What you’ll learn

  1. Building a Line PlotBuild and read a line plot of measured data.A line plot is a number line with a mark stacked above each measured value — one mark per measurement. Taller stacks show which values occurred most often, turning a pile of measurements into a clear picture of the data.
  2. Measuring in FractionsRecord and read line-plot data measured in fractions of a unit.Measuring carefully gives lengths on fraction marks — halves, fourths, and eighths of an inch. A line plot uses those fraction positions, and measuring to the nearest eighth makes the data more precise. Read a point by the fraction mark its stack sits above.
  3. Adding Straight Off the PlotUse fraction operations on line-plot data to find totals and equal shares.Line-plot data can be added: combine the fraction lengths to find a total, such as the whole length of several ribbons. You can also share a total equally by dividing it among people. A line plot is measured data you can read, add, and share.

Questions this course answers

On a line plot, a taller stack of marks means:

Each mark is one measurement, so a taller stack means that value came up more often.

Measuring to the nearest 1⁄8 inch makes the data more:

Smaller fraction marks let you record lengths more precisely.

Two ribbons measure 1⁄4 in each. Together they are:

1⁄4 + 1⁄4 = 2⁄4, which simplifies to 1⁄2 inch.

To share a total length equally between people, you:

Split the total evenly by dividing by the number of people.

A line plot is best for showing:

Line plots display many measurements stacked over a number line.
