Research Methods Flashcards
Methods: EXPERIMENTS (2)
Labatory Experiments
Field Experiments
Methods: HYPOTHESES (4)
Directional
Non-Directional
Null
Alternative/ Experimental
Methods: OPERATIONALISATION
Narrowing and specifying exactly what will be tested/ recorded
Methods: EXPERIMENTAL VARIABLES (5)
Extraneous
Confounding
Situational
Participant
Experimenter
Methods: EXPERIMENTAL CONTROL (3)
Standardisation
Double Blind
Single Blind
Experimental Design: INDEPENDENT GROUPS DESIGN (3)
Different pps take part in each condition
Strengths: no order effects (demand characteristics) e.g. fatigue or practice effects
Weaknesses: individual differences, more people (cost, time)
Experimental Design: REPEATED MEASURES DESIGN (3)
Each pps takes part in each condition
Strengths: less people
Weaknesses: order effects (demand characteristics) e.g. fatigue or practice effects
Experimental Design: MATCHED PAIRS DESIGN (3)
Pairs of pps matched on appropriate variables relevant to experiment
Strengths: minimise individual differences, no order effects
Weaknesses: time, cost, effort, still some individual differences
Improving Reliability (3)
Split Half Method
Test-retest Method
Inter-rater Reliability
Improving Validity (4)
Construct Validity
Predictive Validity
Population Validity
Ecological Validity
