Consider iron levels in a population that have a mean of 15.5 gdL and a standard deviation of 1.6 gdL. You are measuring the iron levels in one patient. Question 1: Give an example of an iron level from the patient that would be considered unusual. Describe how you determined that such a level would be considered unusual, using the Empirical Rule Rather than one patient, you are now measuring iron levels from a group of individuals. Question 2: Assume a specific sample size....

Consider when you are listening to a new patient who says they have had a fever for 3 days. You would use your knowledge and experience with probability to come to a diagnosis. What changes those probabilities? Is it age, is it other symptoms, is it new study results? What is the source of these probabilities and what causes these probabilities to change? This discussion is not to debate diagnoses, but to focus on the sources and influences on probabilities. Solution: Probability takes int...

Many variables in medicine follow a normal distribution where there are approximately an equal number of values below the mean as above the mean. Describe two variables that would probably follow a normal distribution. Also note which of the two variables would be likely to have a larger standard deviation and why. As an alternative question, what are some other potential probability distributions in the health care field such as bimodal, skewed, or exponential and give variables that would p...

Step 4: Select one of the articles found through the search and be sure that a frequency distribution is shown somewhere in the article.  If possible, use "full text - PDF" option to glance through it.  A frequency distribution will have numeric classes such as 0-9, 10-19, 20-29 and so on.  It will not have classes such as female and male.  Be sure the classes are numeric.  The frequency may be presented as a table or a graph, either is fine. Step 5: Type answers to the following questions on...

Consider two different data sets and then for each data set, propose your idea of what graph would best represent the key information. For each, be sure to include the type of graph along with what would be shown on each axis. The key data in the first data set is a list of all the injuries that a clinic saw in a month. The other data set has key data on the number of minutes that each patient spent in the waiting room of a doctor's office. You can make assumptions about other information or var...

Present two different types of data, or variables, used in the health field.  Examples could be blood pressure, temperature, pH, pain rating scales, pulse oximetry, % hematotcrit, minute respiration, gender, age, ethnicity, among many others.  Then classify each of those variables as qualitative vs quantitative as well as nominal, ordinal, interval or ratio and justify your classifications.  Finally, explain one type of analysis that could be done with one or both of the variables you selected. ...
