PySpark and AWS: Master Big Data with PySpark and AWS - Solution (Select, Withcolumn, Filter)

The video tutorial guides viewers through a data manipulation task using Python and Pandas. It covers reading data from a CSV file, creating a DataFrame, adding new columns for total and average marks, filtering students based on their performance in specific courses, and displaying the results. The tutorial emphasizes practical coding techniques and provides step-by-step instructions for each task.

What is the first step in processing the student data for the quiz?

• Display the data in a table

• Filter students based on marks

• Read data from a CSV file

• Create a new column for average marks

How do you add a new column for total marks in the DataFrame?

• Use a select statement

• Use a filter statement

• Use the withColumn notation

• Use a groupBy statement

What operation is performed to calculate the average marks of students?

• Add obtained marks to total marks

• Divide obtained marks by total marks and multiply by 100

• Multiply obtained marks by total marks

• Subtract total marks from obtained marks

Which condition is used to filter students who scored more than 80% in the OOP course?

• Course is not equal to OOP

• Course is equal to Cloud and average is greater than 80%

• Course is equal to OOP and average is greater than 80%

• Average is less than 80%

What is the purpose of the filter statement in the context of the OOP course?

• To add a new column

• To calculate total marks

• To select specific columns

• To filter students based on course enrollment and marks

What is the minimum percentage required to filter students in the Cloud course?

• 60%

• 50%

• 80%

• 70%

Which statement is used to filter students who scored more than 60% in the Cloud course?

• Join statement

• Select statement

• GroupBy statement

• Filter statement

What is the final step in processing the student data for the quiz?

• Calculate the average marks

• Add a new column for total marks

• Filter students based on course

• Print the names and marks of students

How can you display only the names and marks of students from a DataFrame?

• Use the filter statement

• Use the select statement

• Use the withColumn statement

• Use the groupBy statement

What is a limitation of Databricks when displaying data?

• It can only display the first 10 rows

• It can only display the first 20 rows

• It can only display the first 50 rows

• It can only display the first 100 rows
