Participants will record a greater increase in heart rate when listening to heavy rock music than when listening to classical/jazz music.
-
Research Design Type
-
Experimental
Advantages
numerous controlled variables and as a single independent variable that is switched by the experimenter.
-
-
As well as well objective quantitative data, subjective qualitative data was collected for additional comparison
Disadvantages
-
Only one trial of experiment occurred, meaning results were open to the heavy influence of random errors
conclusions can not be associated to the 'real world' due to environment in which the experiment was performed
-
Variables
-
Dependent
Heart Rate
Advantages
BPM is a distinct number that can easily be graphed, compared and analyzed
-
-
-
Extraneous
Situational Variable
Situational variables are aspects of the environment that can affect the participant's behavior. They should be controlled so they are the same for all participants.

-
Participant Variable
Participant variables: Participant variables can be defined as the differing individual characteristics that may impact how a participant responds in an experiment

-
Sample Size
-
-
Due to previous knowledge on arousal, students may be biased in performance, to ensure results can match their understanding
-
Ages of students are quite similar, limiting how many other individuals the results can be associated with
Ethical considerations
-
Informed consent: All individuals required to provide signed consent in order to participate in the experiment. Those under 16 were required to have the information sheet signed by a parent/guardian
-
Accurate reporting: This ethical Principle was difficult to control as it was up to the participant to provide honest results. It was assumed that no individual was dishonest, however this cannot be confirmed
Weaknesses
Music listened to at different volumes could have caused varying effects on heart rate for each participant. Volume can make music more or less stimulating. To control this, every participant must listen at the same volume
Having only one trial of the experiment as well as a low sample size meant the results were quite unreliable as there was room for many random errors. The imprecise data is difficult to be used to reflect the wider population.
Different headphone earphones types can vary quality of sound for each participant, meaning they are not all experiencing the exact same experiment. Imprecise results can occur through having the participants experiencing different levels of arousal through their personal quality of music.
