Frequently Asked Questions
The t-distribution is a probability distribution used in statistics, especially for small sample sizes. It is similar to the normal distribution but has heavier tails.
Degrees of freedom (df) refer to the number of independent values in a calculation. In a t-distribution, df is typically the sample size minus one.
The CDF gives the probability that a t-value is less than or equal to the given value. It is used for hypothesis testing and confidence intervals.
