Stem and leaf plots aren’t used as widely these days as they were 30 years ago since it’s now just as easy to draw a histogram as it is to draw a stem and leaf plot. The values to the left of the . are called stems and the values to the right are called leaves.
Similarly, when we look at the line that reads 10 | 148, the way we interpret it to note that the stem and leaf plot is telling us that the data set contains observations with values 101, 104 and 108....Similarly, when we look at the line that reads 10 | 148, the way we interpret it to note that the stem and leaf plot is telling us that the data set contains observations with values 101, 104 and 108. If our data set had included only the numbers .11, .15, .23, .35 and .59 and we’d drawn a stem and leaf plot of these data, then R would move the decimal point: the stem values would be 1,2,3,4 and 5, but R would tell you that the decimal point has moved to the left of the | symbol.
