Q. What is the mean?\newline−3-3, 99, −8-8, −10-10, −8-8
  1. Identify data set: Identify the data set and the number of values in the set.\newlineData set: −3,9,−8,−10,−8-3, 9, -8, -10, -8\newlineNumber of values in the set: 55
  2. Calculate sum: Calculate the sum of all the values in the data set.\newlineSum = (−3)+9+(−8)+(−10)+(−8)(-3) + 9 + (-8) + (-10) + (-8)\newlineSum = −3+9−8−10−8-3 + 9 - 8 - 10 - 8\newlineSum = −20-20
  3. Find mean: Divide the sum by the number of values to find the mean.\newlineMean = SumNumber of values\frac{\text{Sum}}{\text{Number of values}}\newlineMean = (–20)5\frac{(–20)}{5}\newlineMean = –4–4
