Quantitative and QualitativeResearch
3 Main Types of Quantitative Research
Correlational, experimental (direttl manipulate the independent variable),, destriptive
Two Main Types of Statistics: Descriptive + Inferential
1: Destriptive: summarizing.
Central tendency:
- mean: most tommon t pe of CT used
- median: works beter with outliers than the mean; allows ou to work with pertentiles
- mode: simplest form of CT; most frequent store (eg: gender),
Variability: how spread out the data is
- Range: lowest store to highest store
- Standard deviatin: how diferent (or how far away most) scores are from the mean (the
lower the beter),
Pertentage intrease: (old-new), / 100 x old
2: Inferential: thetking to see if the differences fonnd in data are dne to chance
Distribution
Mean is the mid-point.

The Scientifc Process
1. Question
2. H pothesis: an edutated guess about the explanation for our observations. In the form of a
statement that tan be tested.
3. Defne our variables
4. Test h pothesis using a sound researth design
5. Anal se data
6. Report fndings
7. More researth and theor building
8. New h pothesis derived from theor (tontinue batk to step 4),
Quantitative Research
Draws on the logical positiiss paradigm (idea that there is an objectie reality),. Asserts that onl
statements verifable through empirital observation are tognitivel meaningful.
Is interested in predittion and tausation.
NB: Goals of quantitative researth:
Describing behaviour
Predictng behaviour
Identif ing causes of behaviour
Explaining behaviour (modelling, desensitisation ett),
Where do stientift ideas tome from? Common sense; Observations; Past researth; Prattital
problems; Theories
Stientift theories
Are grounded in attual data from prior researth
Generate h potheses whith tan be tested. Must be falsifiable.
H potheses
Testable predittions based on theories.
Cannot be proven, only supporsed by research and data.
