Accurate Calculations

• Check all calculations carefully!
• Computer calculations are allowed and would be a
  GREAT way to check your own answers!

10
Reasons and Explanations

• Before - WHY ?
• are you doing something?
• do you expect something?
• After - WHAT?
• does that show?
• does that mean?

• How is it marked?

12
Mayfield High School

• There is an intended approximate link between
  grade F and mark 3, grade C and mark 5 and grade
  A and mark 7 Edexcel 2002

13
Mayfield High School
There are three strands for marking. 8 marks are
available on each strand, making 24 in total.

• Specify the problem and plan
• Collect, process and represent data
• Interpret and discuss results

14
Specify the Problem and Plan
1 or 2 marks very simple problem, well defined
aims, sensible data, uses only one feature of the
data (e.g. eye colour) 3 or 4 marks Grade
F routine problem, quantitative data, good
description, still only one feature of the data
(e.g. IQ) 5 or 6 marks Grade C substantial
problem, 2 way data (e.g. height weight),
reasons and description, considers outliers 7 or
8 marks Grade A Complex problem, reasons,
predictions, full explanations
15
Collect, process and represent data
1 or 2 marks any sample, tally charts, bar/pie
charts 3 or 4 marks Grade F any sample,
average/range, dual bar charts, scatter graph 5
or 6 marks Grade C random sample, box
whiskers, lines of best fit, equations of lines
of best fit, cumulative frequency diagrams 7 or 8
marks Grade A Stratified sample, histograms,
non-linear scatter diagrams, IQR, percentiles,
standard deviation, correlation measures
(Spearmans rank correlation)
16
Interpret and discuss results
1 or 2 marks simple comments, ordered data 3 or
4 marks Comments on average/range Comment on
correlation 5 or 6 marks Comments on all graphs,
comparisons and contrasts, comments on outliers 7
or 8 marks Full comparisons on all diagrams,
full argument/reasoning for why something may be
true, full discussion of data sampling.

How much time should I spend on it? How long
should it be?

Quote from Edexcel August 2002
a total time allocation of equivalent to two
weeks of class and homework time is sufficient.
Projects need to be succinct and avoid repetition
and unnecessary calculations and diagrams. It is
this misuse of time which often places pressure
on the students
