t-score
Statistical test result
A t-score is a standardized statistical value showing how far a data point falls from the mean, measured in units of standard error.
T-scores appear in hypothesis testing when sample sizes are small or population variance is unknown: The t-score exceeded the critical value, so we rejected the null hypothesis.
In medical contexts, t-scores measure bone density relative to healthy young adults: A t-score below -2.5 indicates osteoporosis.
