Quantitative Research

What this unit covers

The page lists resources on the core ideas of quantitative research. Mind maps lead the way, and they work through variables, scales of measurement, validity and reliability. One map explains variables as the factors you are interested in, and another separates categorical from continuous variables, from nominal and ordinal to binary scales.

Where to start

Begin with the mind map on variables, scales of measurement, validity and reliability, since later ideas depend on it. Then move to the map on sampling, data collection and measurement. Its learning objectives cover what sampling is, why it is necessary, and the difference between probability and non-probability methods. The Study population map follows well, with target and accessible populations, generalisability, and internal and external validity.

Data collection and its problems

Quantitive Data Collation looks at how study design and the research question shape the data you gather, from records and case series to questionnaires. The map on potential problems with physiological and clinical data collection covers physiological variation, variation in the measuring instrument and observer variation. The Reliability and Validity map defines a dependable, stable and consistent instrument.

Designs and revision tools

For designs, there are flashcards on correlational research designs, a map on causal-comparative research, and one on associative claims and correlations. The flashcard deck Quantitative Research and Sampling asks what quantitative research is, how it differs from qualitative work, and what the types of surveying are. Quizzes such as Quantitative Research Methods Quiz let you check what stuck.

How to use maps and quizzes together

Read a map first, then take a quiz and note the questions you miss. Return to the matching map for those gaps. This unit sits in the Research Approaches and Fields strand of Research methods and academic skills. Teachers can use the maps as ready-made starting points for a class.
