This activity demonstrates how a simple correlation analysis can be carried out. Correlations tell us about the relationship between pairs of variables. For example:
shoe size and height;
age and language learning performance.
The example used in this activity relates to the influence of personality on time perception. The expectation is that there is a relationship between personality and time perception. The experimental hypothesis predicts that ‘there is a negative correlation between extraversion and time perception’.
You may find it helpful to read about the Eysenck Personality Questionnaire (EPQ). It scores for extraversion and neuroticism. A sample of this data is used in the activity.
The following variables are used:
|Age||is generally recorded to rule it out as a confounding variable.|
|Gender||is usually recorded as a control variable.|
|Extraversion||is one of the three personality traits measured by the EPQ.|
|Neuroticism||is one of the three personality traits measured by the EPQ.|
|Estimation||is the time estimated by participants in the study.|
