The third in a trilogy of related psychology research methods films (the first and second look at Experimental and Non-Experimental Research Methods respectively) examines how statistical data are collected, compared and explained through an examination of three key issues in this process:
1. Sampling introduces and illustrates a range of important concepts (target population, sample, representativeness, generalisability), explores different types of probability and non-probability sampling (simple random, stratified, opportunity…) and evaluates their respective strengths and weaknesses in the context of developing statistical data.
2. Correlations outlines and explains the concepts of positive and negative correlations, introduces the idea of correlation co-efficient and explores the strengths and limitations of correlations in the context of statistical data.
3. Experimental Design begins by looking at the idea of causation in the context of experimental methods and research design. The strengths and limitations of three types of design (Repeated Measures, Independent Measures and Matched Pairs) are illustrated using a range of contemporary and classic studies.

When looking at statistical relationships, a useful student exercise to demonstrate how social factors underpin the production of crime data is to examine their underlying causes.
This piece of research, from The Adolescent and Children’s Trust (Tact) and University of East Anglia, can be used to effectively illustrate this idea. It also has further interesting applications when looking at areas like the relationship between age and crime.
The 2015 A-level Psychology Specifications place a new emphasis on students’ ability to both understand and, more-importantly, apply a range of statistical tests to psychological problems.

Each film takes students through the basic steps needed to calculate and apply the tests to various research methods. The films are available in a range of formats:
48-hour rental: All 6 films available for on-line viewing.
DVD: all 6 films: £17.50
The Office for National Statistics (ONS) is always a go-to source for all types of statistical data on a variety of topics and this one is no exception.
With links to both gender and social inequality “Welcome to unequal England” uses ONS data to show how inequalities impact on some of the most important life chances of all – the ability to live a long, healthy, life.
