1. ### Is 2-way ANOVA appropriate?

You can use a 2-way ANOVA but notice that it is a repeated measures ANOVA. That is, you have one in-between groups variable (Treatment) and one within groups variable. You also should notice that since you will want to use an alpha correction, it is best you have a large sample.
2. ### Is there a test that can be used to compare these?!?

If I understand correcly, you have 4 means for each element, but not the values themselves. If you have the number of of modalities used to calculate these means, AND the standard deivation, then yes. You can use an ANOVA.

4. ### How do you perform statistical analysis on a multiple response variable on SPSS Statistics?

You can turn the variable into several dummy variables. But be careful with the analyses since the new variables will not be mutually exclusive.
5. ### ANCOVA with moderators

Not exactly. A moderation effect might be found if you test the three 3-way interactions.
6. ### ANCOVA with moderators

You will have 3 dummy variables and 2 moderators. That is 6 2-way interactions. However, to truly understand the relationship between the variables you will have to also calculate another 3 3-way interactions. 9 in total (not 15, which for some reason seemed logical to me as I wrote my previous...
7. ### What statistical analysis to preform - ANOVA?

Karabiner, did you notice that the dependent variable seems to be a count variable? I am not sure ANOVA is appropriate here.
8. ### One-tailed OR two-tailed

I would check the literature in your field and see what is usually done there.
9. ### ANCOVA with moderators

If you don't include the interaction variables you won't be able to test for moderation. So, if you don't want to use moderating varaibles as covariates (which to be honest, I am not sure if you should do or not), I can think of 2 options.: 1. Use a regression analysis. Problem is, you will have...
10. ### Possible statistical analysis confusion?

ANOVA with 2 groups is essentially the same thing as t-test. So you can choose either one. However, I never saw anyone actually use ANOVA with only 2 groups. So go with t-test.
11. ### Not sure what test to use- HELP

yashrampersad, why did you think about a paired sample test? What is the prominent feature of such a test?
12. ### Dummy Variable Help

I assume you only tried to create dummy variables from the time period variable (as there is no apparent reason to create them from the year variable). Seems ok to me.
13. ### Help with Combining Variables

Ok, so this is your problem. To choose multiple options you should seperate the conditions and use the "|" sign in your syntax. For example, (country_language = Sweden_Finnish) | (country_language = Sweden_English).
14. ### Help with Combining Variables

Try using the "Select cases" option in the "Data" menu.
15. ### Test choice

Either that or a chi-square test.
16. ### LDA analysis

Hi mariia.maak. I am not familiar with LDA analysis. However, after reading a bit about it, it seems it is somewhat similiar to factor analysis. In factor analysis we take N varaibles and try to combine them into M factors, where N>M. This might explain the answer. Again, I'm not familiar with...
17. ### one way anova

Hi bshiels87. Since this is obviously a homework question, I'll give you a hint. You actually have 2 independent varaibles. One is, as you mentioned, the group variable (intervention/control). But there is another one. Think about it.
18. ### Help on research materials

The best way to find research topics is to read your instructor's latest publishments and search for a question that is left unanswered. It is very helpful to choose a topic that your instructor is familiar with, so he can easily help and guide you to relevant resources. Plus, he will have a...
19. ### Assessing ordinal interactions

Hi everyone I performed a 2X3 ANOVA and got an ordinal interaction. One variable was pre/post treatment and the other was type of measurement. The thing is, all p's are significant (p<0.001). So, how can I tell if there are differences in the significant differences? That is, all measurements...
20. ### Confidence interval in inter-rater reliability

When I calculate the confidence interval for the same sample using a t test, the mean is exactly in the middle of the interval.
