WebP values (or probability values) are used in hypothesis testing to represent the chance that, assuming the null hypothesis is true, you could observe the result in your study or one even more extreme. P values help researchers avoid publication errors, specifically Type I Errors. WebP-value is a number that lies between 0 and 1. The level of significance (α) is a predefined threshold that should be set by the researcher. It is generally fixed as 0.05. The formula for the calculation for P-value is Step 1: Find out the test static Z is z = p ^ − p 0 p o ( 1 − p 0) n Where, p ^ = Sample Proportion
