Data analysis

Data analysis.

• Candidates should be able to:.
• present and interpret data in tables.
• understand the meaning of 'measure of central tendency'.
• name, recognise and know how to find measures of central tendency:.

This matters because data analysis determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply data analysis to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Data analysis is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
