Explain what is meant when it is said that "data vary". How does the variability affect the results of statistical analysis? Choose the correct answer below. A. Saying "data vary" means that the values of the variable change from individual to individual. In addition, certain variables can change over time for certain individuals. Because data vary, two different statistical analysis of the same variable can lead to different results. OB. Saying "data vary" means that the values of the variable change every time they are observed. Because data vary, each statistical analysis of a given variable will lead to different results. OC. Saying "data vary" means that examining different types of subjects will yield different data, such as examining a person and examining a car. Because data vary, it is impossible to compare different types of subjects, such as comparing people and cars. OD. Saying "data vary" means that observations can be measured with fractions or decimals instead of only integers. Because data vary, it is important to make sure to accurately account for fractional observations.
