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!

To find the mean number of pets in the line plot, we first need to write down the numbers that the x's represent:
2, 4, 2, 4
Next, we add the numbers together: 2 + 4 + 2 + 4 = 12
Then, we divide by the number of x's: 12 ÷ 4 = 3
Therefore, the mean number of pets is 3.
Is this answer correct
Apologies for the oversight in my previous response. Let's recalculate the mean number of pets.
The numbers represented by the x's in the line plot are: 2, 4, 2, 4
Adding these numbers together: 2 + 4 + 2 + 4 = 12
To find the mean, we need to divide the sum by the total number of entries, which is 4.
Mean = 12 / 4 = 3
Therefore, the correct mean number of pets is indeed 3.
