Validity = concerns how true the data is. A valid method produces a genuine picture of what
something is like.
Reliability = A reliable method allows the researcher to repeat the method and get the same
Representativeness = data is representative if a cross section of the population is used. If you
have used a cross section then generalisations can be made.…read more
Factors influencing choice of method:
·Time and money Different methods require different amounts of time and money. E.g. A small scale project may be
cheaper but could take a long time to complete.
·Access to subject matter Some sociologists may have limited access to certain things. Also, it might be difficult to
study particular groups.
·Funding Business, charities and governments provide funding for research. This may affect how valid the data is.
·Personal skills and characteristics A sociologists personality may affect their ability to mix with people.
·Sociologists perspective The sociologists perspective may influence their choice of topic.
·Informed consent The researcher should inform the participant about the true nature of the study.
·Confidentiality Researchers should ensure that the identity of the participant is kept a secret.
·Protection from harm The researcher should ensure that there is no risk of physical or mental harm.
·Vulnerable groups Social consideration needs to be given to certain social groups e.g. Young and mentally ill.
Sampling: Social Surveys
To choose a sample we need a sampling frame. An easy way to collect data about people is to ask them questions.
Sampling frame = this is a list of all the members
of the population we are interested in studying. ·Interviews
Types of questions:

·Random sampling from a limited amount of possible answers. These questions are easy to

·Open ended questions Respondent is allowed to give whatever

·Opportunity/convenience sampling Hypothesis = Before a social survey can begin the researcher needs
to formulate a hypothesis. This is a statement that can be tested.

X = random might not give equal proportion question. Research is therefore more valid because we
