Research Methods

• Alternative hypothesis - the hypothesis the researcher tests by conducting a study and colleting data, which attempts to show the null hypothesis is not supported.
• Condition - an experiment is usually organised so there are 2 trials, after which the performances of the participants are compared; these are the conditions of the experiment
• Dependent Variable - the factor which will be measured in an experiment to see if changing the IV has had an effect
• Experiment - a research method in which the researcher tries to control all the variables other than the independent variable and dependent variable; this allows the researcher to identify a cause-and-effect relationship between the IV and the DV
