The t score formula enables you to take an individual score and transform it into a standardized form>one which helps you to compare scores.
You’ll want to use the t score formula when you don’t know the population standard deviation[9] and you have a small sample [10](under 30).
The t score formula is:Wherex̄ = sample meanμ0 = population means = sample standard deviationn = sample size[11][12][13][14]
If you have only one item in your sample, the square root in the denominator becomes √1. This means the formula becomes:[15]
In simple terms, the large...
