Critical Ratio Formula
The following formula is used to calculate the Critical Ratio.
CRC = M / SE
- Where CRC is the Critical Ratio
- M is the difference of the means of two sets
- SE is the standard error of difference
How to Calculate Critical Ratio?
The following example problems outline how to calculate Critical Ratio.
Example Problem #1:
- First, determine the difference of the means of two sets.
- The difference of the means of two sets is given as: 5.
- Next, determine the standard error of difference.
- The standard error of difference is provided as: 2.5.
- Finally, calculate the Critical Ratio using the equation above:
CRC = M / SE
The values given above are inserted into the equation below and the solution is calculated:
CRC = 5 / 2.5 = 2.00
Example Problem #2:
For this problem, the variables required are provided below:
difference of the means of two sets = 6
standard error of difference = 4.3
Test your knowledge using the equation and check your answer with the calculator above.
CRC = M / SE = ?
