  1. 6.1 Graphical representation of data

    1. 6.1.ADifferent methods of presenting data Pictograms, bar

      use different methods of presenting data Pictograms, bar charts and pie charts, and only two-way tables

    2. 6.1.BTabulating data for statistical diagrams

      use appropriate methods of tabulation to enable the construction of statistical diagrams

    3. 6.1.CStatistical diagrams

      interpret statistical diagrams

  2. 6.2 Statistical measures

    1. Understand averages for data presented in lists or tables.

    2. calculate the mean, median, mode and range for a discrete data set Includes simple problems using these measures

    3. Calculate an estimate of the mean from grouped data.

    4. identify the modal class for grouped data

  3. 6.3 Probability

    1. Use probability language including outcomes, equal likelihood, events and randomness.

    2. understand and use the probability scale P(certainty) = 1 P(impossibility) = 0

    3. understand and use estimates or measures of probability from theoretical models

    4. find probabilities from a Venn diagram

    5. Understand sample spaces and events, and determine event probabilities from a sample space.

    6. List outcomes systematically for single events and for two successive events.

    7. estimate probabilities from previously collected data

    8. calculate the probability of the complement of an event using P(A′) = 1 − P(A)

    9. use the addition rule of probability for mutually exclusive events P(Either A or B occurring) = P(A) + P(B) when A and B are mutually exclusive

    10. understand and use the term ‘expected frequency’ Determine an estimate of the number of times an event with a probability of 0.4 will happen over 300 tries
