T Test Formula Example. T x μ s n t 74 78 3 5 10 t 3 61. This is the first set of sample you are testing.
In this article we will discuss the t test formula with an example. D f n a n b 2. This is the first set of sample you are testing.
Therefore the absolute t test value of the sample is 3 61 which is less than the critical value 3 69 at 99 5 confidence interval with a degree of freedom of 9.
The formula of t test includes 4 types of arguments. Example 1 perform a t test calculation in excel. S 2 x m a 2 x m b 2 n a n b 2. This is the number of tails for the distribution there are two types of tails are there.
