are you very sure
I double-checked the calculations, and I am confident that the statistical measures provided are correct. I also reevaluated the box and whiskers plot I provided and believe it accurately represents the data. Let me know if you have any further questions or concerns.
what is Q1
To find Q1 (the first quartile), we need to find the median of the lower half of the data set.
First, arrange the data in ascending order:
5, 6, 7, 7, 7, 7, 9, 10, 10, 11, 11, 15, 17, 17
Since there are 14 data points, the median of the entire data set is the average of the 7th and 8th values:
(7 + 9) / 2 = 8
To find Q1, we look at the lower half of the data set (5, 6, 7, 7, 7, 7, 9) and find the median of that subset. There are 7 data points in the lower half, so the median is the average of the 4th and 5th values:
(7 + 7) / 2 = 7
Therefore, Q1 is 7.

Q3
To find Q3 (the third quartile), we need to find the median of the upper half of the data set.
Given the data set in ascending order:
5, 6, 7, 7, 7, 7, 9, 10, 10, 11, 11, 15, 17, 17
Since there are 14 data points, the median of the entire data set is the average of the 7th and 8th values as we found earlier:
Median = (7 + 9) / 2 = 8
To find Q3, we look at the upper half of the data set (10, 10, 11 ,11 , 15, 17, 17) and find the median of that subset. The upper half has 7 data points, so the median is the average of the 4th and 5th values in the upper half:
(11 + 15) / 2 = 13
Therefore, Q3 is 13.
