Enter the size of the effect shown in the graphic and the size of the effect shown in the data into the Lie Factor Calculator. The calculator will evaluate the Lie Factor.

## Lie Factor Formula

The following two example problems outline the steps and information needed to calculate the Lie Factor.

LF = SG / SD

Variables:

• LF is the Lie Factor ( )
• SG is the size of the effect shown in the graphic
• SD is the size of the effect shown in the data

## How to Calculate Lie Factor?

The following steps outline how to calculate the Lie Factor.

1. First, determine the size of the effect shown in the graphic.
2. Next, determine the size of the effect shown in the data.
3. Next, gather the formula from above = LF = SG / SD.
4. Finally, calculate the Lie Factor.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

size of the effect shown in the graphic = 15

size of the effect shown in the data = 10

LF = SG / SD = ?
