Exam 1: Why Is My Evil Lecturer Forcing Me to Learn Statistics

Which of the following is an example of correlational research?

If maximum oxygen uptake (VO₂ max) was considered the independent variable, which of the following would be an appropriate dependent variable?

A group of researchers wanted to know whether a new portable, online gas analysis system provided an accurate measure of VO₂ max. To assess whether the VO₂ max measures were sufficiently accurate a group of participants performed an incremental exercise test using the new portable system. The test was then repeated one week later, but this time using Douglas bags. How would you define this type of validity?

Researchers wanted to examine the impact of a high-protein diet (e.g. Adkins diet) in a group of individuals who had been sedentary for a minimum of 20 years. A variety of physiological phenomena such as blood pressure and blood glucose concentrations were measured before, during and after the diet. How might you describe the research design of such a study?

How is a research hypothesis denoted?

Which of the following would be classed as a null hypothesis?

When describing the central tendency and dispersion of a data set, which of the following are acceptable formats? (You may select more than one option.)

What is the median distance jumped by the top 10 athletes (see Q15)?

Based on the data provided in Q15, calculate the z-score for the participant who finished third in the men's long jump final.

How would you conceptualize the measurement of blood pressure from a group of individuals on multiple occasions to see if the results were sufficiently similar?

If sport and exercise science students were asked to rank biomechanics, physiology, psychology, nutrition and research methods on a 1-5 scale, with 1 being the subject you like the most and 5 being the one you like the least, which level of measurement would it be?

How is a null hypothesis denoted?

Jessica Ennis won the Olympic heptathlon in London, but how did she perform in the 100 m hurdles, high jump and long jump compared with the other athletes? Using the data below, calculate Jess Ennis' z-scores for the three previously mentioned events. 100 m Hurdles

Which of the following examples would be considered as a continuous variable?

Examine the histogram of the qualifying distance for the men's long jump final at the London Olympics in 2012. How would you describe the appearance of the histogram?

The results of the men's long jump final at the London Olympics in 2012 are given below. What is the mean distance jumped by the top 10 athletes?

Which of the following is an example of experimental research?

Likert scales are frequently used in psychology to measure intangible phenomena such as motivation. If a five-point Likert scale was used to determine an individual's motivation to perform a specific task, which of following best describes the variable?

A 400 m race time would be considered an example of which level of measurement?

A prediction from a theory is known as a
