information to collect and from where
- work out the size of the sample to be tested and how the
sample will be selected

e.g. by mail-out of questionnaires, experiments, and survey
interviews-either telephone or face-to-face
- work out the most efficient experimental design if
information is to be collected by experiment
- make sure measurement resources are used efficiently
- interpret the data and produce relevant statistics to
describe or infer particular trends and patterns

economic trends

represent data graphically and report findings
