A. True. Statistical studies are not concerned with understanding the sources of variability in data, only with describing the variability in the data. Descriptive statistics help researchers determine the type of statistical methods to use in their research.
B. False. Statistical studies are concerned with neither understanding the sources of variability in data nor describing the variability in the data. Finding measures of the middle and trends are the only research objectives in statistical studies.
C. False. Statistical studies are not concerned with describing the variability in the data, only with understanding the sources of variability in the data. Understanding the sources allows researchers to determine what statistical methods to use in their studies.
D. False. Statistical studies are concerned with both describing the variability in the data and understanding the sources of variability in data. Understanding the sources allows researchers to control it and reach better conclusions.
