Q. What is the mode?

\newline

-8, -8, -9, 6, 1, 1, -9, -9, 6

\newline

\_\_\_\_\_

Data Set: Data set: $-8$ , $-8$ , $-9$ , $6$ , $1$ , $1$ , $-9$ , $-9$ , $6$ $\newline$ First, we need to determine how many times each number appears in the set. $\newline$ Frequency of $-9$ : $-8$ $0$ $\newline$ Frequency of $-8$ : $-8$ $2$ $\newline$ Frequency of $6$ : $-8$ $2$ $\newline$ Frequency of $1$ : $-8$ $2$
Frequency Analysis: We found: $\newline$ Frequency of $-9$ : $3$ $\newline$ Frequency of $-8$ : $2$ $\newline$ Frequency of $6$ : $2$ $\newline$ Frequency of $1$ : $2$ $\newline$ Now, we need to identify which number(s) have the highest frequency. $\newline$ The number $-9$ has the highest frequency, occurring $3$ times.
Identifying Highest Frequency: Since $-9$ has the highest frequency, it is the mode of the given data set. $\newline$ Mode: $-9$
