What is a Line Plot? (Video & Practice Questions)
Anna asked her classmates how many pets they have. This line plot shows the results. Find the MEAN number of pets.
Process: Each x represents a number. Write down the numbers that the x's represent. Add the numbers together. Divide by the number of x's. Remember, "0" still counts as a number!

The mean number of pets is:
(1 + 0 + 2 + 3 + 1 + 2 + 4 + 3 + 1 + 2 + 0) / 11 = 19 / 11 = 1.727
Therefore, the mean number of pets is approximately 1.727.
These are the answer choices
2.39
2.39
4.3

2.87
2.87
4.78
To find the mean number of pets, we add up all the numbers that the x's represent and then divide by the total number of x's.
(1 + 0 + 2 + 3 + 1 + 2 + 4 + 3 + 1 + 2 + 0) = 19
There are 11 x's in total.
Mean = 19 / 11 = 1.727
The closest answer choice to the calculated mean of 1.727 is 2.39.
