Let's Review:A stem and leaf plot is a great way to organize data by the frequency. It is a great visual that also includes the data. So if needed, you can just take a look to get an idea of the spread of the data or you can use the values to calculate the mean, median or ...
There are 7 values in the third row, and the cumulative count is now 16. The median is the fourth row, and its value is 130. The method of determining the median is discussed later. Example 3.7 Here is a stem-and-leaf plot to compare SBP (mmHg) readings of the following males and...
The first column contains cumulative counts. Reading these counts in a stem and leaf plot might not be intuitive at first. For each row, the counts sum that row and all rows further away from the median out to the distribution’s tail. ...
