Suppose we want to merely determine whether or not subsequent blood pressure measurement where higher or lower than one another. One approach wouldbe to use the Sign Test.
Refer to the Sign Test tab in the assignment spreadsheet.
How many subjects are in the study ?
How many subjects blood pressure increased from the first measurement to the second ?
How many subjects blood pressure decreased from the first measurement to the second ?
For alpha of 0.05 two sided Test the Critical Value =
Comparing the smaller of the Positive and Negative values to the critical value which of the following is (are) true)?
a. There is statistically significant evidence at alpha=0.05 to show that Diastolic_1_Grp2 and Diastolic_2_Grp2 differ from one another.
b. There is not statistically significant evidence at alpha=0.05 to show that Diastolic_1_Grp2 and Diastolic_2_Grp2 differ from one another.
c. There are not enough data points to reach a conclusion.
d. The tied value makes the analysis suspect.
