1. ### Three-Way (2x2x2) Between-Subjects ANOVA in SPSS

I'm just wondering how I can decompose a significant 3-way interaction in SPSS (all three IVs are categorical) without splitting the file, so that my follow up degrees of freedoms in the follow up tests remain the same as the omnibus degrees of freedom?
2. ### two way ANOVA?

Dear all, I'm currently working on my thesis, which is an analysis of the effects of social cycling on cyclists' stress levels. An experiment with a total of 21 participants was conducted. The Experiment was about a comparison between single cycling vs group cycling. Single rides and group...
3. ### Can this data be calculated by SPSS? and how?

I want to get the value of x2 and p in every row, may I ask how I can calculate them by SPSS?
4. ### How can I create a table with 2 independent numeric variables in SPSS?

I'm trying to tabulate some concentrations of compounds to eventually test if tide (or depth for other samples) and distance along a sampling transect affect these compounds (the 5 variables on the right). However, the only way I can think to do this is in the attached image, where I'm forced to...
5. ### Deriving a formula from an ARIMAX Model

Hello all, I am finishing my master thesis and have included an ARIMAX model in the research. Now I would like to make some manual calculations based on the results from the ARIMAX Model in SPSS. I know that the results are not all significant but this is not a concern because a simulated...
6. ### SPSS Analysis for Pre-test & post-test, control group design

Hi, I am running an analysis for a experimental study and would like to get some opinions about the most appropriate method. I have two groups: control (no treatment) and experimental groups (intervention) I test all individuals before the experiment and after (pretest-posttest) I collect 10...
7. ### Is the difference between two groups bigger, then x2 value bigger and p value smaller?

For chi-square test or other tests involving x2 and p value, is it true that if the difference between two groups is bigger, then x2 value is bigger and p value is smaller?
8. ### How to test the variability of count data over time

I'm wondering how I might best test for over-dispersion of raw count data over time. I have just started a project and am exploring my data, so I do not have a model to test on. I have 4000 independent customers and the frequency of their purchases per day for 44 days. I must determine whether...
9. ### Paired t test unequal sample sizes?

I want to find if there's a significance between the two levels average mean values from my dependent variable "X," which are "High X" and "Low X." High X (85 items) + Low X (65 items) = X (150 items) Both have unequal sample size, but they're from the same group "X." I opted for paired sample...
10. ### How to set up the data for GEE analysis?

Hello, I have 9 feelings and I want to measure if there is a correlation between these feelings across 4 devices. For example, device A had a more "happy" feeling than device C. Originally, they are four questions (each device has its own multiple-choice feelings), therefore, the number of...
11. ### SPSS - Using mixed univariate ANOVA (UNIANOVA) or mixed linear regression (MIXED) instead of repeated-measures ANOVA

Which process is better for using instead of Repeated-Measures ANOVA (SPSS syntax: GLM -- GUI command: Analyze --> General Linear Model --> Repeated Measures)? and Why? (1) Mixed univariate ANOVA (SPSS syntax: "UNIANOVA" -- GUI command: Analyze --> General Linear Model --> Univariate) (2)...
12. ### Mediation - Mediation and b path not significant, can I conclude that there is no relationship between the mediator and the dependent var?

Hi all, I have conducted a mediation analysis with Hayes PROCESS model 4. The overall mediation was not significant. Now, I am wondering the following: If the mediation and the b path within the mediation are not significant, can I conclude that there is no relationship between the mediator...

Hello! I'm a total beginner in SPSS, first time user. I'm having an issue with a survey I'm conducting, I've changed string > numeric using recode. Answers were on the Likert scale and changed to 1-5. However, I've noticed that when I go into analyzing process, the answers for the each...
15. ### Which test to use? one predictor variable and 3 dependent variables

Hello, I'm hoping someone can help me. I am conducting research for my thesis looking at relationship between social connectedness (IV), and diabetes distress, diabetes self-management and perceived competence (DVs). All are continuous variables measured on self-report likert scale...
16. ### Multiple Linear Regression Assumptions

Hi guys! I am gonna model multiple linear regression. Do you think that normality of residuals assumption is met according to the P-P plot? Also, consider the homoscadasticity assumption according to the scatter please. I am writing my Bsc. thesis, what should I do if these two assumptions...
17. ### Moderating Effect (Interaction) in Binary Logistic Regression

Hey, I presume the answer to my question is fairly straightforward but im really having a hard time understanding how to approach this. I am conducting a binary logistic regression with dependent variable Conversion (0 = No, 1 = Yes) and three independent variables; Group (Control vs...

Hi all, I am performing a repeated-measures ANCOVA in SPSS with following characteristics: Dependent variable: weight loss (with three points in time) Independent variable: conscientiousness Covariates: gender, age, depression I can't find a good online guide that will take me step by step...
20. ### Stupid post for a newbie. There is a premade table. How do I know which gender is which number?

It's on the red rectangle. ''Sex = gender''. I saw on a tutorial that if I clicked on Data View and then on Value Labels the numbers of each cell (0 and 1) would turn back to their original ''name'' (female and male). It's not working. How do know who is 0 and who is 1?
