Box and whisker plot interquartile range math. Statistics assumes that your values are clustered around some central value. A box and whisker plot is a way of compiling a set of data outlined on an interval scale. The iqr can be used as a measure of how spread out the values are. Range highest value lowest value.
So the interquartile range is the difference between the upper quartile and lower quartile. The interquartile range is 58 36 22 you can use a steam and leaf plot to find and display the median the lq and the uq. Firstly write the given data in. Since the centre spread and overall range are instantly apparent using these boxplots the arrangements can be matched easily.
Here is the stem and leaf plot that we made earlier in this section the median is at 22 22 2 22 and is marked by a box. So it s a measure of how big a set of values range from lowest to highest. Construct box and whisker plot. The range of a set of values is the highest value minus the lowest value in the set.
Draw the box plot for the given set of data. It is also utilised for descriptive data interpretation. The interquartile range abbreviated iqr is just the width of the box in the box and whisker plot.
