For a box and whisker plot, if you have an even amount of numbers which number would the mean be.
3,4,4,5,5,6,8,10,10,12,15,18
Is it 6 or 8
Thank you
Is my median 6 or 8?

Neither, it is 7.
Okay, I was wondering that also.
To determine the mean for a data set with an even number of numbers, you sum up all the numbers and divide the sum by the total count of numbers.
Here are the steps to find the mean:
1. Arrange the data set in ascending order:
3, 4, 4, 5, 5, 6, 8, 10, 10, 12, 15, 18
2. Calculate the sum of all the numbers:
Sum = 3 + 4 + 4 + 5 + 5 + 6 + 8 + 10 + 10 + 12 + 15 + 18 = 100
3. Count the total number of data points, in this case, there are 12 numbers.
4. Divide the sum by the total count of numbers to find the mean:
Mean = Sum / Total Count
= 100 / 12
= 8.33 (rounded to two decimal places)
Therefore, the mean of the given data set is approximately 8.33, which is closer to 8. The mean would be 8, not 6.
