Types of data
What is primary data? Data you've collected yourself
What are the advantages of primary data? You know it's reliable, It hasn't been changed by anyone
What are the disadvantages of primary data? Time consuming, Could be biased
What is secondary data? Data you did not collect yourself but still use
What are the advantages of secondary data? You can use data that you may not have been able to collect yourself e.g. historical data or national survey
What are the disadvantages of secondary data? May be false, Don't know where it's from, Is it valid?
What is quantitative data? Data using numbers which can be changed to statistics
What is qualitative data? Deals with types of things (categories etc) rather than number data
Factors affecting choice of method
Practical issues
Time and money - It can take alot of both to produce a good questionnaire, collect data and organise it
Requirements of funding bodies - To fund your research, they may also influence your questions and/or your answers
Personal skills and charateristics - How you communicate with people, are you biased or judgmental ?
Subject matter - What are you researching and why
Research opportunity - When and where are you conducting your research
Factors affecting choice cont.
Ethical issues
Informed consent - Participants need to know full aims of the study and purpose of the research
Confidentiality and privacy - How are you keeping the data private
Vulnerable groups - How will you protect them
Effect of research on participants - E.g. psychological affects - how will you deal with it
Covert research - undercover research, people don't know that they are part of your research, this can cause legal problems
Factors affecting choice cont 2.
Theoretical issues
Validity - Interpretivists believe that observation is one of the best ways to guarantee validity as it shows people an authentic view of the world. However the observer may affect behaviour of participants, this will affect the validity of the study
Reliability - Methods such as questionnaires, structure interviews, experiments, comparative and observational studies are acceptable because they offer higher levels of reliability than qualitative methods
Representativeness - Not everyone may be represented. How will you deal with that?
Methodological persective
Positivist - positivism means 'scientific' and their methodologies argue that it is possible and desirable to study social behaviour in ways similar to those used by natural scientists to study behaviour in the natural world
Interpretivist - For interpretivists the social world consists of and is consttucted through meanings e.g. everytime you go to school, this behaviour helps recreate the structure of education
Why choose to study a certain topic
Theoretical perspective - To get evidence for the theory
Information is out there already so easy to obtain
Back up other evidence for the theory
Society's values - To track how society has changed
Learn how to stop crime using values
How does society think
Problems with experiments
Practical problems -
Researchers take a long time to get used to where their observation/experiment is taking place and understand how the place operates.
Time may be limited e.g. restricted working hours etc.
Participants may be decieved, how could this be dealt with.
Ethical problems -
Covert observations are inappropriate in a number of settings.
Identity of people involved must be protected.
If the observer sees someone breaking the law they have to make the decision whether to report them or not.
Experiment types
Laboratory experiments - Usually involve two groups, experimental group and control group (extraneous variables are controlled), Set in a artifical environment.
Advantage - They are highly reliable
Disadvantage - Not a natural setting
Positivists like lab experiments because they are scientific, easy to analyse and compare data, based on facts rather than opinions.
Field experiments - In a natural environment but have controlled variables
Advantage - Broader focus of research, it looks at many variables.
Disadvantage - Can be resticted by extraneous variables connected to the environment.
Surveys
There are two types of survey: Written questionnaires and interviews
There are two types of questions: Closed ended questions and open ended questions
Before you conduct a survey you must do the follwing procedure :
1. Choose a topic to research
2. Formulate an aim or hypothesis
3. Do a pilot study
4. Select a sample
Sample types
Random sampling - Everyone has an equal chance of being selected
Quasi -random sampling - choose participants using a sampling frame
Stratified random sampling - Divide the target population into sub-catergories selecting members from each that occur in the population
Quota sampling - Same as stratified
Voulnteer sampling - Ask people to be part of your research
Opportunity sampling - Ask the first people you see
Snowball sampling - A few participants are selected they then put the researcher in contact with other possible participants
Questionnaires
Advantages - Quick and easy
Reliable
lots of data gathered
Disadvantage - People may lie
Questions may be biased
Low response rate
Inflexibility
Forgetting and 'right answerism'
Inerviews
Types of interviews
Structured - A formal interview with a set of questions to ask the participant.
Semi - structured - A mixture of questions that may be asked
Unstructured - Open questions used so participants give full answers, there may not be a set of questions to answer.
Group interviews - self explanatory
Focus groups - A group interview with only one topic of discussion
Representativeness - Not everyone's views may be representent no matter which type of interview is used.
Reliablity - Low level reliability, they same answers may not always be given.
Observation
Non-participant observation - The observer watches from afar, people are not involved closely.
Participant observation - Observer gets involved in what they are observing
Overt observation - Participants know what you are observing and why
Covert observation - Undercover observation, people do not know why you there, yo may pretent to be someone else.
Offical statistics
Types of offical stats : Census
Inland revenue
Government collect them to show up patterns and trends in society that may need addressing e.g. rising crime rates in a certain area.
They collect the statistics via questionnaires, surveys and exam results etc.
They are qualitative data
Advantages include: representativness, reliability, easy to produce, easy to compare.
