Enter the z-score into the T Ratio Calculator. The calculator will evaluate and display the T Ratio. 

T Ratio Formula

The following formula is used to calculate the T Ratio. 

T = (Z*10) + 50
  • Where T is the T Ratio ( )
  • Z is the z-score 

To calculate the T-ratio, multiply the z-score by 10, then add 50 to the result.

How to Calculate T Ratio?

The following example problems outline how to calculate T Ratio.

Example Problem #1:

  1. First, determine the z-score.
    • The z-score is given as: 1.25.
  2. Finally, calculate the T Ratio using the equation above: 

T = (Z*10) + 50

The values given above are inserted into the equation below and the solution is calculated:

T = (1.25*10) + 50 = 62.5

Example Problem #2: 

For this problem, the variables required are provided below:

z-score = 1.7

Test your knowledge using the equation and check your answer with the calculator above.

T = (Z*10) + 50 = ?
