T-distribution:T-distribution is a distribution that is used when the sample size is small. A sample is said to be small in case the number of elements in a sample is less than 30. In t-distribution, as the degrees of freedom increase, the t-distribution collapses into a normal...
Understand what the t-distribution is and when to use the Student t-distribution. Learn the t-distribution formula and how degrees of freedom effects the t-curve. Related to this Question In a study using 9 samples, and in which the popul...
In a one-sample t test, calculating degrees of freedom is simple: one less than the number of objects in your dataset (you’ll see it written asn-1). Example of a one sample t test For our example within Prism, we have a dataset of 12 values from an experiment labeled “% of cont...
