  • Aims and Hypotheses
    • non-directional
      • non-directional would predict a difference but not which will do better or worse
    • Alternative hypothesis
      • If data forces you to reject your null hypothesis then accept your alternative hypothesis
      • if null hypothesis is two variables aren't linked then alternative is they are
    • Null hypothesis
      • Is what you're going to assume is true during the study. Data collected will either back this assumption up or it won't.
        • if data doesn't support null hypothesis, you reject it and go with the alternative.
    • Although the aim states the purpose of a study it isn't usually precise enough to test what is needed- the hypotheses states a prediction
    • directional hypothesis
      • suggest which way the results will go - one thing will do better/worse than the other
