Psych As A Science Flashcards
What’s Alternative hypothesis
Predicting there will be a relationship between the variables
What’s one tailed (Directional) hypothesis
Predicting the direction of the relationship between variables(Whether the IV will increase or decrease the DV)
Two tailed (non directional) hypothesis
Predicting how one variable will be related to another
Null hypothesis
Predicts there’s no relationship/correlation between variables
Could be due to chance
What’s a scientific method
Process of developing knowledge in one of the 2 specific ways ; induction and deduction
What’s induction
Observations of real world phenomena lead to analysis of patterns that can be seen. Generalisations from those patterns lead to the development of testable hypotheses which can be used to build a theory.
What’s deduction ?
Observations lead directly to the generalisation of theories from which testable hypotheses are developed- these are used to make predictions which are tested by observations
What’s falsification
Evidence that demonstrates that something is not the case(hypothesis is false)
