQR; this is the Upper Inner fence how to stop an urgent message in teams
