Q. What is the median?

\newline

1, 8, 10, 10, 9, 9, 6, 9

\newline

_____

Arrange Data in Ascending Order: Arrange the data set in ascending order. $\newline$ The data set in ascending order is: $1, 6, 8, 9, 9, 9, 10, 10$ .
Determine Number of Data Points: Determine the number of data points. The number of data points is $8$ , which is an even number.
Calculate Median for Even Data Points: Calculate the median for an even number of data points. $\newline$ The median is the average of the two middle numbers. Since there are $8$ data points, the middle numbers are the $4$ th and $5$ th values in the ordered list. $\newline$ Middle values: $9$ and $9$
Compute Average of Middle Numbers: Compute the average of the two middle numbers. $\newline$ $(9 + 9) / 2 = 9$ $\newline$ Median: $9$
