What Is Benchmark MA.4.DP.1.1?

Students collect and represent numerical data, including fractions, using tables, stem-and-leaf plots, and line plots.

In a stem-and-leaf plot, the stem is usually the tens digit and the leaf is the ones digit, so 6 | 2 7 means 62 and 67. In a line plot, each X marks one data value on a number line, which can be marked in fractions such as halves or fourths.

On the FAST test: part of the Grade 4 reporting category Geometric Reasoning, Measurement, and Data Analysis and Probability, which is about 31–37% of the test.

Worked Examples

Worked Example 1

Making a Line Plot

Plant heights are 3, 312, 4, 312, 412, and 3 inches. On a line plot marked in halves, how many X's go above 312?
  1. 1Mark the number line from 3 to 412 in halves.
  2. 2312 appears 2 times in the data.
Answer: 2 X's

Worked Example 2

Making a Stem-and-Leaf Plot

Show the test scores 72, 75, 81, 86, 86, 93 in a stem-and-leaf plot.
  1. 1The stems are the tens digits: 7, 8, and 9.
  2. 2The leaves are the ones digits, in order: 7 | 2 5, 8 | 1 6 6, 9 | 3
Answer: 7 | 2 5 8 | 1 6 6 9 | 3

Common Mistakes to Watch For

Leaving out repeated values

Wrong:86 and 86 shown as 8 | 1 6

Every data value gets its own leaf: 8 | 1 6 6.

Using an uneven scale on a line plot

Wrong:A line plot marked 0, 14, 12, 1

Mark equal steps: 0, 14, 24, 34, 1.

Helpful Math Tip

Measure something real, like family members' hand spans to the nearest half inch, and make a line plot together.
