Be able to:Identify independent, dependent and control variables1.Independent variable (X):represent the cause of an effect (i.e. education)2.Dependent variable (Y):represent the effect (i.e. tolerance)Identify levels of measurementIdentify spurious, additive, and interactive relationships1.Spurious relationship: a relationship that doesn’t actually doesn’t exist but it looks like it does -- the relationship between X and Y disappears when controlling for Z2.Additive relationship:X works together with Z to produce Y -- the direction and strength of the relationship between X and Y is the SAME or VERY SIMILAR at all values of the control variable3.Interaction relationship:the relationship between X and Y IS DIFFERENT across values of Z (control variable)Construct and interpret a frequency distributionConstruct and interpret a crosstab●She may give us a half completed chart and we fill out the rest ●Independent variable is on top in a crosstab ●Know how to calculate the percentagesConstruct and interpret a means comparison●She will gives us the linesCalculate and know when to use each measure of central tendency____________________________________________________________________________●Fill in the blanks, short answers (i.e. is this relationship additive, spurious, etc.), multiple choice●Based on what we have covered so far●BRING CALCULATOR (i.e. find the median)●May be asked to interpret data (i.e. charts or graphs)○Cross tabs, means comparison●Know if a variable is at the nominal, ordinal, or interval level●Zero order relationship: no control -- it’s just an X and Y
●Be prepared to calculate partial effect●Whatever she taught us how to do in class, we have to know for the exam
As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
