Social Surveys
Types of samples
Quota samples
-
-
It is a type of stratified sampling in which the selection of people within each stratum is not random
-
Snowball sampling
Sometimes researchers have great difficulty obtaining people for their samples due to lack of sampling frame or people not wanting to be identified
-
-
it is unlikely to provide a representative sample since it is not random and relies on personal contacts and recommendations
-
Volunteer samples
Volunteer samples are made up of people who volunteer to take part in the research (from seeing posters or advertisements etc..)
Volunteer samples have the advantage that those who take part are likely to be interested in the topic and keen to participate
-
Those who volunteer may have a particular reason for doing so
-
Definition
A social survey involves the systematic collection of the same type of data from a fairly large number of people
-
they can be given to participants to complete themselves
can be given by an interviewer- read out to the participant with the answer recorded - structured interview
Samples
-
Samples are necessary because researchers rarely have the time and money to study everybody in the particular population to be investigated
-
With a representative sample, generalisations are more likely to be true - more likely to be applicable to the population as a whole
Sampling unit and frame
Sampling unit is a member of the population to be studied eg. females who own their own business, dentists etc…
Once the research population has been defined, the sample is selected from a sampling frame- a list of members of the population to be studied
In some cases, an appropriate sampling frame is readily available but there are some drawbacks such as data being out of date and certain groups being underrepresented eg. poor people are less likely to be on phone directories

Web Surveys
Advantages
Respondents can clearly see that they will remain anonymous. This is important for many people regarding sensitive/illegal topics
-
-
-
Disadvantages
It is not possible to tell whether those who respond are representative of the population being studied - it is not possible to generalise
Those who respond may have particular reasons for participating in the survey- not known to the researcher
There may be important differences between those who choose to respond and those who chose not to respond
