T‑Score Calculator
Calculate the T‑score using: $$ T = \frac{x – \bar{x}}{SD/\sqrt{n}}. $$
* Enter the observed value (\(x\)), sample mean (\(\bar{x}\)), standard deviation (SD), and sample size (\(n\)).
Step 1: Enter Your Data
e.g., 100

How It Works
The T‑score measures how many standard errors an observed value is from the sample mean.
It is computed as: $$ T = \frac{x – \bar{x}}{SD/\sqrt{n}}, $$ where:
- \( x \) is the observed value,
- \( \bar{x} \) is the sample mean,
- SD is the sample standard deviation, and
- \( n \) is the sample size.
Simply enter your data and click “Calculate T‑Score” to see how far your observation deviates from the mean in terms of standard errors.
