Line Plot (Dot Plot) Statistics Example 1
Follow the full solution, then compare it with the other examples linked below.
Example 1
easyStudents measured the lengths of 10 leaves (in cm): 5, 6, 5, 7, 6, 5, 8, 6, 7, 5. Create a line plot (dot plot on a number line) for this data.
Solution
- 1 Step 1: Draw a number line from 5 to 8.
- 2 Step 2: For each data value, place an X (or dot) above the corresponding number: 5 appears 4 times, 6 appears 3 times, 7 appears 2 times, 8 appears 1 time.
- 3 Step 3: Stack the X marks vertically. The result shows 4 X's above 5, 3 X's above 6, 2 X's above 7, and 1 X above 8.
Answer
Line plot with X marks: above 5: XXXX, above 6: XXX, above 7: XX, above 8: X.
A line plot (also called a dot plot) displays data along a number line, with one mark for each data value stacked vertically. It makes it easy to see the frequency of each value and the overall distribution shape at a glance.
About Line Plot (Dot Plot)
A line plot (also called a dot plot) is a diagram that displays data values as marks — usually X's or dots — stacked above their corresponding values on a number line. Each mark represents one data point, making it easy to see the frequency of each value.
