I'm stuck in my analyses of my covariables.

Here are the questions I want to test:

What is the influence of educational level on judgments and decisions of participants?

What is the influence of organizational level on judgments and decisions of participants?

What is the influence of emotional intelligence on judgments and decisions of participants?

What is the influence of social / time pressure on judgments and decisions of participants?

I thought of doing an AN(C)OVA.

**Dependent variable =**

applicant credential (or applicant trait importance/ applicant total evaluation (separate analyses for the three different dependent variables).

**Categorical independent variable =**

candidate (western/non western)

experimental condition (both, ethnic prime, person prime, control group)

(Time/social pressure; Is either 1 or 2 (yes and no time pressure (but is this an independent variable or a covariable?))

**Covariables =**

Educational level (continuous)

Organization level (continuous)

Total emotional intelligence score (continuous) (tot_tei)

This is what my syntax has to look like according to my stats teacher :

( my statistics teacher told me I had to put in contrasts (I don’t know what for?? And he put all of the covariables in once)).

UNIANOVA appl_credent BY candidate exp_condition time_pressure WITH edu_level org_level tot_tei

/CONTRAST(candidate)=Polynomial

/CONTRAST(exp_condition)=Helmert

/CONTRAST(time_pressure)=Simple

/METHOD=SSTYPE(3)/INTERCEPT=INCLUDE

/PLOT=PROFILE(exp_condition*candidate*time_pressure) TYPE=LINE ERRORBAR=CI MEANREFERENCE=NOYAXIS=0

/PRINT ETASQ DESCRIPTIVE PARAMETER OPOWER/CRITERIA=ALPHA(.05)

/DESIGN=edu_level org_level tot_tei candidate exp_condition time_pressurecandidate*exp_condition candidate*time_pressure exp_condition*time_pressurecandidate*exp_condition*time_pressure.

Now I am not sure if I have to

- Put all the covariables in the analyses all in once (or first without covariables and then one by one and the last analyses only the signifanct covariables altogether)
- Put “contrasts” in the analyses, since I don’t know what to use that for..
**Where to look in the output**. If I want to find answers for my control variable questions: (e.g. What is the influence of educational level /organizational level /emotional intelligence/ time pressure on judgments and decisions of participants?

I sincerely hope my question and explanation is clear.I’m stuck and I would be so grateful for your help and opinions!!
