Grade 4 Line Plots and Data Practice Test

Build Grade 4 Math skills with five 10-question practice tests on line plots, data sets, frequency, range, mode, and measurement data.

Line Plots and Data Practice Tests

These Grade 4 Math practice tests help students read line plots and analyze measurement data. Students count marks, identify the mode, find the range, compare groups, and calculate totals from repeated measurements.

Skills covered

  • Reading values and frequencies on line plots
  • Counting data points and marks
  • Finding the mode and range
  • Comparing frequencies and groups
  • Adding repeated measurements to find totals
  • Interpreting line plots with fractional scales

How to use these practice tests

Each mark on a line plot represents one data value. Count the marks above a value to find its frequency. The mode is the value with the most marks, and the range is the greatest value minus the least value. For repeated measurements, multiply a value by its number of marks before adding.

1. QuestionMultiple choice

A line plot uses intervals of 12\frac{1}{2} inch. Which value is halfway between 1 and 2 inches?

Please select an answer first.

Correct answer: A

The correct answer is 32\frac{3}{2} inches.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: The halfway point between 1 and 2 is 32\frac{3}{2} inches.
  3. Check the scale: The correct choice is 32\frac{3}{2} inches.

The halfway point between 1 and 2 is 32\frac{3}{2} inches.

2. QuestionMultiple choice

A line plot has 2 marks at 14\frac{1}{4} inch, 3 marks at 12\frac{1}{2} inch, and 1 mark at 34\frac{3}{4} inch. Which measurement occurs most often?

Please select an answer first.

Correct answer: B

The correct answer is 12\frac{1}{2} inch.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: The value 12\frac{1}{2} has 3 marks, the most in the plot.
  3. Check the scale: The correct choice is 12\frac{1}{2} inch.

The value 12\frac{1}{2} has 3 marks, the most in the plot.

3. QuestionMultiple choice

The data are 14\frac{1}{4}, 14\frac{1}{4}, 12\frac{1}{2}, 34\frac{3}{4}. What is the total number of measurements?

Please select an answer first.

Correct answer: C

The correct answer is 4.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: Count the four data values.
  3. Check the scale: The correct choice is 4.

Count the four data values.

4. QuestionMultiple choice

The smallest length is 12\frac{1}{2} inch and the greatest is 32\frac{3}{2} inches. What is the range?

Please select an answer first.

Correct answer: D

The correct answer is 1 inch.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: Range = 32\frac{3}{2} − 12\frac{1}{2} = 1 inch.
  3. Check the scale: The correct choice is 1 inch.

Range = 32\frac{3}{2} − 12\frac{1}{2} = 1 inch.

5. QuestionMultiple choice

A line plot has 4 marks at 14\frac{1}{4} and 2 marks at 34\frac{3}{4}. How many more marks are at 14\frac{1}{4}?

Please select an answer first.

Correct answer: A

The correct answer is 2.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: Subtract the counts: 4 − 2 = 2.
  3. Check the scale: The correct choice is 2.

Subtract the counts: 4 − 2 = 2.

6. QuestionMultiple choice

Which value is greatest: 12\frac{1}{2}, 34\frac{3}{4}, or 14\frac{1}{4}?

Please select an answer first.

Correct answer: B

The correct answer is 34\frac{3}{4}.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: Three fourths is greater than one half and one fourth.
  3. Check the scale: The correct choice is 34\frac{3}{4}.

Three fourths is greater than one half and one fourth.

7. QuestionMultiple choice

A line plot shows 3 marks at 12\frac{1}{2} inch and 3 marks at 1 inch. How many marks are shown?

Please select an answer first.

Correct answer: C

The correct answer is 6.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: Add the two groups: 3 + 3 = 6 marks.
  3. Check the scale: The correct choice is 6.

Add the two groups: 3 + 3 = 6 marks.

8. QuestionMultiple choice

The data are 14\frac{1}{4}, 12\frac{1}{2}, 12\frac{1}{2}, 34\frac{3}{4}. What is the mode?

Please select an answer first.

Correct answer: D

The correct answer is 12\frac{1}{2}.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: One half appears twice, more than the other values.
  3. Check the scale: The correct choice is 12\frac{1}{2}.

One half appears twice, more than the other values.

9. QuestionMultiple choice

A line plot has 1 mark at 14\frac{1}{4}, 2 marks at 12\frac{1}{2}, and 3 marks at 34\frac{3}{4}. How many measurements are at least 12\frac{1}{2}?

Please select an answer first.

Correct answer: A

The correct answer is 5.

  1. Read the data: Use the values and the number of marks at each value in the line plot.
  2. Calculate or compare: At least one half includes 2 marks at one half and 3 marks at three fourths: 5.
  3. Check the scale: The correct choice is 5.

At least one half includes 2 marks at one half and 3 marks at three fourths: 5.

10. QuestionMultiple choice
