Document Summary
Measures that constitute the results of the study. Variation in them depends on other factors: independent. Variables under the control of the researcher. Object of the study is to find if the independent variables are the related to the variations in the dependant variable two ways of creating through experimental manipulation: creating the variable of change for ex. Did the study measure what it set out to measure three forms: external, internal, construct. Can we generalize the information to real life situations table p. 14. Independent variable really relates to the dependant variable in the manner claimed. If there are any other variables that aid to the difference in dependant variable then there is no internal validity. Sampling selection of participants for research the hope is that the sample is representative of the population you can therefore generalize your findings increases external validity. Once the desired population has been defined ex.
