What is the mean? –5, –8, –6, –9, –7, –6, –6, –7, –8, –8 _____

List Data Set: List the data set and identify the numbers to be used in the calculation. Data set: –5, –8, –6, –9, –7, –6, –6, –7, –8, –8 We will use these numbers to calculate the mean.Find Sum: Add all the numbers together to find the sum. Sum = (–5) + (–8) + (–6) + (–9) + (–7) + (–6) + (–6) + (–7) + (–8) + (–8) Sum = –70Count Values: Count the number of values in the data set. There are 10 numbers in the data set.Calculate Mean: Divide the sum by the number of values to find the mean. Mean = Sum / Number of values Mean = (–70) / 10 Mean = –7

Q. What is the mean?

\newline

-5, -8, -6, -9, -7, -6, -6, -7, -8, -8

List Data Set: List the data set and identify the numbers to be used in the calculation. $\newline$ Data set: $-5$ , $-8$ , $-6$ , $-9$ , $-7$ , $-6$ , $-6$ , $-7$ , $-8$ , $-8$ $\newline$ We will use these numbers to calculate the mean.
Find Sum: Add all the numbers together to find the sum. $\newline$ Sum = $(-5) + (-8) + (-6) + (-9) + (-7) + (-6) + (-6) + (-7) + (-8) + (-8)$ $\newline$ Sum = $-70$
Count Values: Count the number of values in the data set. $\newline$ There are $10$ numbers in the data set.
Calculate Mean: Divide the sum by the number of values to find the mean. $\newline$ Mean = $\frac{\text{Sum}}{\text{Number of values}}$ $\newline$ Mean = $\frac{(–70)}{10}$ $\newline$ Mean = $–7$
