Question 2
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 have an Azure ML experiment that contains an intermediate dataset.
You need to explore data from the intermediate dataset by using Jupyter.
Solution: You add a Convert to ARFF module, and then add the Execute R Script module.
Does this meet the goal?

Question 4
You need to identify which columns are more predictive by using a statistical method.
Which module should you use?
Which module should you use?
Correct Answer: A
Question 5
You work for a company that has retail department stores.
You are developing an Azure Machine Learning experiment to predict seasonal sales.
You need to address a model overfitting issue by using the following two solutions:
* Solution 1: Controls the penalty for complexity, which, when successful, prevents overfitting
* Solution 2: Separates model selection from testing, causing a more conservative estimate of generalization Which method should you use for each solution? To answer, drag the appropriate methods to the correct solutions. Each method may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
