aims and hypotheses

• aims

  -          aims need to be developed before designing and carrying out research.
• aims

  -          a name is a general statement which outlines what it is that is being investigated/ the purpose of the investigation.

  -          a name is developed from previous theories and research it is not just random.
• hypotheses

  -          a hypothesis is formulated once it aims has been decided.
• hypotheses

  -          a hypothesis is a specific prediction about the outcome of an investigation that will be specifically tested in the study therefore it needs to be written out clearly and be fully operationalized.
• hypotheses

  -          A researcher either accepts or rejects A hypothesis based on the data that is collected.
• hypotheses

  -          A null hypothesis states that there is no change or difference in the measurement of the dependent variable as a result of the manipulation of the independent variable- there is no correlation between the two.
• hypotheses

  -          Alternative hypothesis- these hypothesis states that there is a change slash difference in the measurement of the dependent variable as a result of the manipulation of the independent variable.
• hypotheses

  -          Directional hypothesis- is a type of hypothesis that predicts the direction of results for example one condition of the independent variable has a more, less, greater, faster, slower effect on the dependent variable.
• hypotheses

  -          non directional hypothesis is a type of hypothesis which is less specific than a directional hypothesis and does not predict the direction of the results- it states that there will be a difference but doesn't describe the condition.
• hypotheses

  -          a non-directional hypothesis is used when they are investigating an area with little existing research.

  -          an example of a non-directional hypothesis would be- there will be a significant difference between the number of words correctly recalled from a list of 15 by adults aged 1830 in comparison to children aged 9 to 12
• hypotheses

  -          where is the directional hypothesis would say there will be significantly more words correctly record by the adults than from the children
