To create a line plot, there are a few simple steps that we need to follow:

  • First, we draw a number line and choose a number range that will cover all the data points.
  • We then need to label each number with the appropriate values from the dataset.
  • Next, we plot the data. For each value in the dataset, we place a dot or an X above the corresponding number. If a number in the dataset is repeated, we stack multiple dots or Xs above the corresponding number.
  • Finally, we read the line plot. This means we need to identify the most common and least common values, look for any patterns or gaps in the data.

How to Read a Line Plot?


Reading a line plot is easy if you follow these steps:


Step 1: Look at the title to understand what the graph is about.

Step 2: Check the number line to see the values being measured.

Step 3: Observe the marks (dots or Xs) placed above each value.

Step 4: Count the marks to find the frequency of each value.

Step 5: Compare heights of stacks to understand which values occur most or least often.

Step 6: Use the pattern of marks to interpret trends, gaps, or clusters in the data.

Line Plot with Fractions
A line plot with fractions is constructed just like any other line plot. Fractional values are placed along the number line, and the number of times each fraction appears in the dataset is shown by stacking dots or Xs above them. For example, consider the data showing the lengths of ribbons (in meters) cut by 12 students for an art project.
 

Data in meters:
¼, ½, ¾, 1, ½, ¼, 1¼, ¾, 1, ½, 1¼, ¼
 

A line plot can be drawn by marking fractional lengths such as ¼, ½, ¾, 1, and 1¼ on the number line and plotting dots above each to represent their frequencies.
