PySpark and AWS: Master Big Data with PySpark and AWS - Average Age of Male and Female Students

The video tutorial explains how to calculate the average age of male and female students using Spark. It begins with an introduction to the problem, followed by implementing a mapper function to create key-value pairs based on gender. The tutorial then demonstrates using the 'reduce by key' method to group and sum ages by gender. Finally, it shows how to calculate the average age using map values, providing a comprehensive understanding of transformations in Spark.
