Standard SDAP 1.1 – Know various forms of display for data sets, including stem-and-leaf plots, use the form to display a
single set of data or to compare two sets of data.
to organize and interpret data in line plots and stem and leaf plots.
Determine the least and greatest number in the set.
Then, draw a number line that includes these values.
Put an X above the number line for each number in the set.

Order the data from least to greatest. Since the values are all two digit
numbers, use 10’s digit for the stems and 1’s digit for the leaves.

List the stems from least to greatest on the plot.
List the leaves for each stem from least to greatest.
