Questions and Answers

Which of the following is a key feature of experimental research?

  • The researcher manipulates or varies the outcome variable
  • The researcher keeps everything constant except for the outcome variable
  • The researcher controls all aspects of the study (correct)
  • The researcher allows the predictor variables to vary naturally

    • What is the purpose of randomisation in experimental research?

  • To manipulate the predictor variables
  • To vary the outcome variable naturally
  • To eliminate the possibility of any causal effects on the outcomes
  • To ensure that there are no systematic differences between groups (correct)

    • Why is it almost impossible to keep everything constant in an experiment?

  • Randomisation is not effective
  • The predictor variables cannot be manipulated
  • The researcher has limited control over the study
  • There are too many potential factors that can influence the outcome (correct)

    Study Notes

    Experimental Research

    • A key feature of experimental research is the manipulation of one or more independent variables to observe their effect on the dependent variable.
    • The purpose of randomization in experimental research is to ensure that the groups being compared are equivalent in all relevant aspects, except for the independent variable being manipulated.

    Research Design Limitations

    • It is almost impossible to keep everything constant in an experiment because there are many extraneous variables that can affect the outcome, and it is difficult to control for all of them.

    Types of Research

    • Case studies aim to provide a very detailed description of one or a few instances, often involving in-depth analysis of a particular case or phenomenon.

    Quasi-Experimental Research

    • The main difference between quasi-experimental research and case studies is that quasi-experimental research involves some manipulation of an independent variable, but without randomization, whereas case studies do not involve manipulation of an independent variable.

    Non-Experimental Research

    • Non-experimental research designs may fail to provide valid results because they do not involve manipulation of an independent variable, making it difficult to establish causality.

    Case Studies

    • The advantage of case studies compared to experimental and quasi-experimental designs is that they provide rich, in-depth insights into a particular case or phenomenon, which can be valuable for understanding complex issues or phenomena.
