is closer & closer to the normal distribution. Slightly different t distributions for different d.f. HAWKES LEARNING SYSTEMS math courseware specialists Continuous Random Variables 6.5 Finding t-Values Using the Student t-Distribution Comparison of the Normal and Student t-Distributions: A t-distribution is pretty much the same as a normal distribution! There’s this additional little wrinkle of “d.f.”, “degrees of freedom”. The x-axis is a horizontal asymptote for a t-distribution curve.
The total area under a t-distribution curve equals 1. 2.Ě t-distribution curve is completely defined by its number of degrees of freedom, df.
Student’s t-Distribution Properties of a t-Distribution 1.Ě t-distribution curve is symmetric and bell-shaped, centered about 0. Section 8.2 Student’s t-Distribution With the usual enthralling extra content you’ve come to expect, by D.R.S., University of Cordele
