Y10 Foundation: Topic 15 and 16: Informations from small data sets, Probability 1

Objectives:

Find the mode, the median, the mean, and the range for (small) sets of data

Use a stem and leaf diagram to sort data

Know the advantages/disadvantages of using the different measure of average

Compare distributions using a measure of average and the range

Use the language of probability to describe the likelihood of an event

Represent and compare probabilities on a number scale

List outcomes for single mutually exclusive events and write down their probability

Prior Knowledge:

Some experience of the measures of average

Ability to order numbers

Some idea of chance and the likelihood of an event happening; and recognition that some events are more likely than others

Experience of using the language of likelihood

Key Vocabulary:

Copy and paste here.

Differentiation & Extension:

Collect data from class — children per family etc

Find measures of average for data collected in a frequency distribution

Use stem and leaf diagrams with unusual stems, eg 234.1, 234.6, 235.1, ...

Discuss occasions when one average is more appropriate, and the limitations of each average

Compare distributions and making inferences, using the shapes of distributions and measures of average and spread, eg ‘boys are taller on average but there is a much greater spread in heights’

Write down probabilities of events that may or may not happen

Play simple probability games, predicting outcomes, eg horse race for sum of two dice

Using & Applying ideas:

NOTES

Students tend to select modal class but identify it by the frequency rather than the class description

Explain that the median of grouped data is not necessarily from the middle class interval

Where possible introduce practical work to support the theoretical work

Only fractions, decimals or percentages should be used for probability
