What is a t-score and how does it differ from a z-score?
The T Score Calculator measures how many standard deviations a sample mean is from the population mean when population standard deviation is unknown. Formula: t = (x̄ - μ) / (s/√n). Unlike z-scores, t-scores account for sampling uncertainty.

How do you interpret t-score values?
Like z-scores, t-scores show standard deviations from the mean, but critical values depend on degrees of freedom. For df = 10, t > 2.228 is significant at α = 0.05 (two-tailed), compared to z > 1.96. Check t-tables for appropriate critical values.

When should you use t-scores instead of z-scores?
Use t-scores when: population standard deviation is unknown, sample size is small (n < 30), or conducting t-tests. T-scores are more conservative than z-scores, providing wider confidence intervals that account for additional uncertainty from estimating population parameters.

To eliminate thesecharacteristics, z scores often are converted to T scores. This isaccomplished using the simple formula: T score = 10(z score) + 50. Forexample, a z score of -2.5 becomes a T score of 25. Therefore, the T scorescale from 20 (-3 SD) to 80 (+3 SD) has a mean of 50 and a SD ...
