Question

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

Explanation:

Step1: Count dots for each value

For value 1, there are 4 dots; for $1\frac{1}{2}$ there are 2 dots; for 2 there are 7 dots; for $2\frac{1}{4}$ there are 3 dots.

Step2: Check each data - set

The second data - set: 1, 1, 1, 1, $1\frac{1}{2}$, $1\frac{1}{2}$, 2, 2, 2, 2, 2, 2, 2, $2\frac{1}{4}$, $2\frac{1}{4}$, $2\frac{1}{4}$ has the correct frequencies for each value as per the line - plot.

Answer:

1, 1, 1, 1, $1\frac{1}{2}$, $1\frac{1}{2}$, 2, 2, 2, 2, 2, 2, 2, $2\frac{1}{4}$, $2\frac{1}{4}$, $2\frac{1}{4}$
