Question

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You are a data scientist using Azure Machine Learning Studio. You need to normalize values to produce an output column into bins to predict a target column. Solution: Apply an Equal Width with Custom Start and Stop binning mode. Does the solution meet the goal?

Explanation

Equal Width binning divides the value range into intervals of equal size regardless of how the data is distributed. If the data is skewed or has outliers, most records will cluster into a few bins while other bins remain nearly empty. This imbalance is problematic when using bins to predict a target column, as uneven bin populations reduce predictive signal and model quality. For prediction tasks, bin edges should ideally be chosen based on the target variable's distribution or information gain (e.g., Entropy MDL binning), not simply by dividing the numeric range equally.
