How do you solve for the mean?

• Add all of the numbers in the data set together then divide by 2

  
  

  Ex: 0, 1, 2, 3, 4, 5

  (1 + 2 + 3 + 4 + 5) / 2

  (15) / 2

  7.5

• Add all of the numbers in the data set together then divide by how many numbers are in the data set

  
  

  Ex: 0, 1, 2, 3, 4, 5

  (1 + 2 + 3 + 4 + 5) / 6

  (15) / 6

  2.5
