I've been asked to validate a model created by someone else and need some help on how the final score is calculated. Have put lots of detail; apologies for the post length. The output (dependent) variable is ordinal scale with 5 points (i.e. 1-5) representing an assessment of risk (not risky...
2. ### Factors or covariates in multinomial logistic regression

I have ordinal variables where I ask the respondent to rate how frequent they go for a motivational talk ( 1: never, 2: rarely, 3: sometime , 4: often, 5: always ) and also their satisfaction towards their life ( 1: unsatisfied ............ 9:very satisfied) . So, as i know this kind of...

Can I use chi-square test of independence if one variable is nominal and the other is ordinal, or do both have to be nominal?
5. ### Is this an interval variable?

The variable is called "externalizing behaviours" and it has the numbers 9,7,7,3,11,6,2,6,6,9. I assume that the numbers show the amount of externalizing behaviour because the question says it was an observation. Is this interval/ratio? I think it is interval (rather than ordinal) because 7 is...

9. ### SPSS: Which chi-square test should I use for one nominal and one ordinal variable?

My hypothesis is Gender and opinion on smoking is associated. I am using a likert scale (Strongly disagree..strongly agree) for the statement 'Smoking makes you look cool'. In SPSS, I have coded gender as nominal and the opinion as ordinal. I have to use a chi-square test but dont which box...
10. ### measurement level of exponential temperature in degrees Celsius

I was wondering about the following theoretical example. Assume that I have measured temperature in degrees Celsius on various days (x), and for some strange reason converted each of these using e^x. My question is now, what measurement level is this 'exponential temperature'? My own...

16. ### Ordinal variable difference between pre and post- age IV

I have a self-efficacy scale ordinal 1 to 5. I ask this question in pre and post tests. I would like to know if age affect the change in self-efficacy between pre and post. My attempt was to gen efficacy _change= efficacy_post - efficacy_pre. and the just regress efficacy _change age Is...
17. ### Fisher's exact test and non-inferiority / equivalence

I have some data (multiple choice question scores for two groups of medical students exposed to an experimental and standard type of anatomy teaching). It's ordinal data (scores out of 10). I'd like to test whether the experimental type of teaching is equivalent (i.e. not inferior) to the...
