Theory And Methods (1+3) Flashcards
Describe the Research Process
1) make observation
2) develop hypothesis
3) choose method
4) develop procedure
5) collect data
6) analyse data
7) draw conclusion
Define primary data
Present time data, researched by the individual
What are the benefits of primary data?
Accurate+reliable
What are the negatives of primary data?
Expensive and time consuming
Define secondary data
Data that already exists, and is completed by somebody else
What are the benefits of secondary data?
Cheaper, less time consuming
What are the negatives of secondary data?
Inaccurate, no control how data is produced
Define quantitative data
Numerical data
What are the advantages of quantitative data?
Useful for statistical analysis
Positivists prefer it as it is more objective and scientific
Reveals trends and correlations
What are the negatives of quantitative data?
Interpretivists - doesn’t give real picture of society
Define qualitative data
Non numerical, exists as text
Explores motivations and emotions
What are the benefits of qualitative data?
Interpretivists - more valid
What are the negatives of qualitative data?
Avoided by positivists- difficult to analyse systematically
Define target population
Everyone the researcher would like to generalise findings to
Define sample
Subset of target population being studied
Can be random or intentional
Define informed consent
Aims and procedures are fully explained to participant and they agree to be a part of the research
What are the practical issues that can affect choice of methods and sources?
Time
Money
Access
Researchers characteristics
How can time effect the choice of methods and sources?
More in-depth the method, longer it takes
Primary research takes longer than secondary sources
How can money effect the choice of methods and sources
More in-depth the method, more expensive
Primary data costs more than secondary data
Gov more likely to fund quantitative over qualitative
How can access effect choice of methods and sources
Some topics more difficult to access than others
How can researchers characteristics affect choice of sources and methods
Family and work may prevent long term research
Some topics better suited to specific types of researchers
What are the different types of sampling?
Opportunity Snowball Volunteer Random Stratified Systematic Quota
Define opportunity sampling
Researchers select participants based on availability (eg. asking pedestrians on the street)
What are the benefits of opportunity sampling?
Quick
Easy
Practical
What are the negatives of opportunity sampling?
Not representative
Can’t generalise
Define snowball sampling
Finding participants by getting current participants to pass on the research
What are the benefits of snowball sampling
Simple way to access large numbers of people
What are the negatives of snowball sampling
Not representative of any identified target
Define volunteer sampling
Where participants choose to joint the research
What are the benefits of volunteer sampling?
Simple and cheap
What are the negatives of volunteer sampling
Won’t generate representative sample
Define random sampling
Participants selected at random from a list or generated from a computer
What are the benefits of random sampling
Representative sample
What are the negatives of random sampling?
Time consuming
Subject to bias
Define stratified sampling
Sampling frame divided into various social groups and then randomly selected
What are the benefits of stratified sampling
More precision in sample
Smaller
Cheaper
What are the negatives of stratified sampling
More administrative effort
More complex
Define systematic sampling
Researcher selects every nth person
Nth person selected by target population divided by desired sample size
What are the benefits of systematic sampling
Representative
What are the negatives of systematic sampling
Some social groups could be over/under represented
Define quota sampling
Participants selected based on fixed standards
What are the benefits of quota sampling
Quick and easy
What are the negatives of quota sampling?
Can’t make statistical inferences from sample to population.
