(12 points) The Buteyko method is a shallow breathing technique developed by Konstantin Buteyko, a Russian doctor, in 1952. Anecdotal evidence suggests that the Buteyko method can reduce asthma symptoms and improve quality of life. In a scientific study to determine the effectiveness of this method, researchers recruited 600 asthma patients aged 18-69 who relied on medication for asthma treatment. These patients were split into two research groups: one practiced the Buteyko method and the other did not. Patients were scored on quality of life, activity, asthma symptoms, and medication reduction on a scale from 0 to 10. On average, the participants in the Buteyko group experienced a significant reduction in asthma symptoms and an improvement in quality of life. 1. The paragraph above describes a(n) OA. Observational study B. Experiment 2. What are the cases? O A. Research groups B. Ratings from 0 to 10 C. Asthma treatments D. Asthma patients 3. Match the variable to its type: a. Quality of life b. Activity level c. Age-? d. Asthma symptoms - ? e. Medication reduction ?

Explanation / Answer

1. B. Experiment

Clearly, the recruited asthma patients are being treated with the Buteyko dose. Hence the subjects are being experimented on. Hence it is an experiment.

2. D. Asthma Patients

Clearly, the cases are the asthma patients because they are the units with respect to which the experiment is carried on.

3. a. Numerical and discrete (Beause it will take value on set {0,1,2,...10}).

b. Categorical and ordinal (Because it will take values from High, Low, Medium etc. And these have notion of order associated with them )

c. Numerical and Discrete ( Because it can be 0,1,2,.... Only integers when measured in years.)

d. Categorical and non-ordinal ( Because it will be specific description of the symptoms clustered in categoris. Ofcourse, they dont have any notion of ordering associated with it)

e. Numerical Continuous (Becuase it is quantitative variable measure on a continuous scale of 0.1 mL least count)

4. B. Does the Buteykp method reduce symptoms and improve quality of life for asthma patients?

This is very clear from the objective of the study being carried out.
