App Description
In probability and statistics, Student's t-distribution (or simply the t-distribution) is any member of a family of continuous probability distributions that arises when estimating the mean of a normally distributed population in situations where the sample size is small and population standard deviation is unknown.
The Student’s t-distribution app has three data input parameters - the Number of Degrees of Freedom (range 2-20), a Step Size parameter for evaluation points for the PDF and CDF Distributions and the Percentile parameter.
The Student’s t Distribution app also displays a touch enabled graph for the x/f(x) generated values. The graph is touch enabled graph. Upon touching the graph a vertical line appears. Move the vertical line to the left or right to display the point x/f(x).
The horizontal x-axis displays x values. The vertical y-axis plots a range of either the x-increment and y-increment values
Horizontal Max and Min dashed lines display the Maximum and Minimum values.Automatic incrementing of the value.
