Term
Types of experimental design 

Definition
Independent groups Repeated measures Matched pairs 


Term

Definition
Independent groups Repeated measures Counterbalancing Matched pairs 


Term

Definition
Participants less likely to work out aim of study. Need more participants. Not as much control of confounding variables. 


Term

Definition
Fewer participants More control of confounding variables More likely to guess aim 


Term
Counterbalancing (assigning order to groups) 

Definition
Matched pairs (each member of pairs to separate groups) 


Term
Levels of measurement (differ in terms of magnitude, absolute zero and equal intervals) 

Definition
Nominal = categorical data Ordinal = categorical data Interval = continuous data Ratio = continuous data

Term

Definition
Ranking in order of magnitude Interval between units not always equal (8th/bronze, silver, gold) 


Term

Term

Definition
Look at relationship between 2 variables 


Term

Definition
Predict one variable from another 


Term
Correlation: Are 2 variables related? 

Definition
Does one increase as the other increases? Does one decrease as the other increases? 


Term
Correlation: How can we get a numerical measure of the degree of relationship? 

Definition
Correlation: relationship between variable Correlation Coefficient: a measure of the relationship between variables 


Term
