Data Analysis and Probability Mean and median of a data set

\newline

A group of

7

students was,asked,

Arrange Data in Ascending Order: First, let's arrange the data in ascending order: $6, 6, 8, 9, 11, 11, 18$ .
Find the Median: Now, to find the median, which is the middle number when the data is ordered, we count $7$ numbers, so the median is the $4$ th number: $9$ .
Calculate the Mean: For the mean, we add all the numbers together: $6 + 6 + 8 + 9 + 11 + 11 + 18 = 69$ .
Divide Sum by Number of Data Points: Then, we divide the sum by the number of data points, which is $7$ : $69 / 7 = 9.857$ .
Round Mean to Nearest Tenth: We round the mean to the nearest tenth: $9.857$ rounds to $9.9$ .
