These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Correlations between variables can be positive or negative and can be of differing strengths.
  2. Interpolation and extrapolation help geographers estimate unknown values in a set of data.
  3. Geographers often consider the ethical aspects of their fieldwork.

Keywords

  • Interpolation - finding the value of data in a set by examining the data that falls either side of it in sequence

  • Extrapolation - finding the value of data in a set by extending the correlation beyond the known data

  • Ethical considerations - areas of the fieldwork investigation where geographers consider the impact their study may have on people and the environment

Common misconception

The angle of the line of best fit tells geographers how strong the correlation is between two variables.

The strength of the correlation is decided by how close the plots are to the line of best fit.

When students consider environmental ethics in their enquiry they can break these down into smaller areas such as the impacts on air, land and water, or the impacts in the short term as well as the long term.
