Question
t/f Histograms are often used to display categorical data, while bar charts are commonly used to display variables that fall on a measurable continuum. t/f Biostatistics is integral to the practice of public health because it allows public health professionals to accurately monitor and track the prevalence of disease within a population.
Incidence reflects the likelihood of developing a disease among a group of participants free of the disease who are considered at risk of developing the disease over a specified observation period; prevalence involves estimating the proportion of people who have disease at a point in time. t/f
If the odds of catching the flu among individuals who take vitamin C is 0.0342 and the odds of catching the flu among individuals not taking vitamin C is 0.2653, then the individuals not taking vitamin C are 7.7573 times more likely to catch the flu than individuals taking vitamin C. t/f
Case-control study, prospective cohort study, clinical trial, and retrospective cohort study are all examples of observational study designs. t/f

Explanation / Answer
Result:
t/f Histograms are often used to display categorical data, while bar charts are commonly used to display variables that fall on a measurable continuum.
False. (Histograms for continuous data and bar chart for categorical data)
t/f Biostatistics is integral to the practice of public health because it allows public health professionals to accurately monitor and track the prevalence of disease within a population.
True
Incidence reflects the likelihood of developing a disease among a group of participants free of the disease who are considered at risk of developing the disease over a specified observation period; prevalence involves estimating the proportion of people who have disease at a point in time. t/f
True
If the odds of catching the flu among individuals who take vitamin C is 0.0342 and the odds of catching the flu among individuals not taking vitamin C is 0.2653, then the individuals not taking vitamin C are 7.7573 times more likely to catch the flu than individuals taking vitamin C. t/f
True.
Odds ratio =0.2653/0.0342 =7.75731
Case-control study, prospective cohort study, clinical trial, and retrospective cohort study are all examples of observational study designs. t/f
False (clinical trial is experimental study)
