Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is the aim of a piece of research?

    Model answer

    It is a general statement of what the researcher intends to investigate and why, written before any prediction is made.

  2. 2

    How does a hypothesis differ from an aim?

    Model answer

    An aim states the general purpose of the study, whereas a hypothesis is a precise, testable prediction about the variables that the results can either support or fail to support.

  3. 3

    When would you call a prediction an experimental hypothesis rather than an alternative hypothesis?

    Model answer

    It is called experimental when an independent variable has actually been manipulated, and alternative when the study is not an experiment, for example a correlation or an observation.

  4. 4

    What is a directional hypothesis?

    Model answer

    It predicts not only that there will be a difference or relationship but also which way round it will go.

  5. 5

    What is a non-directional hypothesis?

    Model answer

    It predicts that there will be a difference or relationship but does not state its direction.

  6. 6

    When should a researcher choose a directional rather than a non-directional hypothesis?

    Model answer

    A directional hypothesis is used when previous research points clearly one way, and a non-directional one when there is no previous research or the existing findings conflict.
