1. ### 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...
2. ### 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...
3. ### Use OR conditional statement using the MISSING function (SPSS)

I want to use an OR conditional statement using the MISSING function in SPSS (see below), but it doesn't work like this. Anyone knows how I can code this correctly? COMPUTE inclOndrzGeweig=1. IF (MISSING(geslacht | Leeftijd | RSES1_T0 | RSES2_T0 | RSES3_T0 | RSES4_T0 | RSES5_T0 | RSES6_T0 |...
4. ### Repeated-measures ANCOVA - Handle assumptions and missing data (SPSS)

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...
5. ### 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?
6. ### 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...
7. ### Clustered bar graphs

Hi! Could anyone explain how I create such clustered bar graphs in SPSS? I want the clusters divided by interactions and I want to show the mean (+errorbars) of each of the three variables (advice-only, dialog history, empathy). Probably I need to put the interactions on the y-axis (?!) but...
8. ### SPSS - ANOVA test and & Post Hoc

Hi, I have conducted both ANOVA along with Post Hoc Test on SPSS. However, I have encountered a problem on the Post Hoc Tests. In particular, between the multiple comparisons and homogeneous subsets sections. My problem is under the multiple comparisons - the category 7 is not statically...
9. ### Latent Class Analysis - How to identify the main drivers?

Hi All! I ran a LCA to identify the best possible segmentation of classes in a population. I used Latent Gold for this and imported the clusters later in to SPSS for some comparisons and calculation. I am a bit stuck with the following questions: Are there any metrics which indicate which of...
10. ### What statistical analysis and how?

Hello everyone, I am studying the effects of framing on food neophobia and the purchase likelihood of novel foods. Currently, I have made a pre-test where I have 4 conditions and 1 control condition where they are pictures with messages framed a certain way (emotion-promotion...
11. ### Multiple Imputation in SPSS: What to do and report

Hi everyone :) I'm currently working on a research question where there are 2 categorical predictor variables (one with 2 levels between subjects, the other with 7 levels within subjects) and one continuous response variable. I want to conduct a simple repeated measures ANOVA in SPSS. The...

13. ### Power analysis for moderated mediation (and a small research design question)

Hello guys! I am doing research on the effect of a specific medicine, quantified by dosage, on specific feelings (to be called; SF), mediated by feelings of connectedness, in which the relationship between the medicine and SF (X - Y) ánd the relationship between medicine and connectedness (X -...
14. ### How to Analyze Continuous IV and DV?

I'm a relative novice at statistics and would appreciate some help with a dataset I'm trying to crunch. I'm currently looking at factors that predict increasing utilization of healthcare resources following surgery in a set of 130+ patients. Some of the independent variables I'm looking at...
15. ### Limits of agreement and Bland Altman plot

May I kindly ask how may I present the Bland Altman plot in words in the “Results” section of the manuscript, e.g. what should be reported and how may I find these in SPSS? Thanks a lot!
16. ### Moderation: what if one predictor variable affects another?

Hi guys! We would be very thankful for some insight on our moderation analysis. We have two predictor variables, one is manipulated, the other is measured. There’s a measured outcome variable. We would like to do a moderation analysis where the measured predictor variable moderates the effect...
17. ### Which test should I use? Dichotomous independent + numeric dependent

Hi everyone! I am in doubt about which test I should conduct. My indepent variable is dichotomous: values 0 = no presence of female combatants in conflict and 1= presence of female combatants in conflict). So indepent variable is eiter no/ yes My dependent variable is the duration of conflict...
18. ### Selection of the correct covariance structure – linear mixed model in SPSS

Hi together, I am currently trying to build a linear mixed model with repeated measurements in SPSS. I would expect that the correlation between my measurements is highest at adjacent time points, so my guess was that AR1 (autoregressive structure) is the right covariance structure in my case...
19. ### Multiple Linear Regression

Hello, I am an MBA student and require help doing a multiple linear regression analysis using spss, check if I uploaded the data with the correct options and how to interpret the data and results. I have 2 independent variables and 1 dependent variable. Thanks!
20. ### Questions concerning the analysis of my Data

Hello everyone, I received some old data that I am now supposed to analyze, however, deciding for an appropriate statistical test turned out to be a little hard for me, so I could Need your help! The data are basically from a 2x2 factorial design with Pre- and Posttest measures. It is an...
