Key concepts
3 concepts
- 1
A line plot is created by plotting data points above a number line, with each point representing a measurement.
- 2
When creating a line plot with fractional data, ensure each value is rounded to the nearest fractional unit, such as one-fourth of an hour or minute.
- 3
On a line plot, the number of dots above each tick mark indicates the frequency of that particular measurement in the data set.

3 questions
A student records the time they spend reading each day for a week, rounded to the nearest quarter of an hour. The times are: Monday - 1.5 hours, Tuesday - 1.75 hours, Wednesday - 1.5 hours, Thursday - 2 hours, Friday - 1.25 hours. How many points will be above the 1.5 hours mark on the line plot?
A group of friends measured their heights to the nearest quarter of an inch. The measurements were: 60.25, 60.5, 60.5, 60.75, 61, 61, 61.25. How many unique points are there on the line plot representing these heights?
