Statistical significance essay

Any data set is deemed as statistically significant if the set if big enough to precisely represent the phenomenon under study. P-value P-value means the probability when assuming that there is no difference or effect of acquiring an outcome that is equivalent to or more extreme than the actual observation. The letter P represents probability and is used to measure the likelihood that any observable difference that occurs between variables is as a result of chance. Since it is a probability, P takes any of the values between zero and one. When the results indicate a P value that is close to zero, it means that the difference observed has no likelihood of it causation being a chance. The claim on trial in research is known as the null hypothesis.
