Question
(7 points) On the next page, there are some data presented for a SPSS analysis of the effect of diet type (three different diets) on clutch size of zebra finches. 8. What are the "first steps" towards analyzing these data that this researcher has taken? Also explain the outcome. a. Based on the results (the outcome) of these "first steps", what is the most appropriate analysis method to apply to these data? Why- what is it about the information that you have that tells you this method is appropriate? b. Test of Homogeneity of Variances eggs3 Levene Statistic df1 df2 Sig. 10.924 2 21 001Explanation / Answer
Question 8
Part a
The first steps towards analyzing the given data, the researcher should use the analysis of variance or ANOVA F test for checking the hypothesis whether there is any statistically significant difference between the effects of three types of different diets. The ANOVA F test concludes that there is significant difference in group means. This facts force to use the post hoc test for given ANOVA F test.
Part b
Based on the results of ANOVA test for the given data for three different types of diets, it is useful to apply post hoc test for checking the homogeneity of variances. For the post hoc test, we can use Levene or LSD test for checking the homogeneity of variances. For the given scenario, the Levene statistic is given as 10.924 with p-value as 0.001 (P-value < = 0.01 or 0.05).Thus, p-value indicates that there is no homogeneity of variances for the data for given three types of diets. There is statistically significant difference between three different diets.
