The t distribution is similar to the z distribution in that it is bell-shaped and symmetrical around the mean. However, it is associated with greater variability and is characterized by thicker tails compared to the z distribution. This means that scores are more likely to be in the tails of the distribution, which can make it more suitable for analyzing data with smaller sample sizes or when population parameters are unknown.
