Given a problem that can be addressed by statistical methods, suggest possible answers.

Design a data collection sheet or questionnaire to use in a simple survey;

construct frequency tables for discrete data.

Calculate statistics for small sets of discrete data:

find the mode, median and range;

calculate the mean, including from a simple frequency table, using a calculator for a larger number of items.

Construct, on paper and using ICT, graphs and diagrams to represent data, including:

bar-line graphs;

use ICT to generate pie charts.

Write a short report of a statistical enquiry and illustrate with appropriate diagrams, graphs and charts, using ICT as appropriate; justify choice of what is presented.

Core:

Discuss a problem that can be addressed by statistical methods and identify related questions to explore.

Decide which data to collect to answer a question, and the degree of accuracy needed; identify possible sources.

Plan how to collect the data, including sample size;

design and use two-way tables for discrete data.

Collect data using a suitable method, such as observation, controlled experiment using ICT, or questionnaire.

Calculate statistics, including with a calculator; recognise when it is appropriate to use the range, mean, median and mode; construct and use stem-and-leaf diagrams.

Construct, on paper and using ICT:

pie charts for categorical data;

bar charts and frequency diagrams for discrete data;

simple scatter graphs;

identify which are most useful in the context of the problem.

Interpret tables, graphs and diagrams for discrete data and draw inferences that relate to the problem being discussed; relate summarised data to the questions being explored.

Communicate orally and on paper the results of a statistical enquiry and the methods used, using ICT as appropriate; justify the choice of what is presented.

Solve more complex problems by breaking them into smaller steps or tasks, choosing and using resources, including ICT.

Extension:

Discuss how data relate to a problem; identify possible sources, including primary and secondary sources.

Gather data from specified secondary sources, including printed tables and lists from ICT-based sources.

Interpret graphs and diagrams and draw inferences to support or cast doubt on initial conjectures; have a basic understanding of correlation.
