Time when choosing a research method
Some methods may take more time because of for example more detailed data being obtained, research methods that take more time may lead to a smaller research sample size.
Money when choosing research method
The money available affects the number of researchers, respondents and amounts of research time. Equipment, travel, and people’s time are not cheap
Access when choosing research method
Some groups of respondents and location are easier to access than others. For example, to enter a school to do research, permission is required.
Ethical issues
Informed consent
Researchers should have the informed consent of their research subjects, because of the effects that the research may have on them.
CONFIDENTIALITY
Research subjects have a right to anonymity, so they should not be identifiable when the research is published.
PSYCHOLOGICAL HARM
Some research groups are more vulnerable to psychological harm than others (eg. children)
Theoretical issues
RELIABILITY
For a research method to be reliable, it must be able to be repeated and obtain similar results. Positivists favour reliable research and therefore use methods such as questionnaires and structured interviews, that can be repeated by any researcher due to the structured conditions.
REPRESENTATIVENESS
For a research method to be representative, the sample group must have similar characteristics to those of the wider population. Positivists value representativeness because they wish to discover general patterns and make cause and effect statements about social behaviour
VALIDITY
Validity refers to how true the data is. Interpretivists emphasise the need to use research methods rich in validity, such as unstructured interviews and participant observations because they reveal the real meanings in which people hold.
EXPERIMENTS
An experiment is characterised by its high degree of control that the researcher has over the situation. In an experiment, the researcher identifies and controls all variables that might affect the outcome. By manipulating the variables and observing what happens, the researcher can discover cause and effect relationships. There are two main types of experiments: laboratory experiments and field experiments.
LABORATORY EXPERIMENTS
Favoured by positivists, lab experiments test hypothesise in a controlled environment where the researcher changes the independent variable and measures the effect on the dependent variable.
ADVANTAGES
Highly reliable- the original experiment can specify precisely what steps were followed in the original experiments
Can easily identify cause and effect relationships
DISADVANTAGES
Artificiality - lab experiments are carried out in a highly artificial environment and may not reveal how people act in the real world, any behaviour in these conditions may be artificial.
The Hawthorne effect - a lab is not a formal or natural environment - If people know they are being studied, they may act differently.
Ethical issues - the researcher needs informed consent of the participants - this may be difficult to obtain
Unrepresentative: the small-scale nature of lab experiments reduces their representativeness
It would be impossible to identify and/or control all the variables that might exert an influence on certain social issues (Eg. a child’s education)
Field EXPERIMENTS
Field experiments take place in the real social world, whereby the sociologist either creates a situation or adapts a real-life situation to their research purpose. Those involved are usually unaware of the research taking place.
ADVANTAGES
Less artificiality - field experiments are set in real-world situations.
Validity - people are unaware of the experimental situation (no Hawthorne effect) and are in their usual social environment, they will act normally
DISADVANTAGES
Ethical issues - involves carrying out an experiment on people without their informed consent
Less control over variables
Limited application - field experiments can only be applied to a limited number of social situations
Questionnaires
Favoured by positivists, written or self-completed questionnaires are a form of social survey and can be distributed in a range of ways - notably, via post, email or handed out in person. Questionnaires are typically a list of pre-set questions that are closed-end questions with pre-coded answers.
ADVANTAGES
Practical - questionnaires are cheap and quick
Quantifiable data
Representative - reach a geographically widespread research sample
Reliable - the questionnaire can be easily repeated due to how the questions are pre-set
Limited ethical issues - the respondent is under no obligation to answer the question
DISADVANTAGES
Response rate - postal questionnaires, in particular, obtain a very low response rate, which may hinder the representativity.
Low validity - People may be more willing to lie.
Unrepresentative - You are likely to get a certain group of people, for example, the unemployed or elderly that answer the questionnaire as many other people might be too busy, and so you won’t get a particularly representative sample.
The interviewer isn’t there to ask follow-up questions and explain questions the participants if they don’t understand
Interviews
In sociological research, there are different types of interviews: structured interviews and unstructured interviews (including group interviews). Sociologists sometimes use semi-structured interviews to combine the elements of both. Structured interviews are favoured by positivists because they are rich in reliability and representativity, whereas unstructured interviews are favoured by interpretivists because they are rich in validity.
