Here you will be shown a short example on how to read off the median value from a cumulative frequency curve. Finding the median of a histogram will require you to first add up the number of people involved.
Stem and leaf plots and measures of central tendency. If the histogram is skewed left the mean is less than the median. This histogram is not bell shaped so the center and spread are not a good summary of the data.
