Work Step by Step
The advantage of the histogram against the stem-and-leaf plot is that by seeing the histogram, the shape of distribution can be identified easily, which is not possible in case of the stem-and-leaf plots. The disadvantage of the histogram over the stem-and-leaf plots is that the data is distributed in classes; therefore, the exact data point cannot be determined in the histogram but in the case of the stem-and-leaf plot, the exact data point can be determined from the plot.
