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?
2. ### 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...
3. ### 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...
4. ### 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...
5. ### 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)...
6. ### 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...

9. ### 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...
10. ### 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...

15. ### Running Logistic Regression with Random Effects in SPSS (not Multilevel)

HI! I'm really confused with how to run my logistic regression model (I have a dichotomous dependent and 8 nominal cat/continuous independent variables), I also have 3 separate random variables which I want to include in the model. I've looked at mixed model analysis but it's not a multilevel...
