simple ANOVA lab
October 29, 2009
Lab this week will focus on using spss to calculate oneway independent and repeated measures ANOVA. We will also be focusing on post-hoc tests and interpretation. The lab directions, as always, can be found on the content page.
Share your conclusions here as comments. (Then start reading chapter 12).

One Way Anova:
There is a at least one diet that is significantly different than at least on other rat diet. F(3,32)= 7.096 sig=.001 All groups that are given safflower oils are significantly different than the other groups, and no significance between the other groups,according to the LSD post hoc test.
Repeated Measures:
There is a significant difference between at least one group in regards to the fatigue with the speed that workers can assemble pocket calculators of another group. F(2,18)= 40.737 sig=.001

One way Anova…
At least one rat’s diet is significantly different then at least one other rat’s diet F(3,32)= 7.096, p=.001. There is a significant difference in the cholesterol levels in the rats that had diets with safflower oil, but there is no difference between diets that had no safflower oil by the lsd test p< .001.
Repeated Measures…
At least one shift of the workers performance was significantly different then another shift F(2, 18)= 40.737, p= .001.

there is a significant difference between the HDL ratios in the diets the rats were given. F(35)=2.096, p=.001. according to the LSD test, diet 2 is significantly different than all the other diets. diets 1, 3, and 4 are only slightly different (no significant difference).

There is a significant difference between each diet.
F(35) = 7.096, p= .01. Diet two is significantly different from the other diets. Diet one, three and four are all slightly different.

There is a significant difference in the HDL ratio of each diet, F(35)=7.096, p=.001. Diet 2 is significantly different than 1,3,and 4, while diets 1,3,and 4 are only slightly different from each other.

Repeated Measures
There is a significant difference in performance between 1 group and at least 1 other. F(2,18)=40.737, p<.001. All performances are significantly different from each other by the LSD test.

One-Way ANOVA: At least one of the dietary fat conditions significantly affects visual discrimination, F(3,32)= 7.096, p= .001
LSD: There is only a significant difference between the safflower oil diets and the rest of the diets, all the other diets showed no significant difference between them according to the LSD test, p=.001
Repeated Measures: In at least one portion of the workers’ shift there is a significant effect of fatigue on the workers’ speed in assembling calculators, F(2,18)= 40.737, p< .001

There was a significant difference between the cholesterol levels between diet 2 and the rest of the groups, which did not differ. F(3,32)=7.096, p=.001.

There was a significant difference between the rats on diet 2 and the other 3 diet groups.There was no significant difference between diet groups 1, 3, and 4. F(3,32)=7.096, p=.001

Reject the h0. There is a difference among at least one of the four diets with the rats. Diet 2 was the only one that showed a difference among the diets, F(3, 32)=7.096, p=.001.

there is a significant difference between diet groups 1 and 2 of the rats. There was no significant difference between groups 1,3, and 4, F(3,32) = 7.096, p = .001.

One Way ANOVA:
There is one diet (Diet 2) that is significantly different than the other diets (Diets 1, 3, and 4), F(3, 32)= 7.096, p=.001. There is a significant difference in the rats that were given a diet with safflower oil than the ones that were not given safflower oil, and no significant difference between the other groups according to the LSD test.
Repeated Measures:
At least one shift of workers’ performance was significant different than the others, F(2, 18)= 40.737, p= .001.

There is a significant difference among the HDL cholesterol ratios seen in the diets of the rats. F(35)=7.0964, p<.001. Diets 1,3, and 4 show the least difference. Diet 2 shows the highest significance. F(2,18)=40.737,p< .001 as measured by the LSD test.

One Way Anova
There is a significant difference in diet group 2 affecting visual discrimination because the rats HDL was lower than groups 1, 3, and 4 which were the same. F(3,32)=7.096,p-.001
Repeated Measures
At least one group was effected by fatigue on the speed with which the workers can assemble pocket calculators. F(2,18)=40.737, p<.01

One Way Anova Test:
Diet 1 is significantly different from Diet 2 & 3; Diet 2 is significantly different from all of the other Diets; Diet 3 is significantly different than Diet 2; Diet 4 is also significantly different than Diet 2, F(3,32) = 7.096, sig. = .001.
Repeated Measures:
There is a significant difference between the amount of time it takes the workers to assemble pocket calculators at the beginning, middle and end of their shifts, F(2,18) = 40.737, sig = .001.

One –Way Anova:
We can conclude that at least one rat’s diet is significantly different then at least one other rat’s diet.
F= (3,32) = 7.096
P= .001
P < .001
According to Fisher’s LSD test (Least Significant Difference Test), there is a significant difference in the rats whose diet consisted of safflower oil.

One Way ANOVA:
At least one of the 4 diets affects the visual discrimination, F(3,32)=7.096. After conducting a post HOC LSD test, it has been concluded that diet 2, which consisted of 5% corn oil and 20% safflower oil significantly affected visual discrimination. The other 3 diets where equal, p <.05
Repeated Measures:
There is at least one difference between the point of assembly of pocket calculators in correlation with fatigue F(2,18)=40.737. There is a significant difference between the beginning, middle, and end of an assembly of the pocket calculator correlated with fatigue as found by the LSD test, p<.001.

1. there is a significant difference between Diet2 and all other diets as evidenced by LSD 3,32, 7.096>p.05 and no significant difference between the other diets.
@. there is significant difference between all levels of fatigue between all groups in the test. as evidenced by LSD 2,27 @ 40.737 p> .05.

#4. There is a significant difference in the effect of the new therapeutic technique between at least one number of months and another number of months. F93,18)= 5.09, p<.01. Months 0-6 are all significantly different from each other as concluded by the LSD test.

1.The HDL levels for the rats placed on the diets are significantly different F(3, 32)=7.096. The safflower oil diet is significantly different from the corn oil, coconut oil, and olive oil diets by the LSD F(3,32)=7.096 p<.05.
2.There is a significant difference in the performance of the workers in the beginning, middle, and end of their shifts by the LSD F(2,18)=40.737 p<.05
