Flashcards in Research Methods Deck (16):
Involves the manipulation of an independent variable to measure the effect on the dependent variable. Experiments may be lab, field, natural or quasi.
A general statement of what the researcher intends to investigate; the purpose of the study.
A clear, precise, testable statement that states the relationship between the variables to be investigate. Stated at the start of any study.
States the direction of the difference or relationship.
Does not state the direction
Amy thing that can vary or charge within an investigation. Variables are generally used in experiments to determine if changes in one thing result in changes to another.
Some aspect of the experimental situation that is manipulated by the researcher- or changes naturally - so the effect on the DV can be measured.
The variable that is measured by the researcher. Any effect on the DV should be caused by the change in the IV.
Clearly defining variables in terms of how they can be measured
Any variable, other than the IV, that may have an effect on the dependent variable if it is not controlled.
Any variable, other than the IV, that may have affected the DV so we cannot be sure of the true source of changes to the DV.
Any cue from the researcher or from the research situation that may be interpreted by participants as revealing the purpose of the investigation resulting in a change in behaviour.
Any effect of the investigators behaviour on the research outcome. This may include everything from the design of the study to the selection of it.
The use of chance in order to control for the effects of his when designing materials and deciding the order of conditions
Using exactly the same formalised procedures and instructions for all participants in a research study
