Question 1

The data display below is a

Accepted Answer

The data display is a histogram, which is commonly used to display continuous data. The bars represent the frequency distribution of a continuous variable, where the height of the bar indicates the frequency or count of observations falling within a certain range or bin.

Question 2

Looking at the data represented in the scatter diagram below, you would conclude that there is

Accepted Answer

There is a positive correlation between Variable A and Variable B. As Variable A increases, Variable B also tends to increase. There is a general trend in the direction of the points on the scatter diagram.

Question 3

Twelve new cases of a certain disease occurred during the month of August. If 4,000 persons were at risk during August, then the

Accepted Answer

Incidence is the number of new cases in a specific period divided by the population at risk. Here, 12 new cases among 4,000 people result in an incidence of 3 per 1,000 persons (12/4000 * 1000 = 3).

Question 4

You are trying to improve communications with your staff by posting graphs of signs statistics on the employee bulletin board. You recently calculated the percentage of employees spend on each of six major tasks. Because you would like the employees to appreciate each task as a percentage of their whole day, you will post these figures using a

Accepted Answer

A pie graph is the best choice because it displays proportions or percentages as slices of a circle, which makes it easy to see how each task compares to the whole day.

Question 5

The chart above shows a normal distribution. What percentage of the cases fall within the two lines showing the standard distribution between -1 and +1 on either side of the mean?

Accepted Answer

The standard deviation of a normal distribution is such that approximately 68% of cases lie within 1 standard deviation of the mean. Therefore, the percentage of cases falling between the two lines representing -1 and +1 standard deviations will also be approximately 68%.

Question 6

Harry H. Potter was admitted to your hospital to receive a second round of chemotherapy for an invasive tumor. Four days after admission, Harry complained of a sore throat and developed a fever. Harry's throat culture was positive for strep. His strep throat will be

Accepted Answer

Harry's strep throat is considered a nosocomial infection because it developed more than 48 hours after hospital admission, indicating it was acquired in the hospital.

Question 7

The graph below can best be described as

Accepted Answer

The graph has more than one peak or mode, indicating that there are multiple values/observations that occur frequently or with high frequency. This is characteristic of a multimodal distribution.

Question 14

You want to construct a data display for a frequency distribution. You will use a

Accepted Answer

The best choice for constructing a data display for a frequency distribution is a frequency polygon or histogram. Both methods are effective in displaying the frequency distribution of continuous data, with the frequency polygon showing the frequencies as points connected by straight lines, and the histogram showing the frequencies as bars. The choice between the two depends on the type of data being analyzed and personal preference.

Question 15

The primary difference between an experimental (randomized) clinical trial and other observational study designs in epidemiology is that in an experimental trial, the

Accepted Answer

In an experimental (randomized) clinical trial, the investigator determines who is and who is not exposed to the intervention or treatment being studied, whereas in other observational study designs, such as cohort and case-control studies, the exposure status is determined based on factors outside of the investigator's control, such as natural occurrence or self-selection by study participants. Additionally, in an experimental trial, participants are typically assigned to either a treatment or control group randomly, whereas other observational studies often involve selecting groups based on their exposure status or other characteristics.

Question 16

The ability to obtain the same results from different studies using different methodologies different populations is

Accepted Answer

Reliability refers to the consistency of results across different measures, methods, or samples. In other words, it is the ability to obtain consistent results from different studies. Validity, on the other hand, refers to the degree to which a measure or method accurately measures what it is intended to measure. Confidence and specificity are not relevant to this question.

Question 17

The time period of a facility's Institutional Review Board (IRB) or Independent Ethics Committee (IEC) registration with the Department of Health and Human Services (NHS) is

Accepted Answer

The time period of an IRB or IEC registration with the Department of Health and Human Services (NHS) is generally 3 years. This registration must be renewed every three years to maintain compliance with federal regulations for the protection of human subjects in research.

Question 20

You have been conducting productivity studies on your coders and find that 20% of their time devoted to querying physicians about missing or unclear diagnoses. Assuming your coders wi a 7-hour day, how many minutes do they spend per day querying physicians?

Accepted Answer

First, we need to calculate the total time spent each day on coding:

7 hours = 420 minutes

Then, we need to find the amount of time spent querying physicians:

20% of 420 minutes = 0.2 x 420 = 84 minutes

Therefore, the answer is C.
