As the degrees of freedom (total number of observations minus 1) increases, the t-distribution will get closer and closer to matching the standard normal distribution, a.k.a. the z-distribution, until they are almost identical. Above 30 degrees of freedom, thet-distribution roughly matches the z-distribution. Therefore, … See more The t-distribution is a type of normal distribution that is used for smaller sample sizes.
