P value estimate

WebThis probability is called p-value. There are 25 students in a sample. 40 is a number of samples (of size 25) she simulates to estimate the p-value. Also, p-value is NOT the probability that null hypothesis is correct. We start the whole experiment assuming that it is correct and if we fail to reject it we simply return to where we started from. http://varianceexplained.org/statistics/interpreting-pvalue-histogram/
