Question

hours spent on chores per week
which data set matches the line plot?
data set:
1, 1, 1, 1 1/2, 1 1/2, 2, 2, 2, 2, 2 1/4
data set:
1, 1 1/2, 2, 2 1/4
data set:
3/4, 1, 1 1/4, 1 1/2
data set:
1, 1, 1 1/4, 1 1/4, 1 1/2, 2, 2 1/4

Explanation:

Step1: Count data - points for each value

Count the number of dots at each value on the line - plot to match with the data - sets. At value $1$, there are 4 dots; at value $1\frac{1}{2}$, there are 2 dots; at value $2$, there are 5 dots; at value $2\frac{1}{4}$, there are 3 dots.

Step2: Match with data - sets

Go through each data - set and check if the frequency of each value matches the counts from the line - plot.
The data - set that matches is: $1,1,1,1,1\frac{1}{2},1\frac{1}{2},2,2,2,2,2,2\frac{1}{4},2\frac{1}{4},2\frac{1}{4}$

Answer:

The data - set that matches the line plot is $1,1,1,1,1\frac{1}{2},1\frac{1}{2},2,2,2,2,2,2\frac{1}{4},2\frac{1}{4},2\frac{1}{4}$
