Stemplots
How to make a stemplot:
1)Separate each observation into a stem, consisting
of all but the final (rightmost) digit, and a leaf, which is that remaining final digit. Stems may have as many digits as needed, but each leaf contains only a single digit.
2)Write the stems in a vertical column with the smallest value at the top, and draw a vertical line at the right of this column.
3)Write each leaf in the row to the right of its stem, in increasing order out from the stem.
