Dependent Variable -a variable that varies due, at least in part, to the impact of the independent variable. In other words, its value “depends” on the value of the independent variable.
Independent Variable - the conditions of an experiment that are systematically manipulated by the researcher. A variable that is not impacted by the dependent variable, and that itself impacts the dependent variable.
Methods - systematic approaches to the conduct of an operation or process. It includes steps of the procedure, application of techniques, systems of reasoning or analysis, and the modes of inquiry employed by a discipline.
Null Hypothesis - the proposition, to be tested statistically, that the experimental intervention has "no effect," meaning that the treatment and control groups will not differ as a result of the intervention. Investigators usually hope that the data will demonstrate some effect from the intervention, thus allowing the investigator to reject the null hypothesis.
Standard Deviation - a measure of variation that indicates the typical distance between the scores of a distribution and the mean; it is determined by taking the square root of the average of the squared deviations in a given distribution. It can be used to indicate the proportion of data within certain ranges of scale values when the distribution conforms closely to the normal curve.
