IB SEHS Topic 6.2 Study Design

Which procedure would assess the reliability of an experiment?

• Repeat the experiment to determine if the results remain the same

• Test the degrees of precision of the instruments

• Conduct similar tests that measure changes in the same dependent variable

• Determine how close the measurements are to the true value

Which is correct about the Physical Activity Readiness Questionnaire (PAR-Q)?

• PAR-Q is used to determine the possible health risks of an exercise programme

• The PAR-Q form helps to diagnose cardiac issues

• If a PAR-Q is completed, it confirms that there will be no risk of injury

• PAR-Q is a screening tool based on a person’s athletic performance in previous competitive events

What is a benefit of a maximal test?

• Typically, it is safer than sub-maximal tests

• Typically, it is more accurate than sub-maximal tests

• Typically, it is easier to recruit participants

• Typically, participants experience a quick recovery

What makes a fitness test reliable?

• It is repeatable.

• It is relevant to a given sport.

• It is inconsistent.

• It measures the factors that it is designed to measure.

Which terms apply to the use of the multistage fitness test to evaluate the muscular power of a 100 m swimmer?

• Reliable and valid

• Not reliable and not valid

• Not reliable but valid

• Reliable and not valid

What is a Physical Activity Readiness Questionnaire (PAR-Q) form used for?

• To determine the goals of the programme

• To ensure that it is safe for the person to undertake physical activity

• To determine the person’s favourite activities

• To establish a baseline so any improvements can be measured

What does PAR-Q stand for?

• Physical activity readiness questionnaire

• Physiological activity readiness quantifier

• Physiological assessment regularity quantifier

• Physical assessment readiness questionnaire

Which is correct with regard to study design?

• Validity is when you retest in similar conditions and achieve consistent results.

• A power athlete performing a vertical jump test with their eyes closed is an example of using a blind study.

• Reliability is when you undertake a test and it measures what you want.

• An endurance athlete doing the Cooper’s 12 Minute Run to test aerobic power demonstrates specificity.

What is the role of a Physical Activity Readiness Questionnaire (PAR-Q)?

• To collect general information about the participants.

• To identify health concerns and ensure the safety of participants.

• To record performance data on participants engaging in sport.

• To exclude participants from a research project.
