Term
 Research design
Definition
 Independent groupsRepeated measuresCounterbalancingMatched pairs
Term
 Independent Groups
Definition
 Participants less likely to work out aim of study.Need more participants.Not as much control of confounding variables.
Term
 Repeated measures
Definition
 Fewer participantsMore control of confounding variablesMore 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 dataOrdinal = categorical dataInterval = continuous dataRatio = continuous data
Term
 Nominal
Definition
 Mutually exclusive categoriesNo magnitude(Male/female)
Term
 Ordinal
Definition
 Ranking in order of magnitudeInterval between units not always equal(8th/bronze, silver, gold)
Term
 Interval
Definition
 Has magnitude No absolute zero(temperature/ date)
Term
 Ratio
Definition
 Highest level of measurementmagnitude, equal interval and absolute zero(weight/height/number of books)
Term
 Correlation
Definition
 Look at relationship between 2 variables
Term
 Regression
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 variableCorrelation Co-efficient: a measure of the relationship between variables
Term
 Correlation coefficient:
Definition
 Measure of strength of relationships, (either spearmans or pearsons) -1 and +1 (0=no correlation)
Term
 Strength of correlation
Definition
 R=top number on leftsig= middle on left
