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 specific
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:

• A dot - plot is a simple way to display data. Each dot above a number on the number line represents a data point. So, "A dot plot displays data values as dots above a number line" is correct.
• The number of dots for a particular value on the number line gives the frequency of that value. So, "Dot plots show the frequency with which a specific item appears in a data set" is correct.
• For the number of runs:
• For \(0\) runs, there are \(2\) dots. So, "There were \(0\) runs in \(2\) of the games" is correct.
• For \(1\) run, there are \(3\) dots (not \(5\)), so "There was \(1\) run in \(5\) of the games" is incorrect.
• Dot - plots do show the distribution of data (by showing how the data is spread out across different values), so "Dot plots show the distribution of the data" is correct.
• To find the total number of games, we count the number of dots. \(2 + 3+5 + 1+3 + 1+1=16\) (not \(19\)), so "There were a total of \(19\) games" is incorrect.

Answer:
