What is Data

The video tutorial discusses the significance of data in machine learning, explaining what data is, its various forms, and how it is organized into data sets. It covers the distinction between dependent and independent variables and emphasizes the importance of data in building effective machine learning models. The tutorial also explains how data sets are split into training and testing sets to evaluate model accuracy, with a common split being 70% for training and 30% for testing.

Describe how data sets are typically presented and what they consist of.

How can the choice of splitting data into training and testing sets affect a machine learning model?
