Calculate Score for T-Distribution

When you take a peek at t-distribution table or the t-statistic calculator, you can see that one needs to know what the “df” actually symbolizes. “df” is the “degrees of freedom” which is just one less than the sample size.

What is T-Distribution?

T-Distribution, also known as Student’s T Distribution is a family comprised of distributions that seem almost identical with regards to the curve for normal distribution. However, it is a bit smaller and wider. T-distribution comes in use when there are small samples available. With an increase in the size of the sample, t-distribution starts looking more like normal distribution. For sample size that exceeds 20, t-distribution seems exact the same as normal distribution. With the help of a t-distribution table, one can easily calculate the score for the same.

T-score is the standardized statistic test that enables one to obtain individual score while transforming it to the common form for comparison of scores. The formula for t-score for the t-score calculator is: T= t = [x̄ - μ0] / [s / sqrt( n ) ]
