Make a line plot for the set of data
61,58,57,64,57,64,58,56,57
First, we need to create a number line that includes all the possible values in the data set. In this case, the smallest number is 56 and the largest number is 64. Therefore, we will create a number line that starts from 55 and goes up to 65 with intervals of 1.
55 -- 56 -- 57 -- 58 -- 59 -- 60 -- 61 -- 62 -- 63 -- 64 -- 65
Next, we will plot a dot above each number on the number line representing the frequency of that number in the data set. For instance, the number 61 appears once in the data set, so we plot one dot above 61 on the number line. The number 57 and 64 each appear twice in the data set, so we plot two dots above 57 and two dots above 64 on the number line. We repeat this process for all the numbers in the data set.
Here is the completed line plot:
