This lesson covers;

  • Using 2 IF functions to perform 3 possible actions upon the test result.
  • An understanding of how to structure multiple IF functions.
Nesting Multiple IF Functions

An IF function can only perform one logical test, or condition. If you need to perform multiple conditions then you may need the AND or OR function. These are commonly combined with the IF function to perform actions based on multiple conditions.

This lesson covers;

  • Understanding the difference between the AND and OR functions and what they do.
  • The syntax of AND and OR.
  • How to use these functions with IF.

  • Counting the unique entry of names in a list.
Counting the Unique Values in a Range
Calculating Averages
7 Lectures 21:07

When people refer to calculating the average, they are normally referring to the mean average. This is calculated by dividing the sum of a range of values by its count.

This process is simplified by using the AVERAGE function in Excel. Blank cells and cells containing text are excluded from the calculation.

Finding the Mean Average

The AVERAGEIF function can be used to calculate the mean average for a range of values that meet a single criterion.

This lesson covers;

  • Understanding the syntax of the AVERAGEIF function.
  • Calculating the average for values that meet specific criteria.
