Document Summary
Types of research - epidemiological: epidemiological research. Attempts to determine whether relationships exist between two variables. I. e. , between diet and cancer, or physical activity and heart disease. Very useful research but a relationship does not necessarily mean one is causing the other - only that they are somehow related: a. retrospective epidemiological study (study past behaviour) These data might be obtained by interviewing or having individuals fill out a questionnaire: b. Does food intake during the 4th-5th decade of life affect the subsequent development of heart disease in the 50"s. Types of research - experimental: experimental research. Involves intervention - this is necessary to determine whether a cause/effect relationship exists. A potential cause (independent variable) is manipulated and the effects (dependant variable) are studied. Independent variable on the horizontal axis is the cause, and dependent variable on the vertical axis is the effect.
