To find the mean (average) of the given set of numbers, follow these steps:

1. Add all the numbers together.
2. Divide the sum by the total number of values.

Given numbers: 80, 99, 97, 5, 21, 23, 16, 50, 94, 93, 34

Step 1: Add the numbers:

$80 + 99 + 97 + 5 + 21 + 23 + 16 + 50 + 94 + 93 + 34 = 612$

Step 2: Divide the sum by the number of values (which is 11):

$\frac{612}{11} = 55.64$

The mean of the given numbers is 55.64.

1. Find the median of the same set of numbers.
2. What is the mode of this set of numbers?
3. Calculate the range of the numbers.
4. Find the variance of the numbers.
5. Calculate the standard deviation of the set.

Tip: The mean is sensitive to extremely high or low numbers (outliers), which can affect the result significantly.
