Marking Criteria – Part A

Read the marking criteria carefully and consider them when preparing your Part A Submission.

See the marking and feedback sheet, page 3 Part A coversheets, for allocation of marks.

Note: you will use these criteria to self-mark Part A of the project – however, your mark for Part A will be based on successful submission of an acceptable attempt.

 

Statistical Calculation

  • To obtain full marks your graph must be correct, including correct labels on both axes and a title. Marks will be deducted if:
  • Graph incorrect (eg, gaps between classes of non-zero frequency in a histogram for continuous data).
  • Excel, or similar, is not used.
  • Axes incorrectly or not labelled.
  • No title.
  • Inappropriate classes are used.
  • Scale on axes distorts graphs.
  • To obtain full marks for descriptive statistics copy the output table of the Descriptive Statistics command in Data Analysis or Descriptive Summary command in PhStat. You may delete unnecessary statistics in this table; you may also include other statistics, for example quartiles.
  • Marks will be deducted if this table is incorrect, so check:
  • Your sample size.
  • Whether you are calculating sample statistics or population parameters.


 

Written Answer – Letter/Email  

  • 300 to 500 words and one to two pages - marks will be deducted if this is greatly exceeded.
  • To obtain full marks must:
  • Be well structured.
  • Clearly communicate the results of the Excel output in language appropriate for your audience.
  • Include appropriate graph and summary statistics.
  • Provide information on average price of three and four year old used cars, how prices vary and any pattern to prices.
  • Provide an estimated price range for a three or four year old used car.

 

  • Marks will be deducted if:
  • There is little or no comment on, or interpretation of, the Excel output.
  • Unnecessary statistical jargon and equations appear.
  • It is confusing or not readable.
  • It is handwritten.
  • For each major spelling and/or grammatical error half a mark will be deducted, up to a maximum of two marks.
  • Also up to two marks may be deducted for poor structure and/or presentation.
