Psychology Research Methods (Validity/Reliability and Experimental Design) Flashcards
Validity
Accuracy
Reliability
Precision
Cronbach’s Alpha
Statistical Correlation
Experimental Designs
Controlled and experimental independent variables affecting dependent variable
Confounding Variables
Random Situations
Procedual Variables
More differences between controlled and experimental variables
Operational Variable
Manipulation irrelevant variables
Individual Difference
Individual differentiation, recommended to equal out characteristics in both controlled and experimental variables
Repeated Measure Design
Same group of participants being tested multiple times
Generalisation
results from a experimental group and trying to connect with larger groups
Representative Sample
Extracted group of participants from larger groups
External Validity
How accurate the results are outside of the experimental group
Random Selection
Randomly picking participants for the experiment
Quasi-Random
Random picking participants which their own characteristics don’t affect the results
Convergent Validity
Positive/negative data correlations
Discriminant Validity
Negative correlation, accuracy decreased
Content Validity
How relevant the results are to the main construct
Predictive Validity
Predicting dependent and independent variables interchangeably (IV affecting DV and DV affecting IV)
