D) A minority group
Ans: A
Complexity: Easy
Ahead: What is Biostatistics?
Subject: Chapter 1

A) Chance error
B) Sampling error
C) Standard error
D) Margin of error
Ans: A

Subject: Chapter 1
3. Which of the following most appropriately describes how results from analysis of a cross-sectional study can be generalized to a population?
A) Results generated from a cross-sectional study can be generalized to new or changing populations regardless of the amount of time that has passed since the study was conducted.
B) Results generated from a cross-sectional study can only be generalized to the original population of interest during the time that the study was conducted.
C) Results generated from a cross-sectional study can be generalized to any group of individuals with similar characteristics to the original population of interest.
D) Results generated from a cross-sectional study can be generalized to all individuals regardless of how much those individuals differ from the original population of interest.
Ans: B
Complexity: Moderate

Subject: Chapter 1
4. Researchers conducted a study and reported that the relative risk for developing a cold is 0.47 for individuals taking vitamin C as compared to individuals not taking vitamin C. This is an indication of which of the following?
A) This indicates that the individuals taking vitamin C were 47% more likely to catch a cold and that taking vitamin C makes people more susceptible to catching a cold.
B) This indicates that the individuals taking vitamin C were 47% less likely to catch a cold and that taking vitamin C has a protective effect.
C) This indicates that the individuals taking vitamin C were 53% less likely to catch a cold and that taking vitamin C has a protective effect.
D) Only relative risks above one are statistically significant, thus a relative risk ratio below one indicates there is no difference between the individuals who take vitamin C and those who do not in terms of their risk for catching a cold.
Ans: C
Complexity: Difficult
Ahead: How Are Risk Factors or Characteristics That Might Be Related to the Development or Progression of Disease Identified?
Subject: Chapter 1
5. Which of the following is the most important factor in determining the generalizability of a well-designed study?
A) The inclusion and exclusion criteria for the study
B) The randomization of participants for a study
C) The type of study being conducted
D) The presence of blinding throughout the study
Ans: A
Complexity: Difficult
Ahead: How Is the Effectiveness of a New Drug Determined?

True/False
1. True or False? Biostatistics is defined as the application of statistical principles in medicine, public health, or biology.
Ans: True
Complexity: Easy
Ahead: What Is Biostatistics?
Subject: Chapter 1
2. True or False? The data collected in a biostatistical study can be applied to any population regardless of race, class, and socioeconomic status.
Ans: False
Complexity: Easy
Ahead: What Are the Issues?
Subject: Chapter 1
3. True or False? A relative risk of 5.67 indicates that the group of individuals in the study exposed to the particular treatment or risk factor of interest are 5.67 times more likely to experience the observed outcome being studied as compared to those who are untreated or unexposed to the risk factor.
Ans: True
Complexity: Moderate
Ahead: How Are Risk Factors or Characteristics That Might Be Related to the Development or Progression of Disease Identified?
Subject: Chapter 1
4. True or False? Oftentimes it is more difficult to establish a relationship between a risk factor and a particular disease outcome among older adults because they also have other risk factors for disease.
Ans: True
Complexity: Moderate
Ahead: How Are Risk Factors or Characteristics That Might Be Related to the Development or Progression of Disease Identified?
Subject: Chapter 1
5. True or False? Randomization of clinical trial participants is important to ensure that the results of the clinical trial can be generalized to the population as a whole, and not just to the subgroup of individuals that participated in the trial.
Ans: False
Complexity: Moderate
