Psychology - Correlation Study
From the Integrating Mathematical Problem Solving project by Mathematics in Education and Industry (MEI), this activity for post-16 students shows that correlation can be used to measure the strength of a linear relationship.
Statistical Inference looks for evidence of what is happening in the population by looking at a sample. Different samples from the same population can give different results.
Mathematical There is an experiment which is best done in a lesson before the results are analysed.
The teachers' notes are written to be suitable for teachers of either mathematics or psychology. This unit assumes that students have come across scatter diagrams and basic ideas of correlation, perhaps at GCSE, but they do not need to be able to calculate a correlation coefficient before starting the unit.
