Week 3 Correlational Design Tree

Question 1

When exploring the degree of relationship among the variables in research questions, what is the goal of analysis when there is 1 (continuous) DV?

Answer 1

The goal of analysis when there is one continuous DV is to create a linear combination of the IV’s to optimally predict the DV

Question 2

Which analytic strategy would you chose when there is 1 x (Continuous) DV & 1 IV?
and again, with multiple (Continuous) IV’s & no Covariates?
and again with multiple (continuous) IV’s & some covariates?

Answer 2

1 x DV & 1 x IV = Bivariate r

1 x DV & multiple IV = Multiple Regression

1 x DV & Multiple IV & some Covariates = Sequential Multiple Regression

Question 3

When exploring the degree of relationship among the variables in research questions, what is the goal of analysis when there are multiple (continuous) DV’s?

Answer 3

The goal of analysis when there are multiple continuous DV’s is to maximally correlate a linear combination of the DV’s with a linear combination of the IV’s

Question 4

Which analytic strategy would you chose when there are multiple (Continuous) DV’s & Multiple Continuous IV’s?

Answer 4

Multiple DV’s & Multiple IV’s = Canonical Correlational Regression

Question 5

When exploring the degree of relationship among the variables in research questions, what is the goal of analysis when there is one (may be repeated measures) DV & Multiple IV’s (continuous & discrete), with cases and IV’s nested?

Answer 5

The goal of analysis when there is one (may be repeated measures) DV is to create linear combinations of the DV’s & IV’s at one level to serve as DV’s at another level

Question 6

Which analytic strategy would you chose when there is one (may be repeated measures) DV & Multiple IV’s (continuous & discrete), with cases and IV’s nested?

Answer 6

1 x DV (may be repeated) & Multiple Continuous IV’s = Multilevel Modelling

Question 7

When exploring the degree of relationship among the variables in research questions, what is the goal of analysis when there are no DV’s and Multiple (discrete) IV’s?

Answer 7

The goal of analysis when there are no DV’s and Multiple (discrete) IV’s is to create a log-linear combination of IV’s to optimally predict category frequencies

Question 8

Which analytic strategy would you chose whenthere are no DV’s and Multiple (discrete) IV’s?

Answer 8

0 x DV & multiple (Discrete) IV’s = Multiway Frequency Analysis
