jim_thompson5910Best ResponseYou've already chosen the best response.1
say you had 10.21,10.24, 10.29, 10.31, 10.52 The stems would be 102, 103, 105 The leaves would be 1, 4, 9 (for the stem 102), 1 (for the stem 103), and 2 (for the stem 105) So the stem and leaf plot would look like this 102  149 103  1 104  105  2 Key: 102  9 stands for the value 10.29

The rule is that each digit in the leaves column represents each data value, so that's why we have to force the rest of the number into the stem
