Research methods and sampling techniques

3. Type of sampling where it is easier to obtain participants, but often leads to strong self-selection bias.
5. Sampling technique useful for accessing hard-to-reach or hidden populations.
6. Method that involves high level of control, allowing researchers to establish cause-and-effect.
8. Method where behaviours are recorded in real time, increasing ecological validity.
10. Sampling that is quick and convenient, but often unrepresentative of the wider population.
12. Method useful for identifying relationships when experiments are not possible.
14. Type of experiment that uses random assignment, increasing internal validity and control over confounding variables.
15. Type of interview that produces easily comparable data because all participants receive the same questions.

1. Type of experiment that lacks random assignment, reducing internal validity and control over variables.
2. Method that provides highly detailed, in-depth information about a unique individual or situation (no space).
4. Technique that reduces sampling bias by giving everyone an equal chance of selection.
7. Sampling technique which ensures participants have specific characteristics relevant to the study.
9. Type of sampling that produces a more representative sample by including all key subgroups.
11. Method that allows researchers to gather rich, qualitative data directly from participants.
12. Type of observation that reduces demand characteristics because participants do not know they are being observed.
13. Method that encourages participants to build on each other’s ideas through group interaction (no space).
