Student's tTable Generator
Student's tTable Generator
Generate a customized table of Student's t values.
Instructions
 This tool generates a table of Student's t values at a critical pvalue, p_{critic} = α, and up to a maximum number of degrees of freedom, υ_{max}.
 Just submit a pair of p_{critic} and υ_{max} values.
 The tool comes handy when you don't have statistical ttables around or are working with p and t values, or degrees of freedom, not available from such tables. Avoid pausing a problem for annoying linear interpolation workarounds!
What is computed?

The tool computes a table of Student's t values (Wikipedia, 2017) from a pair of userdefined p_{critic} and v_{max} values.
 That is done by iteratively calling (i.e., looping) the very same algorithm that we use for our tvalues Calculator.
Who can use this tool?
 Anyone that need to compute tvalues for ttest hypothesis testing.
Suggested Exercises

A math teacher hypothesizes that students who are allowed to play chess two hours daily will not score significantly lower than students allowed to play chess for four hours on a trigonometry quiz. He randomly assigns 20 students to one of two groups. In one group he has students to play for two hours and in the other group he has them play four. An hour later he gives them a 10point quiz. Group results are given below:
2hour Group: 6, 7, 8, 3, 2, 6, 7, 1, 9, 4
4hour Group: 6, 6, 8, 8, 2, 5, 3, 9, 7, 4
 What is the null hypothesis, H_{0}?
 Can he reject H_{0} at the 95% confidence level? Why?
Hint: Compute first the mean and variance from both groups.
