Question 1 · 1 mark · Difficulty 1/3
A line plot shows the lengths of ribbons measured to the nearest 1/4 inch. Which of the following correctly describes what each X on the line plot represents?
- The average length of all the ribbons combined
- The difference between the longest and shortest ribbon
- The total number of ribbons measured in the data set
- One data value — one ribbon with that specific length
Show answer & explanation
✓ Answer: D — One data value — one ribbon with that specific length
Each X on a line plot represents one individual data value — in this case, one ribbon of that specific length. Option B describes the total count of all X marks, not what a single X means. Option D describes the mean, which is calculated from the data, not shown by a single X. Option A describes the range, another statistical measure derived from the full data set.
