Calculating P Value is a crucial step in statistical hypothesis testing. It helps determine the significance of observed data and allows researchers to make informed decisions about the null hypothesis.
Formula: The P Value is calculated using statistical formulas involving the observed and expected values along with the degrees of freedom. It provides a measure of the evidence against a null hypothesis.
How to Use:
- Enter the observed value in the designated field.
- Input the expected value.
- Specify the degrees of freedom.
- Click the “Calculate” button to obtain the P Value.
Example: Suppose you conducted an experiment with observed results differing from the expected values. Enter these values along with the degrees of freedom to determine the P Value.
FAQs:
