How do you find the mean?

Question

I have a graph

Answer 1

To find the mean from a graph, you will need to add up all the values on the graph and then divide by the total number of values.

1. Look at the graph and identify all the data points or values that are shown.
2. Add up all the values.
3. Count the total number of values.
4. Divide the sum of the values by the total number of values to find the mean.

For example, if you have a graph with the values 2, 4, 6, and 8, you would add these values together (2 + 4 + 6 + 8 = 20) and then divide by the total number of values (4 in this case) to get the mean (20 / 4 = 5). So, in this example, the mean of the data on the graph is 5.

Answer 2

Ok so my graph is # of students (y axis) by number of hours (x axis)
8 students do homework for 1 hour
6 students do homework for 2 hours
4 students do homework for 3 hours
2 students do homework for 4 hours
1 student does homework for 5 hours
What's the mean?

Answer 3

To find the mean, we first need to calculate the total number of hours spent by all students doing homework:

8 students x 1 hour = 8 hours
6 students x 2 hours = 12 hours
4 students x 3 hours = 12 hours
2 students x 4 hours = 8 hours
1 student x 5 hours = 5 hours

Next, add up all the total number of hours:

8 + 12 + 12 + 8 + 5 = 45 hours

Now, divide the total number of hours by the total number of students:

45 hours / 21 students = 2.14 hours

Therefore, the mean number of hours spent by each student doing homework is approximately 2.14 hours.
