Practice Question Set 3

Dr Rocket conducts a study in Australia to measure the relationship between body weight and stress, using a number of variables such as Body Mass Index (BMI), level of stress, level of self-esteem and avoidance of sports. He obtains the following correlational data.

A correlation is expressed by a number from -1 to 1 and describes how strongly two items are related. For instance, a correlation of 0.8 between coffee drinking and memory suggests that an increase in coffee drinking would correspond to a similar increase in memory.

Note that Body Mass Index (BMI) is a weight-to-height measure; the greater the BMI, the greater the individual’s body weight relative to their height.

 

Q1. Which of the following conclusions can Dr Rocket draw?

a)      There is a strong negative correlation between BMI and level of self-esteem, suggesting that being overweight causes low self-esteem

b)     There is a weak correlation between level of stress and level of self-esteem, suggesting that the two variables have no relationship

c)      The results suggest that an increase in levels of stress is loosely related to an increase in BMI, and an increase in BMI is loosely related to an increase in stress levels

d)     Any person with a higher level of stress is likely to avoid sports slightly more than another person with a lower level of stress

 

Q2. Which of the following statements is false?

a)      According to Dr Rocket’s results, there is a moderate positive correlation between BMI and avoidance of sports, suggesting that an increase in avoidance of sports corresponds to an increase in BMI

b)     According to Dr Rocket’s results, there is a small positive correlation between level of stress and avoidance of sports, suggesting that an increase in stress levels slightly contributes to greater avoidance of sports

c)      According to Dr Rocket’s results, there is a very small positive correlation between level of self-esteem and level of stress, indicating that there is an extremely weak relationship between self-esteem levels and stress levels

d)     According to Dr Rocket’s results, there is a strong negative correlation between BMI and level of self-esteem, indicating that as BMI decreases, level of self-esteem tends to increase

 

 

The following passage is taken from a novel. Dr Schlosser is a general practitioner. He takes his time with each of his patients, making him popular among them. However, after attempting to carry out a complicated medical procedure, one of his patients (Mr Meier) dies. In this passage, Dr Schlosser talks to a specialist (Maasland), with Mr Meier’s widow (Judith) also present.

 

‘Yesterday  we ran through Mr Meier’s full case history with him,’ he said. ‘That’s  common practice in a euthanasia case. But if I’m right, it wasn’t you who  finally referred Mr Meier to us, was it, Dr Schlosser?’

I pretended  I had to think about it. ‘No, that’s right,’ I said.

Maasland ran  his finger back and forth across the sheet of paper he’d removed from the  folder. ‘I ask you that because it says here… yes, here it is.’ The finger  came to a stop. ‘Yesterday, Mr Meier stated that in October of last year he  came to you for a check-up.’

‘Could be.  He didn’t come in often. If he was in doubt about something. Or for a second  opinion. I was… I am a friend of the family.’

‘And why did  he come to see you in October, Dr Schlosser?’

‘I couldn’t  say. I’d have to look it up.’

Maasland  glanced at Judith, then back at me. ‘According to Mr Meier, you told him in  October of last year that there was nothing for him to worry about. Even  though by then he was already displaying the early symptoms of his illness.’

‘I wouldn’t  know about that, not off the top of my head. It’s possible that he asked me  about something then. Maybe he already sensed something and just wanted to  hear a comforting word.’

‘During that  particular consultation in October, Dr Schlosser, did you remove some tissue  from Mr Meier’s body? And did you then send that tissue to us for analysis?’

‘If I had, I  think I would remember that.’

‘Yes, I  would think so too. Especially since removing tissue is not entirely devoid  of risk. In the worst of cases, it can even accelerate the course of the  disease. I trust you’re aware of that, Dr Schlosser?’
