deconstruction of arousal and relaxation experiment
these are variables that are not the independent variable but could affect the results of the experiment.
drinking coffee before the experiment (participant variable)
taking a maths test before the experiment (participant variable)
participating in physical activity before the experiment (participant variable)
temperature (situational variable)
background noise (situational variable)
As the independent variable being tested is music, background noise has a potential to affect this. Interference with the sound may cause the participants to struggle to hear the track, which would lead to inaccurate results.
they can impact the data in a negative way and lead to inaccurate results
the heart rate may not be the most accurate measure of aroused or relaxed one becomes after listening to the tracks, due to the extraneous variables present which cannot be controlled.
research design type
the sample size was not an accurate represenation of the population being tested
only constitutes for 3% of the entire population
leads to inaccuracy of results
biased, as the sample consists of year 11 students only who undertake pyschology as a subject
they have prior knowledge on
