C14 + V9

6 important questions on C14 + V9

What is a Univariate Analysis and what is the purpose?

The analysis of a single variable, for purposes of description. You can’t explain relationships, you can only show results. Example: gender or times a week you go to the gym

Which 3 measure can we use in univariate analyses?


Frequency Central tendency (mean, mode, median)

Dispersion (range, standard deviation and variance)

A) What do we use to measure at the nominal level in Bivariate?
B) What do we use to measure at the nominal level in tri or multivariate analysis?

A) Cross table
B) Elaboration model

What do try to understand by the use of the elaboration model?


The linkage between two variables by controlling for the effects of a third (the test variable)

Give the names of the different types of elaboration models showed in the picture.

1) Direct Effect (Zero-order relationship)
2) Indirect Effect of Z (Interpretation; mediator effect)
3) Spurious Effect (Explanation)
4) Interaction Effect (Specification; moderator effect)

What are the 5 steps in the elaboration model?


  1. Formulate the hypothesis
  2. Draw the conceptual model
  3. Formulate predictions in terms of d%
  4. Check the predictions using cross table analysis
  5. Report conclusion

The question on the page originate from the summary of the following study material:
