Intro to Psyc

Question 1

quasi-experimental study

Answer 1

a study in which random assignments to conditions is not used. Instead, we rely on existing group memberships.

Question 2

Outcome Variable

Answer 2

Dependent Variable

Question 3

Predictor Variable

Answer 3

Independent variable

Question 4

External Validity

Answer 4

the extent to which the results of studies can be generalized to the real world
-can’t have validity without reliability
-accuracy (chem)

Question 5

Directionality Problem

Answer 5

correlational studies only allow us to determine whether these is an association between two variables, but not whether one of the variables being measures is actually causing the noted changes in the other variable

Question 6

Spurious correlations

Answer 6

Situations in which two or more variables appear causally connected, but their association is purely random
-(only correlational studies)

Question 7

COnfounding Variables

Answer 7

variables that researchers are not purposely studying (not the predictor variable or outcome variable) that unexpectedly influence both the predictor value and the outcome variable, and therefore undermines our ability to draw causal conclusions from a study

Question 7

subject reactivity

Question 8

Reliability

Answer 8

the ability to yield the same results each time
-Is the measure consistent?
-precision (chem)
