How do you find the T score?
The formula for the t score is the sample mean minus the population mean, all over the sample standard deviation divided by the square root of the number of observations. The sample mean, sample standard deviation and number of observations are all available in the data from your sample.
How do you calculate TDF in statistics?
The degrees of freedom for a t-distribution can be derived from the sample size - just subtract one. (degrees of freedom = sample size - 1). You can use this as a critical value calculator with sample size.
