1. ### Measuring categorical (race) and two continuous varibles

I need your help to identify which test I have to implement for measuring the correlation of one categorical and two continuous variables. In my study I have two constructs: 1- information consumption from credible sources (CS)--4 items(ie., information consumption from CDC website) 2-...
2. ### Polynomial (quadratic) contrasts: clarifications & inverted-U

Hello everyone, I am trying to see how the motor time of a response to a stimulus (DV: quantitative, continuous) evolves based on difficulty level of the task (IV: 8 levels, categorical). My hypothesis is that motor time will increase, then decrease (inverted U shape). I conducted a RM ANOVA...
3. ### Assumptions for a 2 x 2 repeated-measures ANOVA

I am currently working on a 2 x 2 repeated-measures ANOVA (rmANOVA), and I am unsure as to which assumptions I need to investigate and how to investigate them. It's a behavioral experiment. I have 30 subjects and 4 (2 x 2) measurements from each of them. There are equal sample sizes (30) in each...
4. ### Repeated measures explained?

Hello, I need some help with the analysis of repeated measures ANOVA. I have a variable measured at 9 different time points. When I do the repeated measures a pairwise comparison comes out with different p values. Is there a way to graphically represent the statistical significance at each time...
5. ### Can I use an ANOVA?

Hi everyone, I’m doing an assignment where I was training my dog to sit. I want to compare 4 different levels (baseline, calm environments, excited environments & all environments) the last 3 levels had primary reinforcement and the baseline did not. I did a FR1-FR3 for 2 levels and VR5 for the...
6. ### Question about 3X3 repeated measures ANOVA and simple effects

First time posting here. I have conducted a transcranial magnetic stimulation study and am analyzing the results as a 3x3 repeated measures ANOVA. I'm a grad student in cognitive psychology. 1. purpose of the study: to dissociate language from other forms of cognition using TMS. 2...
7. ### How to compare 2 groups where 1 has repeated measures

Hello, I have three groups: healthy controls, pre-surgery, and post-surgery. The pre and post-surgery are the same patients who participated in the study before and 10 months after their operations. The healthy controls were matched to the patient group based on anthropometrics. My issue is...

9. ### Systat13 / Problem with plot of Residuals vs Predicted values - repeated measureANOVA

Hi there, I’m trying to do 2 analysis from one set of data. - 1st analysis: repeated measure ANOVA with 1 grouping factor (TRAIT\$) and 1 within factor (TIME). a/ I used the ANOVA procedure. To check the conditions of normality and variance equality for the ANOVA: can I use ‘only’ the...
10. ### Questions on data complexity beyond my stats knowledge: what stats tests to use?

Hi everyone, sorry for this long post. I tried to be detailed, but if anything is unclear, please let me know. I consulted two stats friends for help but neither was familiar with the type of experimental design described below. Thank you for your time and expertise in advance. I'd deeply...
11. ### Mixed Repeated Measures and Independent Measures One-Way ANOVA [SPSS]

Hello, I am trying to determine the best way to carry out my one-way ANOVA in SPSS. I have three groups: Pre-Surgery, Post-Surgery, and Control. Technically, the Pre- and Post-Surgery groups are repeated measures but the comparison to the control would be independent. How would I go...

Hey everyone, I've been trying to confirm this for a while but I haven't been able to find a conclusive answer. I'm guessing the answer is pretty simple but I'm a bit rusty and I've looked over it so many times that I'm now a little bit saturated. Basically I am doing a project on bladder...
13. ### Non significant results from one way repeated measures ANOVAs - what now?

I am currently writing my thesis for an MSc in Sport Performance. My data collection involved running my participants through 5 different warm-up protocols (including baseline) and testing them in 3 different ways - stride to sprint times, jog to sprint times and agility times. I ran three...
14. ### multiple measurements per condition for a repeated measures ANOVA

I want to know whether I can use the repeated measures ANOVA for my analysis - I collected from 1 to 6 data points per condition from each of 13 subjects and wonder if I can average the measurements under each condition (the measurements were taken one right after the other to make sure the...
15. ### What to do with unequal sample sizes?

I am working on this time-effect project in which we pulled data at different time points from a big old data set. The issue is that all subjects were sacrificed at different times after treatment. So I have 16 samples at time 1, 10 samples at time 2, and so on. I am going to do Friedman test...
16. ### Comparing Treatments for Spinal Cord Injury

Hi Guys. First post in this forum (actually, in any statistics forum). I am not from an English speaking country, so you may find some grammatical errors. Here’s my problem. I’ve tried to search in a lot of places and cant find a specific answer for this question: I’m a physician and I...
17. ### Stream temperature over time: is a repeated measures ANOVA my best bet?

I am trying to analyze temperature data across 5 sites taken over approximately 4 months and am having trouble working out the best test to use (I'm out-of-practise with stats!). The data: Five temperature data loggers were set out along a river. Three were spaced along tributary A, one...
18. ### Repeated measures ANOVA vs. Mixed Models

Hi, I'm trying to analyze the results of my Master Thesis with SPSS. I've 3 experimental conditions (factor: Group) and for variable A every subject in each condition has 2 expressions (factor: Hemisphere). I want to test the effects of these 2 factors on my dependent variable A. What I...
19. ### I need to test within and between factors at the same time. Which test should I use?

Hi everyone, I'm trying to analyze the results of my Master Thesis with SPSS. I've 3 experimental conditions (factor: Group) and every subject in each condition has 2 expressions (factor: Hemisphere). I want to test the effects of these 2 factors on my dependent variable A. What I would like...
20. ### Paired Samples T test or Repeated Measures ANOVA?

Hi everyone, I am on a tight deadline and could use some input on my proposed analyses for my project. PROJECT: I am administering a novel treatment to participants and seeing if they lose weight at the end of 6 months of treatment. There is no control group (there are rationale for this...
