Furthermore, what is T score in psycho test?

T scores in psychometric testing are always positive, with a mean of 50. For example, a score of 70 is two standard deviations above the mean, while a score of 0 is one standard deviations below the mean. A t score is similar to a z score — it represents the number of standard deviations from the mean.

Secondly, what is the T score in statistics? In statistics, the t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error. For example, it is used in estimating the population mean from a sampling distribution of sample means if the population standard deviation is unknown.
