What is the relationship between T and p-value?
The larger the absolute value of the t-value, the smaller the p-value, and the greater the evidence against the null hypothesis.
How do you interpret critical t-value?
The t-critical value is the cutoff between retaining or rejecting the null hypothesis. Whenever the t-statistic is farther from 0 than the t-critical value, the null hypothesis is rejected; otherwise, the null hypothesis is retained.
How do you interpret T-scores?
T-scores are standardized scores on each dimension for each type. A score of 50 represents the mean. A difference of 10 from the mean indicates a difference of one standard deviation. Thus, a score of 60 is one standard deviation above the mean, while a score of 30 is two standard deviations below the mean.
