  • www.newtonhelp.com
  • What are the characteristics of a population for
    which it would be appropriate to use
    mean/median/mode? When would the characteristics
    of a population make them inappropriate to use?

  • Exercise 10
  • What demographic variables were measured at the
    nominal level of measurement in the Oh et al.
    (2014) study? Provide a rationale for your
    answer.
  • What statistics were calculated to describe body
    mass index (BMI) in this study? Were these

  • www.newtonhelp.com
  • Explain the importance of random sampling. What
    problems/limitations could prevent a truly random
    sampling and how can they be prevented?

  • www.newtonhelp.com
  • How large would your population have to be for a
    sample to be appropriate (i.e., rather than
    measuring the whole population)?

  • Exercise 16 Understanding Independent Samples
    t-Test
  • What do degrees of freedom (df ) mean? Canbulat
    et al. (2015) did not provide the dfs in their
    study. Why is it important to know the df for a t
    ratio? Using the df formula, calculate the df for
    this study.

  • uophelp.com is now newtonhelp.com
  • www.newtonhelp.com
  • Researchers routinely choose an a-level of 0.05
    for testing their hypotheses. What are some
    experiments for which you might want a lower a
    -level (e.g. 0.01)? What are some situations in
    which you might accept a higher level (e.g. 0.1)?

  • Mayland et al. (2014) do not provide the degrees
    of freedom (df) in their study. Use the degrees
    of freedom formulas provided at the beginning of
    this exercise to calculate the group df and the
    error df.
  • What is the F value and p value for spiritual
    needpatient? What do these results mean?

  • Describe the error in the conclusion. Given
    There is a linear correlation between the number
    of cigarettes smoked and the pulse rate. As the
    number of cigarettes increases the pulse rate
    increases. Conclusion Cigarettes cause the pulse
    rate to increase.
