– Potential for testing
DESIGNING THE RESEARCH STUDY
• The “blueprint” for your study
– Determining your sample
– Deciding how, where, and when data are to be collected
COLLECTING THE DATA
• Three features that are key to quantitative studies
– All variables must be measurable
– All data collection procedures must be objective
– All data collection procedures must be able to be duplicated (replicable)
ANALYZING AND INTERPRETING THE DATA
• Two major types of analysis in quantitative research studies
– Descriptive statistics
– Inferential statistics
Descriptive Statistics
• Statistics used to describe a study’s sample or population
• Common descriptive statistics
– % percentages (e.g., 52% female, 48% male)
– Average (e.g., mean age of BSW...
