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.

Step-1: Subtract 1 from the sample size. This is the "df".
Step-2: Look for the "df" towards the left side of any t-distribution table. Locate this column below the alpha level.

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-Distribution Calculator

T-distribution Calculator helps make the computation of cumulative probabilities an easy task. It is based on the t-statistics that calculates all the cumulative probabilities.
For calculation of t-value with the t-value calculator, one needs to have in place the following variables.
df or Degrees of Freedom
T-Score
Probability: P(T< t)
The t-value calculator helps with an easy t-score calculation that is similar to the conversion of Celsius to Fahrenheit. The formula for B score to C score conversion is: T= (B x 10) + 50

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 ) ]
Here:

x̄ = Sample Mean
μ0 = Population Mean
n = Sample Size
s = Sample Standard Deviation
