The Nature Of Quantitative Research (4) Flashcards
What are the stages of the quantitative hypothetico-deductive method
Read the literature
Develop null and experimental hypothesis
Collect and analyse data
Do the results support the null hypothesis
Empiricism
Based on publicly available knowledge
What are the two stages of testing a prediction
Collect appropriate data
Analyse the data
What did Kuhn develop
Paradigm shifts
What did Kuhn define replication as
Constant evaluation of the theory
What are the stages of planning research
Your hypothesis
Design
Data collection
Analysis
What should you consider with quantitative research
Design
Variables
Samples
Analysis
What are the 4 types of survey
Questionnaires
Interviews
Focus groups
Internet
What should you avoid in surveys
Using examples
High reading level
Jargon
Double barrelling
What should you beware of in a survey
Acquisition bias
Order effects
What three ways can you validate results
Cronus has alpha
Test retest
Statistical significance if validity process
What does your sample need to be in order to have generalisable results
Representative
Unbiased
Quota sampling
Like stratified sampling but more general
Self-selecting sample
Ppts volunteer
Opportunity/convenience sample
Selection is based on availability-non random
Purposive sampling
Selection is determined by the researcher based on the ppt satisfying the criteria
Snowball sampling
Ppt knows others that fit criteria
Critical cases
Rare occurrences provide insight to conditions you cannot create
Focus groups
Individuals who fit criteria meet to discuss particular issues
What four things should you consider when calculating sample size
Level of desired confidence interval
How small we want sampling error to be
How much variance there is in behaviour being measured
Overall size of total population
What do we use to tell us whether our data supports our theory
Statistics
What is the probability value that we use
0.05
