Aims And Hypothesis Flashcards
Aim
A clearly erased general statement about what the investigator intends to research
Hypothesis
A precise testable statement including levels of the IV and dv
Operationalisation
Operationalised variables are stated demonstrated exactly how they are to be measured
Null hypothesis
States there is no change in the measurement of the DV as a result of the change of the IV
Alternative hypothesis
That there is a change in the measurement of the dependable as a result of the manipulation and IV
-alternative hypothesis can be written as either a direction hypothesis also known as one tailed hypothesis or a nondirectional hypothesis also known as a detailed hypothesis
Hypothesis testing
Data is collected and statistical testing is conducting on the data. This provides evidence if the evidence is strong enough to no hypothesis can be rejected and the alternate hypothesis is accepted.
Non-directional hypothesis
States that there is a difference in the measurement of the dependent variable (as a result of the change of the IV). But not the direction the results will go.
E.g. There is a difference in the number of words recorded by participants recalling in greenlight compared to the participants recalling in blue light.
Directional hypothesis
States that there is a difference in the measurement of the dependent variable(as a result of the change of the IV) and says which direction the results will go
e.g. There is an increase in the number of words recall by participants recalling the greenlight competitive participants in blue light
Prove [bonus fact ]
Falsifiability: Any even while establish theories back up with a significant amount of pride evidence have to be open to the possibility that new research will emerge that contradicts its basic principle. The more theory is able to understand attempts of falsify the greater confident we have in the theory but our confidence can never reach 100% certainty
Never used to the prove , but however state the evidence supports
