What does P 0.01 mean?

The p-value is a measure of how much evidence we have against the null hypothesis. The most important thing to remember about the p-value is that it is used to test hypotheses. … A p-value less than 0.01 will under normal circumstances mean that there is substantial evidence against the null hypothesis.

What does P .05 mean?

A p-value higher than 0.05 (> 0.05) is not statistically significant and indicates strong evidence for the null hypothesis. This means we retain the null hypothesis and reject the alternative hypothesis. You should note that you cannot accept the null hypothesis, we can only reject the null or fail to reject it.

What does P 0.001 mean?

For example, a p-value of 0.001 means that a sample as extreme as that observed would occur 1 time in 1000 if the null hypothesis was true. … We may believe that this chance is small enough to discount and act (clinically/practically) as though the null hypothesis were false.

What is the difference between P and P in statistics?

In statistics we tend use the ‘hat’ notation to imply a statistic. We designate P to represent the proportion in the population. Because P is unknown and unknowable we use Phat to designate the proportion in the sample. Suppose 30 out of 100 people in my sample support Trump.
