Question

What does it mean when the statistical significance = p value is! equal 0.051? Select one: O a. The alternate (research) hypothesis is not rejected. b. The null hypothesis is is not rejected. c. The null hypothesis is rejected. d. none of the above.

Answer 1

p-VALUE

It is the common output of a statistical test. It is used as an alternative to rejection points to provide the smallest level of significance at which the null hypothesis would be rejected.

NULL HYPOTHESIS

It is an indication of how something is expected to function normally without any change.

ALTERNATIVE HYPOTHESIS

Expected change during a test by controlling one or more variables.

Any change from the null being true or the alternative being true will be described numerically by p-value.

p-values are useful tool for interpreting research findings.

             p-value                        interpretation

                   >0.05                        accept the null hypothesis

           <or=0.05                   reject null hypothesis

CONCLUSION

p-value is the probability the null hypothesis is true.

Low p-value indicates the result is statistically significant.

High p-value indicates the result is not significant.
