Math Problem Statement

Find the mean for the set of numbers: 1, 2, 3, 4, 5

Solution

To find the mean of the set of numbers 1,2,3,4,51, 2, 3, 4, 5, we can follow these steps:

  1. Add all the numbers together:
    1+2+3+4+5=151 + 2 + 3 + 4 + 5 = 15

  2. Count the numbers in the set:
    There are 5 numbers in this set.

  3. Divide the sum by the count:
    155=3\frac{15}{5} = 3

So, the mean of the set of numbers 1,2,3,4,51, 2, 3, 4, 5 is 3.

Here are some related questions for further exploration:

  1. How would you calculate the median of this set?
  2. What is the range of this set of numbers?
  3. How do you calculate the mean for a larger set of numbers?
  4. What is the difference between mean, median, and mode?
  5. How does the mean change if you add another number to the set?

Tip: The mean is affected by every number in the set, so adding an unusually high or low number can significantly impact it.
