What is the mean? 0, –1, –1, 1, 1, –2, –3, –1, –3 _____

List Data Set: List the data set and identify the numbers to be used in the calculation. Data set: 0, –1, –1, 1, 1, –2, –3, –1, –3Find Sum: Add all the numbers in the data set to find the sum. Sum = 0 + (–1) + (–1) + 1 + 1 + (–2) + (–3) + (–1) + (–3) Sum = 0 – 1 – 1 + 1 + 1 – 2 – 3 – 1 – 3 Sum = –9Count Values: Count the number of values in the data set. There are 9 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 = (–9) / 9 Mean = –1

Q. What is the mean?

\newline

0, -1, -1, 1, 1, -2, -3, -1, -3

List Data Set: List the data set and identify the numbers to be used in the calculation. $\newline$ Data set: $0$ , $-1$ , $-1$ , $1$ , $1$ , $-2$ , $-3$ , $-1$ , $-3$
Find Sum: Add all the numbers in the data set to find the sum. $\newline$ Sum = $0 + (\text{-}1) + (\text{-}1) + 1 + 1 + (\text{-}2) + (\text{-}3) + (\text{-}1) + (\text{-}3)$ $\newline$ Sum = $0 \text{-} 1 \text{-} 1 + 1 + 1 \text{-} 2 \text{-} 3 \text{-} 1 \text{-} 3$ $\newline$ Sum = $\text{-}9$
Count Values: Count the number of values in the data set. $\newline$ There are $9$ 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 = $\frac{(–9)}{9}$ $\newline$ Mean = $–1$
