What is the p value of the null hypothesis?
Fisher's P-value is defined as a conditional probability calculated using the results of a study. Specifically, the P-value is the probability of obtaining a result at least as extreme as the one that was actually observed, assuming that the null hypothesis is true.
Why is hypothesis testing important in public health?
In conclusion, hypothesis testing is indeed a vital element of public health practice given its efficacy in proving the relationship between the cause and effect. Thus, it is necessary for all medical personnel to understand this important truth for public health practice to become effective.
