The frequency table shows a set of data collected by a doctor for adult patients who were diagnosed with a strain of influenza.

A 2-column table with 4 rows. The first column is labeled age range with entries 25 to 29, 30 to 34, 35 to 39, 40 to 45. The second column is labeled number of sick patients with entries 3, 6, 5, 4.
Which dot plot could represent the same data as the frequency table?


  1. The dot plot that could represent the same data as the frequency table is  the second plot. This is further explained below.

    What is dot plot?

    Generally, Data points are represented as dots on a graph with an x- and y-axis in a dot plot sometimes referred to as a strip plot or dot chart, which is a straightforward kind of data visualization.
    The frequency table displays the number of ill patients in each age group. The first two plots are incorrect because the sum of the dots connecting the numbers 24, 25, 26, 27, 28, and 29 in the first two plots is 3, but not in the other two plots.
    In conclusion, there are only 4 ill individuals when the dots from the 30-34 age range on the first plot are added together. There are a total of 6 cases in that age group on the second graph. As a result, the second dot plot is the one that matches the frequency table.
