What is a feature of predictive analysis?

Predictive analysis is centered around the use of statistical techniques to forecast outcomes based on historical data. One of its key features is the application of various analytical processes that can identify trends and establish relationships among variables. Techniques such as linear regression and decision trees are fundamental to predictive analysis; they help in modeling the relationship between dependent and independent variables to make future predictions.

Linear regression is particularly useful for predicting a continuous outcome based on one or more predictor variables, while decision trees can model both categorical and continuous outcomes, providing a clear visual representation of decision-making logic. The ability to leverage these methods allows businesses and analysts to derive insights from data patterns, making B the correct answer in the context of predictive analysis features.

In contrast, the other options do not align with the principles of predictive analysis, which inherently involves the use of historical data and both qualitative and quantitative data, as well as the realities of working with diverse datasets that may include outliers.
