Webb16 mars 2024 · T Distribution vs. Z Distribution. When the degree of freedom, the total observations minus one, increases, the t distribution is almost identical to the normal distribution. 3 At a degree of freedom of 30, the t distribution graph becomes similar to the standard normal distribution. Hence, as the sample size increases, you can use the z … WebbThe t-distribution is similar to a normal distribution. It has a precise mathematical definition.
