Calculate > p-Value
The p-Value tool computes p-Values for four different types of
probability distribution (Normal, Student's t, Chi-square, and F)
and three types of tests (left-tail, right-tail, two-tail), given a test
statistic and degrees of freedom (if applicable).
The inputs to the tool are:
- Distribution: Normal, Student's t, Chi-square, or Fisher
- Type of Test: Left-tail, Right-tail, or Two-tail
- Test Statistic: Sample statistic based on the sample data
- Degrees of Freedom (DOF): Number of values that are free to vary
after certain restrictions have been imposed on all values.
Computation of p-Values for different distributions requires
different number of DOF inputs:
- Normal: none
- Student's T and Chi-square: one DOF input
- F: DOF 1 and DOF 2
- Click Compute to start the p-Value computation. The result
is shown on the log window.
- Click Clear to clear all inputs (set to default).
