A T-Score is a statistical measure used to determine how far a data point is from the mean of a dataset, expressed in terms of standard deviations. It helps to understand whether a particular score is above or below the average. T-Scores are commonly used in various fields, including psychology and education, to assess individual performance compared to a group. In research, T-Scores are often derived from a T-Test, which compares the means of two groups to see if they are significantly different. A higher T-Score indicates a greater deviation from the mean, while a lower T-Score suggests that the score is closer to the average.
