Quantitative and Qualitative
• Measuring social phenomena, quantify things, generalize findings = QUANTITATIVE
• Understanding experiences and meanings = QUALITATIVE
• These methods can blend
Types of Quantitative Research
• Exploratory or descriptive
• Explanatory
The Quantitative Research Process
• Select a topic
• Define the problem
• Review the literature
• Formulate a hypothesis
• Choose a research method
• Collect the data
• Analyse the data
• Share the results
Hypothesis
• Statement about variables and the relationship between them
o E.g. children with disability are more at risk of sexual abuse than children
without disability
Variables
• An entity in research that can assume different values
o E.g. gender, age
Data Collection
Data Collection Tools
• Survey questionnaires
• Scales
o E.g. Socioeconomic status scale
Sampling
• process by which research select units from a population
• Population: group being studied
o E.g Lesbian and bisexual women in NSW
• Unit: most primary element of a research study
Population & Sample
Population/Universe
Sample -> Findings

Document Summary
Quantitative and qualitative: measuring social phenomena, quantify things, generalize findings = quantitative, understanding experiences and meanings = qualitative, these methods can blend. Types of quantitative research: exploratory or descriptive, explanatory. The quantitative research process: select a topic, define the problem, review the literature, formulate a hypothesis, choose a research method, collect the data, analyse the data, share the results. Hypothesis: statement about variables and the relationship between them, e. g. children with disability are more at risk of sexual abuse than children without disability. Variables: an entity in research that can assume different values, e. g. gender, age. Data collection tools: survey questionnaires, scales, e. g. Sampling: process by which research select units from a population, population: group being studied, e. g lesbian and bisexual women in nsw, unit: most primary element of a research study. Sample -> findings: findings based on sample, generalisable to population.
