Task A:
i. The study design is cross sectional study.
According to the level of evidence framework, the study falls under the level four.
The study attempted to define an existing relationship between the physical
activity with the mental health in terms of depression and anxiety scores. In the
research study the probabilities of moderate to severe symptoms of depression and
anxiety has been compared with the absence of characteristic symptoms among
the respondents (Bélair et al. 2018).
ii. The measurement scale used for the measurement for the items such as “I am too
fearful or nervous” had been the respondents rating how effectively the statements
described their feelings with the use of statements such as ‘never or not true’,
‘sometimes or somewhat true’ or ‘often or very true’ along with Cronbach alpha
scale (Bélair et al. 2018).
iii. The measurement scale used for two different outcomes measures physically
active and physically inactive is the interval measurement scale. Interval
measurement scale can be defined as the numerical scale that analyses both the
order and the exact differences between the values. In this measurement scale,
distance is meaningful, and as in this case the measures were in time gaps, hence
the most applicable measurement scale in this case is the interval type (Bélair et
al. 2018).
iv. The odds ratio of 1.85 means that for the physically inactive population group the
odd chance is 1.85 for occurrence of depression and anxiety for individuals with
limited or no physical activity. The 95% confidence limit (1.42 to 2.41) states that
for every time the study is replicated with similar randomly selected population
