Designing and Implementing Enterprise-Scale Analytics Using Microsoft Azure and Power BI — Question 114

You are using a Python notebook in an Apache Spark pool in Azure Synapse Analytics.

You need to present the data distribution statistics from a DataFrame in a tabular view.

Which method should you invoke on the DataFrame?

Answer options

• A. summary
• B. cov
• C. sample
• D. rollup

Correct answer: A

Explanation

The correct method to call for presenting data distribution statistics in a tabular format is 'summary', as it provides an overview of the DataFrame's statistics. The other options, such as 'cov', focus on covariance, 'sample' is used for obtaining a random sample of the DataFrame, and 'rollup' is for aggregating data, which do not serve the purpose of displaying distribution statistics.
