WebA normal distribution curve is plotted along a horizontal axis labeled, Trunk Diameter in centimeters, which ranges from 60 to 240 in increments of 30. The curve rises from the horizontal axis at 60 with increasing steepness to its peak at 150, before falling with decreasing steepness through 240, then appearing to plateau along the horizontal ... WebOct 5, 2024 · The t-distribution is similar to the normal distribution, and as sample size increases it gradually becomes identical to the normal distribution. The term “t-distribution” actually refers to a family of distribution curves, because the curve changes according to the experiment’s sample size.
