    Qualifiers, Factor Analysis and Regression

    I'm working on a project that wants me to do factor analyses that generate an IV. Basically some groups of questions and no IV. And I'm told the IV will be generated by the FA. Any ideas? Then I'm supposed to put the questions into a regression model. Somehow I can put the outcome of the FA into...

    Graph with multiple IV's.

    Hello Forum, I would like to learn how to construct a line graph on SPSS with a few variables on the Y axis. I could not find the solution online. I don't even think it's doable. Is it? Thanks.

    Which test to use?

    What I want to have is this: The effect of 1 continuous variable ("fixed factor"?) on a categorical DV controlling for 1 categorical variable (covariate) and 4 continuous variables (covariate). I can also work with the continuous variables transformed into categorical variables. Isn't this...

    Binary Logistic Regression Questions

    I have a few questions about binary logistic regression. A-I have 1 categorical DV (2 level). B-I have 1 categorical covariate (2 level) programmed as a categorical variable in the "Categorical" options in he regression window. That "indicator" and "Reference Category" stuff, which I'm not...

    ANCOVA results & covariate confusion

    This is a bit hard to explain so please bear with me till the end. Thanks for the effort. I have 5 IV's and 1 DV. I'm trying to find how much each IV influences the DV. I run 5 ANCOVA's. In each of them I have one of the IV's as an IV, and the other 4 IV's as covariates b/c the 5 IV's are all...

    Can the IV in an ANCOVA be continuous?

    While controlling for a few categorical and continuous variables. All I care about is the effect of the IV, whether it is significant or not. Thanks for the responses, in advance.

    Reporting ANCOVA results. - Where are Between/Within Groups dF's?

    So I know it goes something like F(2,54) = 4.45, p<0,05 but where are the numbers inside the parantheses of the F? F(between groups dF, within groups df).. Where are these numbers on the output of the SPSS? thnx.

    When to control for a variable?

    Hi. I'm trying to analyze the relationship between child abuse and personality disorders. I have two scales which have their own subscales, all on ratio scales/basis. I am doing many different tests and analyses. My question is: should I confound for gender? In my data gender was not associated...

    Another confounding question. -ANCOVA and perhaps Regression

    Hi. I'm trying to analyze the relationship between child abuse and personality disorders. I have two scales which have their own subscales, continious variables. I want to research the relationship of different types of child abuse (emotional, physical, and sexual abuse and neglect) on 15...

    ANOVA Posthoc: Any way I can do posthoc with groups of less than 2 people?

    Hi. As the title says, I'm trying to run a post-hoc (I am accustomed to using Tukey, I don't know why) for a one-way-ANOVA, but I have about 10 groups and I think 2 of the groups has 1 people, and 2 groups have 2 people in it, each. So SPSS doesn't let me do it. It says: "... because at least...

    Logistic Regression Interpretation help

    Hi. I have two variables which I want to find the correlation coefficient of. One of them is ordinal the other interval, so I used logistic regression. I want to present the strength of this relationship next to another relationship(basic pearson correlation) so I just want the r reported. Does...

    Comparing results of two different tests measuring correlational relationship?

    Hear this. I have three scales Scale A, B, and C. I want to compare the strength of relationship between Scale A and B, and between Scale B and C. Details: Scale A: Actually, this is not a scale. This is just 1 question with 4 nominal answers. What type of family do you have? Authoritarian...

    So I have another hypothesis I want to design: My IV is scores from an right wing authoritarianism scale. Possible scores for a person range from 0 to 180. No decimals(Does it matter?). My DV is where the person states s/he resides on a political spectrum ranging from -4(left) to +4(right). I...
