Key Terms Flashcards
Validity
Truthfulness and meaning
Reliability
Can it be repeated with the same results?
Quantitative Data
Numerical & statistical data
Qualitative Data
Non-numerical (words and text)
Hypothesis
Scientific prediction on what a researcher thinks will happen
Operationalisation
The process of turning a sociological concept or theory into something measurable
Triangulation
The use of multiple methods to study one research question- to strengthen the argument by counteracting weaknesses of one method. Triangles are the strongest shape.
Pilot Study
A small-scale trial run of a study to test any aspects of the design, with a view to making improvements.
Primary Source
Collected by the researcher from the participants.
The method will be chosen by the researcher so will fit the study well.
Can be time-consuming and expensive. Ethical issues can also arise.
Secondary Source
Sources used that are collected by other people.
Can be cheap and save time as the data already exists.
The methods/type of data may be limited or not suit the study as it wasn’t chosen by the researcher. Ethical issues could still arise (e.g. reading a diary never intended for public use) but are less.
Population
Whole group you want to study
Sampling Frame
A list of those individuals in the population, from which the sample is drawn
Sample
Those who take part
Random Sampling
Every person in the sampling frame has equal chance of being chosen.
More representative than some other methods, but randomness doesn’t ensure this.
Systematic Sampling
A method is devised to enable selection of participants.
Avoids researcher bias is choosing, but generally more biased than random sampling as not all members have an equal chance at selection.
Stratified Sampling
Population divided into groups based on social characteristics. Sample then chosen in the same proportions.
Produces a more representative sample. The grouping cannot reflect all the ways people are different, so it can’t be completely representative.
