According to positivists, why should sociology model its research methods on those of the natural sciences?
In their view, this will produce objective, true, scientific knowledge of society.
Give an example of a pattern of social reality.
There are clear patterns of educational achievement and underachievement.
According to positivists, why do social patterns exist?
They exist because society exerts an influence over its members, systematically shaping their behaviour in various ways.
How can cause and effect be discovered?
Positivists believe through careful observation and measurement , they can discover laws of cause and effect that explain social patterns.
Give an example to show how quantitative data can be used to show patterns of behaviour in society.
Quantitative data on exam results may show class differences in achievement. By correlating this with other quantitative data on class differences in income, we may be able to show that low income is a cause of underachievement.
In what sense is a laboratory experiment a controlled experiment?
The laboratory is an artificial environment on which the scientist can control different variables in order to discover what effect they have.
Briefly explain what happens to the experimental group in an experiment.
The experimental group are exposed to a variable (independent variable) that the researcher believes may have a particular effect.
Briefly explain what happens to the control group in an experiment.
The control group aren’t exposed to the independent variable - their conditions are kept constant.
Briefly explain how a laboratory experiment can show cause-and-effect relationships.
The condition of both groups is recorded before and after the experiment. If a change is discovered in the experimental group but not the control group, they may conclude that this was caused by the treatment the two groups received.
Briefly explain the following practical issues associated with laboratory experiments:
Open systems:
Individuals are complex:
Briefly explain the following practical issues associated with laboratory experiments:
Studying the past:
Small samples:
Briefly explain the following practical issues associated with laboratory experiments:
The Hawthorne effect:
The expectancy effect:
Briefly explain the following ethical issues associated with laboratory experiments:
Informed consent:
Harm to subject:
According to positivists, what is the theoretical strength of laboratory experiments?
Their reliability. However, in other respects they suffer from important limitations even from a positivist perspective.
Briefly outline three reasons why positivists regard laboratory experiments as highly reliable.
According to positivists, why is representativeness important?
Because they aim to make generalisations about how the wider social structure shapes individuals’ behaviour.
What is meant by external validity?
We cannot be confident the findings are true for the wide population.
Briefly outline two reasons why laboratory experiments may lack external validity.
What is meant by internal validity and why might laboratory experiments lack it?
Their findings may not be true for the subjects of the experiment itself, let alone the wider world.
According to interpretivists, why are laboratory experiments inappropriate for studying human beings.
Briefly outline two ways in which a field experiment differs from a laboratory experiment.
- Those involved don’t know they’re subjects of an experiment, thereby avoiding the Hawthorne effect.
What variable did Rosenthal and Jacobson manipulate in their field experiment and how did they do it?
They manipulated teachers’ expectations about pupils by giving them misleading information about the pupils abilities in order to discover what effects this had on the children’s achievement.
Briefly explain the following types of field experiment:
Actors tests:
Correspondence tests:
- Wood et al (2010) sent closely matched job applications for almost 1000 vacancies, apparently from three different applicants of different ethnicity.
What is the value of field experiments?
They’re more natural and valid for real life, and they avoid the artificiality of lab experiments.
