# Hypothesis testing: Double negative logic, five step process

Can someone explain this material to me in simple terms?

(1) Explain the double-negative logic of hypothesis testing (eg: a scientist fails to reject the null hypothesis).

(2) What is the five-step process for hypothesis testing? Is the order important? Why or why not?

#### Solution Preview

(1) Explain the double-negative logic of hypothesis testing (e.g.: a scientist fails to reject the null hypothesis).

The general procedure of statistical testing of hypothesis is as follows:

Specify the hypothesis to be tested (called the null hypothesis) and the alternative hypothesis (the hypothesis to be accepted, in case, the null hypothesis is rejected after the test). Decide the decision rule to reject the null hypothesis based on statistical principles. Conduct the experiment and based on the outcomes of the experiment, if you cannot reject your null hypothesis, accept it. This logic is called double - negative logic. If you fail to reject the null hypothesis then accept it.

The basic logic behind this procedure is the skepticism behind the general scientific procedure. Scientists formulate hypotheses and they do research to evaluate the validity of their hypotheses. They don't accept ...

#### Solution Summary

Hypothesis testing for double negative logic and five step processes are examined.
