Are you a Lark or an Owl? Studies indicate that about 10% of us are morning people (Larks)
while 20% are evening people (Owls) and the rest of us are neither. In this question, we are
going to analyse these preferences among university students who participated in a research
study1 into the relationship between sleep habits and academic performance. Students were
given questionnaires and kept a sleep diary. One of the questions was 'Are you an early riser or
a night owl?' and one of the diary items was the time a student went to bed.
Comment on the shape of the distribution of bedtimes of Larks and Owls. In particular, briefly
describe each of the following characteristics:
•The shape of each distribution (peaks, symmetry, skewness);
• Whether there appear to be any outliers;
• The appropriate measures of central tendency and dispersion.
For full marks in this question, ensure that you justify your choice of measures to describe
central
tendency and dispersion, interpret these values in context and use them to compare Larks to
Owls to draw some overall conclusions.
