What is the mean? –1, –5, –6, –3, –3, –3, 0 _____

List data set and identify: List the data set and identify the numbers to be averaged. Data set: –1, –5, –6, –3, –3, –3, 0 We need to add all these numbers together and then divide by the total number of numbers to find the mean.Add all numbers in data set: Add all the numbers in the data set. Sum = (–1) + (–5) + (–6) + (–3) + (–3) + (–3) + 0 Sum = –1 – 5 – 6 – 3 – 3 – 3 Sum = –21Count total numbers: Count the total number of numbers in the data set. There are 7 numbers in the data set.Divide sum by total numbers: Divide the sum by the total number of numbers to find the mean. Mean = Sum / Total number of numbers Mean = (–21) / 7 Mean = –3

Q. What is the mean?

\newline

-1, -5, -6, -3, -3, -3, 0

List data set and identify: List the data set and identify the numbers to be averaged. $\newline$ Data set: $-1, -5, -6, -3, -3, -3, 0$ $\newline$ We need to add all these numbers together and then divide by the total number of numbers to find the mean.
Add all numbers in data set: Add all the numbers in the data set. $\newline$ Sum = $(-1) + (-5) + (-6) + (-3) + (-3) + (-3) + 0$ $\newline$ Sum = $-1 - 5 - 6 - 3 - 3 - 3$ $\newline$ Sum = $-21$
Count total numbers: Count the total number of numbers in the data set. $\newline$ There are $7$ numbers in the data set.
Divide sum by total numbers: Divide the sum by the total number of numbers to find the mean. $\newline$ Mean = $\frac{\text{Sum}}{\text{Total number of numbers}}$ $\newline$ Mean = $\frac{(–21)}{7}$ $\newline$ Mean = $–3$
