Sullivan Essentials of Biostatistics in Public Health, 3e 4 Researchers have conducted a study and determined that the relative risk for developing a cold for individuals taking vitamin C is 0.47 when compared to the number of participants in the study who developed a cold while not taking vitamin C. This is an indication of which of the following? This indicates that people who took vitamin C were 47% more likely to catch a cold and that taking vitamin C makes people more susceptible to catching a cold. 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, making them less likely to catch a cold. 3 Which of the following most appropriately describes how the data from a cross-sectional study can be applied to a population? The data generated from a cross-sectional study can be applied to new or changing populations regardless of the amount of time that has passed since the study was conducted. The data generated from a cross-sectional study is only applicable to the original population of interest during the time that the study was conducted. The data generated from a cross-sectional study is applicable to any group of individuals with similar characteristics to the original population of interest. The data generated from a cross-sectional study is applicable to all individuals regardless of how much those individuals differ from the original population of interest. 2 The measure of uncertainty in a biostatistician's calculation of a particular outcome that may result from using a subset of the population to estimate the actual likelihood of the event occurring in the population as a whole is referred to by what statistical term? A chance error A systematic error A standard error A margin of error
