The video tutorial covers the topic of data and statistics, emphasizing the seemingly disconnected nature of the subject. It reviews different types of survey questions, including open-ended and categorical questions, and explains how these questions yield different types of data, such as categorical and quantitative. The tutorial also delves into the subcategories of data, like nominal and ordinal, and discusses the importance of understanding the target population and sampling methods, including census and sample. The session concludes with an introduction to different sampling techniques.
