Data collected about class
family size (no. of brothers &
sisters). Data collected and
organised into a frequency
table. Averages discussed
and mean, median and
mode calculated. Method for
identifying quartiles shown &
5 figure summary found.
Pupils shown how to
construct a box plot for the
above data sample. On the
same diagram, pupils draw a
box plot for their previous
homework’s dataset. Box
plots compared and
discussed with class.
Interpretations noted as
comments.
NAB1 test marks for class
collected and converted to
percentage. Idea of grouped
data discussed then
incorporated into frequency
table. Mid-point used to find
f X x. Mean estimated from
the table. 5 figure summary
found (using ordered data
set) and box plot drawn.
Range found. Semiinterquartile range found.
Idea of spread discussed
further.
Data collected about class family
size (no. of brothers & sisters) from
a different class.
Pupils have to repeat classroom
activity for the new data set and
find the 5 figure summary.
Data collected about shoe sizes of
class.
Pupils to construct frequency table,
find averages, find the 5 figure
summary and draw a box plot to
illustrate the information.

Special Notes
Homework
Statistical information from a
different Int2 (NAB1) class
results gathered. Data
ordered and 5 figure
summary found. Mean also
calculated using statistical
mode on the OHP scientific
calculator. Box plot drawn
and compared with the the
previous box plot for our
own set of NAB1 results.
Semi-interquartile range
found. Comparisons made
and discussed. Conclusions
drawn.
Obtain a small data set with
manageable numbers.
Construct a table to find the
standard deviation (s).
Explain why it is so named.
Demonstrate how the one
pass formula can be used as
a much quicker method of
finding (s).
Question 1 is a good
example to do with the class
on the board. In addition you
can also find the 5 figure
summary and semiinterquartile range. Compare
the Standard deviation to the
S-I range.
Introduce probability.
Explain the scale 0-1 with
suitable examples. Explain
notation and the formula
P(Event)=Favourable
outcomes/all possible
outcomes.
Show some examples

Homework
Give examples of multiple
outcomes i.e. rolling two
dice or a spinner and a coin
etc. Show all possible
outcomes in a table and ask
class to calculate some
probabilities.
Introduce Relative
Frequency using qu1 in Ex9.
Collect shoe sizes and hand
lengths (cm) from the class.
Draw a scatter diagram
which should show a
“sausage shape” scatter of
points. Draw best fitting
straight line and determine
it’s equation. Use the
equation as a predictor.
Pupils do Ex 7 p175.
Further examples from the
text book discussed and
illustrated on the board.
Mean of both data sets used
to help draw best fitting
straight line.
Question 6 can be worked
through with the class as an

Revision of topic
Graphs, Charts and Tables
As many real life data sets should be used as possible through class surveys or using information sourced elsewhere (newspapers, internet, class marks etc.). Although
not strictly “problem solving”, there should be strong emphases given to forming conclusions after analysis and in the understanding of answers. Using statistics as a
method for comparing data sets is also vitally important and essential for tasks to be context set.
