Create line plots
key notes:
1. Understanding Line Plots:
- A line plot is a way to display data along a number line. It shows the frequency (how many times something happens) of data points.
- The data is represented with X marks above the number line at the corresponding value.
2. Components of a Line Plot:
- Title: A clear title to explain what the data represents.
- Number Line: A horizontal line with equally spaced numbers or categories to represent the data.
- X Marks: The data points are shown as X’s or dots above the corresponding numbers on the number line.
- Scale: The numbers on the line plot must be evenly spaced to show the scale of the data accurately.
3. Steps to Create a Line Plot:
- Step 1: Collect the data you want to plot.
- Step 2: Draw a horizontal number line with numbers that cover the range of your data.
- Step 3: For each data point, place an X above the corresponding number on the number line.
- Step 4: If a number appears more than once in the data, place additional X’s above it.
Learn with an example
1) A group of people played a trivia game.
Use the data in the table to complete the line plot below.
| Scores in a trivia game | |
|---|---|
| Score | Number of people |
| 5 | 1 |
| 6 | 4 |
| 7 | 7 |
| 8 | 5 |
| 9 | 3 |
| 10 | 2 |
Click to select the X’s. To clear a column, click on the number line below it.
- The first missing piece of data is for 5. Find the row for 5 in the table. 1 person scored 5. Select 1 X in the column above 5.
2) Students in Mrs. Seth’s maths class guessed a number between 1 and 5 and recorded the results.
Use the data in the tally chart to complete the line plot below.
| Guessing a number between 1 and 5 | |
|---|---|
| Number guessed | Number of students |
| 1 |  |
| 2 |  |
| 3 |  |
| 4 |  |
| 5 |  |
Click to select the Xs. To clear a column, click on the number line below it.
- The first missing piece of data is for 2. Find the row for 2 in the table, and count the tally marks. 3 students guessed 2. Select 3 X’s in the column above 2.
3)Some students sold biscuits for a fundraiser.
Use the data in the table to complete the line plot below.
| Selling biscuits | |
|---|---|
| Boxes sold | Number of students |
| 1 | 2 |
| 2 | 1 |
| 3 | 4 |
| 4 | 5 |
| 5 | 8 |
| 6 | 6 |
Click to select the X’s. To clear a column, click on the number line below it.
- The first missing piece of data is for 5. Find the row for 5 in the table. 8 students sold exactly 5 boxes of biscuits. Select 8 X’s in the column above 5.
4)Eliza figured out the scores at the end of a card game.
Use the data in the tally chart to complete the line plot below.
| Scores in a card game | |
|---|---|
| Score | Number of people |
| 4 | |
| 5 | |
| 6 | |
| 7 | |
| 8 | |
| 9 | |
| 10 | |
Click to select the X’s. To clear a column, click on the number line below it.
The first missing piece of data is for 5. Find the row for 5 in the table, and count the tally marks. 2 people scored 5. Select 2 X’s in the column above 5.
