Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    How would you justify the inferential test chosen for your own investigation?

    Model answer

    By stating whether you were looking for a difference or a relationship, whether your design was related or unrelated, and what level of measurement your data reached.

  2. 2

    How should the outcome of your own inferential test be stated?

    Model answer

    By comparing the observed value with the critical value for your N or degrees of freedom, then saying whether the null hypothesis is rejected at the 0.05 level.

  3. 3

    How could you assess the reliability of your own observational investigation?

    Model answer

    By having a second observer independently record the same behaviour using the same operationalised categories, then correlating the two sets of records.

  4. 4

    Name two threats to the validity of an investigation carried out in your own school.

    Model answer

    Participants who know the researcher may show demand characteristics, and the artificial setting of a classroom task limits how far the findings apply to everyday behaviour.

  5. 5

    Which ethical code must be followed when carrying out these investigations?

    Model answer

    The British Psychological Society's Code of Ethics and Conduct, which the specification names in its 2009 edition and which has since been revised, must be adhered to throughout, together with the BPS Code of Human Research Ethics.

  6. 6

    State four practical ethical steps to take in a school-based investigation.

    Model answer

    Obtain valid consent, with parental consent for anyone under 16; make clear the right to withdraw at any time; keep all data confidential by using participant numbers; and debrief everyone fully at the end.
