KNES 469 Lecture Notes - Lecture 4: Cohort Study, Data Analysis, Meta-Analysis
Document Summary
Key: the procedures should be presented with such detail and clarity that another researcher could replicate the study if desired. For experimental studies, this section should also include a description of the research design. All experimental procedures need to be thoroughly described. Descriptive: investigator attempts to describe a group of individuals on a set of characteristics. Exploratory: investigator examines a variable of interest and explores its dimensions, including how it relates to other factors. Proven relationships between the variable and other factors can lead to predictive models. Correlational studies, cohort studies, case control, secondary analysis of existing data sets. Experimental: provides a basis for comparing 2 or more conditions. Controls or accounts for the effects of extraneous variables, providing the highest degree of confidence in the validity of outcomes. Enables the researcher to draw meaningful conclusions about observed differences. Randomized controlled trials, sequential clinical trials, evaluation research, quasi-experimental research, meta-analysis.
