    Cards (21)

    • What is an aim?
      A goal or objective of research
    • what do aims take the form of?
      general statements covering the topic/theory/concept that will be investigated
    • what do aims identify?
      purpose of research
    • what do aims outline?
      what is being studied and what the study is tying to achieve
    • what is a hypotheses?
      a testable statement written as a prediction of what the researcher expects to find as a result of their experiment
    • what must a hypotheses be?
      precise and unambiguous
    • How is the aim of the study expressed?
      in general terms
    • what do aims outline?
      the focus of the study
    • what are the 2 types of hypotheses?
      Null and alternative
    • what should an alternative hypothesis include?
      an IV and DV
      • both should be operationalised
    • what is an alternative hypothesis?
      hypothesis suggesting there is a difference or effect between variables
    • how can the IV be operationalised?
      by providing different conditions which are specific
    • how can the DV be operationalised?
      • by having a unit of measurement eg. seconds, score on a test
    • what are the 2 types of alternative hypotheses?
      • directional (one-tailed)
      • non-directional (two-tailed)
    • what do directional hypotheses predict?
      The direction of the difference between conditions
    • what do directional hypotheses suggest?
      one condition will out-perform the other
      • either positive or negative
    • what do non-directional hypothesis not predict?
      direction of the difference in conditions
    • what kind of hypothesis do all research start as?
      Null
    • What do null hypothesis suggest?
      No effect of IV on the DV
    • why do all research start as null hypothesis?
      until experiment has been conducted & results are analysed it is impossible to state anything els
    • what words will hypothesis for a correlation use?
      relationship
