- Step 2: Identify the stems.
- Step 3: Draw a vertical line and list the stem numbers to the left of the line.
- Step 4: Fill in the leaves.
- Step 5: Sort the leaf data.
What are the disadvantages of a stem and leaf plot?
Disadvantages. A disadvantage of stem and leaf plots is they are really only useful for small data sets from about 15 to 150 data points. Dot plots are usually more useful for smaller data sets, and for larger data sets a box plot or histogram is used.
Why is a stem and leaf plot better than a histogram?
Similar to histogram it is used to compare the data. The stem and leaf plot has a slight difference over the histogram as it can be constructed more quickly and easily as compared to histograms. The stem-leaf plot shows individual data points whereas the histogram does not.
What is the key for stem-and-leaf plot?
