Question

Use the following graph to find the mean, median, and mode

Answer 1

Given:

A graph

To determine the Mean, Median, and Mode based on the given graph, we first get the data set as shown below:

2,5,5,5,5,6,9,11,12,13,14,15,18,20

Next, we find the Mean by getting the average:

`\begin{gathered} Mean=(2+5+5+5+5+6+9+11+12+13+14+15+18+20)/(14) \\ Simplify \\ Mean=(140)/(14) \\ Mean=10 \end{gathered}`

Then, we get the Median by getting the average of the two middle values since there is an even number of data values:

`\begin{gathered} Median=(9+11)/(2) \\ Simplify \\ Median=10 \end{gathered}`

Now, we get the Mode by finding the number that appears most frequently. Hence, the Mode is 5.

Therefore, the answer is:

Mean:10, Median:10, Mode:5
