The correct answer is: A. Descriptive analysis can be more useful for defining future studies.
Descriptive analysis is the process of organizing, summarizing, and presenting data in a way that helps you understand what it means. It can be used to describe the characteristics of a population, to identify patterns in data, and to make comparisons between groups.
Descriptive analysis can be useful for defining future studies by helping you to identify the key variables that you want to study, to develop hypotheses about the relationships between those variables, and to design a study that will test those hypotheses.
Correlation does not imply causation. This means that just because two variables are correlated, it does not mean that one causes the other. For example, there is a correlation between ice cream sales and shark attacks. However, this does not mean that eating ice cream causes shark attacks. It is more likely that both ice cream sales and shark attacks are caused by a third factor, such as hot weather.
Inference is the process of drawing conclusions about a population based on data from a sample of that population. Statistical models are used to make inferences about populations.
In conclusion, the correct answer is: A. Descriptive analysis can be more useful for defining future studies.
