Document Summary
Lecture 2 / chapter 4 nature of quantitative research. Broad terms quantitative research entails a collection of numerical data, deductive relationship between theory and research and an objectivist conception. Measurement would be hard to understand phenomena, make sense of theories without acquiring data on them interested in looking at relationships between variables, strength of it, etc. Establishing causality exploring how relationship of one variable changing impacts another variable. Probability sampling eliminates bias by using a random selection process to improve chances of representative sample. Concern with generalizability strong among quantitative researchers used cross-sectional and longitudinal research designs. Eliminate routine errors, should be able to replicate other scientist"s research. If researcher"s values affect their findings, not replicable more likely in social sciences than natural sciences. Low incidence of publications in social science of replicability not high status, difficulty of ensuring conditions are exactly like the original study: important that methods used in original study are made explicit so replication is possible.
