How does the stem and leaf plot appropriate for the statistics test procedure for assuming equal variance but difference in mean from two independent population test... HELP ME GUYS!!!

Solution

One purpose of a stem and leaf display is to clarify the shape of the distribution. So this is basically used for determining the normality of two independent population which is a basic assumption in testing statistical test procedure assuming equal variance but difference in mean from two independent population test. Also by placed back to back along a common column of stems we can check the varaibility and mean of the two sample
