9.aims and hypotheses Flashcards
what is an aim
developed before designing and carrying out the research
general statement which outlines what is being investigated
not plucked out of nowhere
developed from a previous theory
what is a hypotheses
formulated once an aim has been decided
specific prediction about the outcome of the investigation, tested in the study
used with a non-experimental method
what is a null hypothesis
constructed without support/evidence
need to have a conclusion for what the results show
states no difference/correlation
what is an experimental hypothesis
used when an experimental method has been carried out and there is an IV and DV
directional hypothesis
predicts the direction of the results
eg one condition has a more/less/faster/slower effect on the DV
used when there is a lot of previous research into the area so the researcher can make an informed prediction
non-directional hypothesis
less specific than a directional hypothesis
doesn’t predict the direction of the results
used when investigating an arrea with little existing research
