The Student t density with 1, 3 and 10 degrees of freedom, against the standard normal. Fewer degrees of freedom mean heavier tails, and therefore larger quantiles and wider intervals. By 10 degrees of freedom the curve is already close to normal.

Summary

Description. The Student t density with 1, 3 and 10 degrees of freedom, against the standard normal. Fewer degrees of freedom mean heavier tails, and therefore larger quantiles and wider intervals. By 10 degrees of freedom the curve is already close to normal.

Appears in. Confidence intervals

Made by. Drawn with Python and matplotlib from the example data. One script draws every figure in its section.
