Question
(10 points) On the next page, I have included output from SPSS showing a statistical test comparing soil pH values from soils of five different sites. Your job is to interpret the data. a. What type of statistical test is applied? b. What are the assumptions of this test? c. Which of these assumptions has been tested? Has it been fulfilled (i.e., is the assumption correct)? How do you know? d. Do the groups differ? How do you know? e. If they differ, what pattern of difference do they show? Which soils differ in pH? How do you know?Explanation / Answer
a) This is related to Test for means of 5 different groups, Here ANOVA test is required
b) H0 : 5 group means are not different
H1 : Atleast two group means are different
c) In this case research hypothesis is tested, and reseach hypothesis is related to alternative hypothesis(H1)
d) Yes, differ
since p value = 0.000 < 0.05
based on Decision rule : if p value < 0.05, then reject H0, i,e groups differ
