- types of variables and hypothesis
- independent variable
- variable the experimenter manipulates
- eg trying to find out what energy drink makes people run faster red bull/monster, then make them run 100 m
- variable the experimenter manipulates
- Dependant variable
- variable that experimenter measures
- IV- what type of drink (RB/M) DV-how long it took them to run 100m
- variable that experimenter measures
- null hypothesis
- hypothesis that predicts no outcome
- "there will be no significant difference"
- hypothesis that predicts no outcome
- directional hypothesis
- predicts which of 2 conditions will result in a greater change in the DV
- "there will be a significant difference" (in what the q says)- specific
- predicts which of 2 conditions will result in a greater change in the DV
- non-directional hypothesis
- predict IV will have an effect on DV but direction of effect is not specified
- "eating chocolate affects memory"
- predict IV will have an effect on DV but direction of effect is not specified
- correlation
- is a relationship- researchers look at whether one variable effects another, neither have been manipulated
- independent variable
