A team of clinical psychologists investigated daily stress levels in individuals diagnosed with Generalized Anxiety Disorder (GAD). They asked a sample of 10 patients to rate their average daily stress over a fortnight on a scale from 1 (completely relaxed) to 10 (extremely anxious).
The results for the patients are presented in Table 1 below.
Calculate the measures of central tendency for the data in Table 1 and complete the table with your answers.
