Question

number of runs scored
what is a dot plot and how do you read it?
check all that apply.
☐ a dot plot displays data values as dots above a number line.
☐ dot plots show the frequency with which a specifi item appears in a data set.
☐ there was 1 run in 5 of the games.
☐ there were 0 runs in 2 of the games.
☐ dot plots show the distribution of the data.
☐ there were a total of 19 games.

Explanation:

Step1: Analyze Option 1

A dot plot does display data values as dots above a number line. This is a fundamental characteristic of a dot plot. So this option applies.

Step2: Analyze Option 2

Dot plots are used to show the frequency (how often) a specific data item appears. The dots above each number on the number line represent the frequency of that number in the data set. So this option applies.

Step3: Analyze Option 3

Looking at the dot plot, above "1" there are 4 dots (not 5). So this statement is incorrect.

Step4: Analyze Option 4

Above "0" on the dot plot, there are 2 dots. Each dot represents a game, so there were 0 runs in 2 of the games. This is correct.

Step5: Analyze Option 5

Dot plots show how data is distributed (e.g., spread out, clustered). So this option applies.

Step6: Analyze Option 6

Count the total number of dots: For 0: 2, 1: 4, 2: 6, 3: 4, 4: 2, 6: 1. Sum: \(2 + 4+6 + 4+2 + 1=19\). So there were a total of 19 games. This is correct.

Answer:

• A dot plot displays data values as dots above a number line.
• Dot plots show the frequency with which a specific item appears in a data set.
• There were 0 runs in 2 of the games.
• Dot plots show the distribution of the data.
• There were a total of 19 games.
