Planning and conducting research: Aims and hypotheses Flashcards
Alternative hypothesis for an experiment
There will be a difference between (state one side of IV) and (state the other side of the IV) on (DV) as measured by (state how the DV is being measured specifically)
Null hypothesis for an experiment
There will be no difference between (state one side of IV) and (state the other side of the IV) on (DV) as measured by (state how the DV is being measured specifically). Any difference will be due to chance.
Alternative hypothesis for a correlation
There will be a positive/negative correlation/relationship between (state one variable) and (state the other variable) as measured by (ay how the two variables are being measured specifically).
Null hypothesis for a correlation
There will be a positive/negative correlation/relationship between (state one variable) and (state the other variable) as measured by (ay how the two variables are being measured specifically). Any relationship will be due to chance.
Ethical implications of socially sensitive research
This happens if:
- It is researching a highly personal or private experience
- It is research focused on deviant behaviour
- If the research questions the authority of those in society such as politicians
Null hypothesis
A statement of no relationship between variables
Alternative hypothesis
States a relationship between variables
Operationalise
Refers to how you will define and measure a specific variable as it is used in the study
Alternative hypothesis: One tailed directional hypothesis
Predicts the nature of the effect of the IV on the DV, e.g we predict more or less, an increase or decrease, higher or lower
Alternative hypothesis: A two tailed non-directional hypothesis
Predicts that the IV will have an effect on the DV but the direction of the effect is not specified, e.g we predict a difference, an effect or a change but we don’t know the difference
