  2. Calculate sum: Add all the numbers in the data set together to find the sum.\newlineSum = 4.1+3.5+2.9+0.34.1 + 3.5 + 2.9 + 0.3\newlineSum = 10.810.8
  3. Count data points: Count the number of data points in the set.\newlineThere are 44 numbers in the data set.
  4. Find the mean: Divide the sum of the data set by the count of numbers to find the mean.\newlineMean = SumCount of numbers\frac{\text{Sum}}{\text{Count of numbers}}\newlineMean = 10.84\frac{10.8}{4}\newlineMean = 2.72.7
