general statement about what researcher intends to study - purpose of the study - e.g. 'This study aims to investigate the effects of noise on memory'
hypotheses
precise and testable statement that states relationship between variables - operationalisation key part of making statement precise and testable - if findings support hypothesis it can be accepted but if not it must be rejected
non directional hypothesis
two tailed hypothesis - states there will be an effect but doesn't state which way that effect will go - e.g. simply stating there will be a difference between conditions but not saying which group will score higher than which
directional hypothesis
one tailed hypothesis - there will be an effect and states which way that effect will go - e.g. stating one condition will score higher or lower than another condition
use of directional hypothesis
used when past research suggests the findings will go in a particular direction - non directional used when research is unclear or when there's been no previous research in the area
non directional template
There will be a significant difference between (IV1) and (IV2) in terms of (DV)
directional hypothesis template
Participants that (IV1) will (do DV) significantly (more/less/slower/faster/higher/lower) than participants that (IV2)
