The Effectiveness of VRET (DP IB Psychology): Revision Note

Here is an example of a Paper 3 source and a 3-mark SAQ using technology (HL extension) in the Health & Wellbeing context:

Source 1:

Q1. Explain one limitation linked to the interpretation of the data in this source.

[3 marks]

Model answer:

Self-efficacy was measured on a scale of 0-10 (see the y-axis). This is a limitation, as self-efficacy is a subjective variable (it means different things to different people) so it may defy quantitative measurement.

or

The x-axis does not indicate how much time has passed between each measurement, which means that it is not possible to form a meaningful conclusion about the long-term effects of VRET compared to VRET + DB.

Guidance

• Use only the information provided by the graph/chart: do not 'invent' data or make assumptions as to what may be behind the data, e.g., what the VRET consisted of or your own opinions on VRET generally

• Do not write too much – there are only 3 marks available for this question and you need time to complete the higher-value questions on this paper

• The question is asking for one limitation so don't provide two or more, as you will not be rewarded for this

• The question is asking for what limits interpretation of the data so don't waste time/marks by stating any advantages/strengths
