Question

A supervisor was comparing two different hemoglobin methods using the same set of patient samples. She wanted to compare the mean values of the two groups to detect any differences. Prior to running the comparison study, she determined the desired level of significance to be 0.05. When she completed the statistical analysis (using software) she derived a p value = 0.8.    

a. Based on what the supervisor was trying to achieve, what statistical test was most likely chosen? (Be very specific)

b. What does the derived p-value indicate about the two test methods you were comparing?

Explanation / Answer

a) here we are comparing two different hemoglobin methods using the same set of pateints and we need to test is there any difference between means of two groups. So we use Paired t test

b) Here p value=0.8 and alpha=0.05

P> alpha we accept the null htpothesis. That is there is no difference in two means
