Summary paragraph:
In this video, we move from raw data to organized frequency distributions, demonstrating how to create tables and graphs for both categorical and quantitative variables. Using the Dog Toys dataset, we explore how to calculate simple frequencies, relative frequencies, and percent frequencies. We also introduce binned frequency tables for scale data and crosstabulations to compare variables such as breed and toy durability. By the end of this lesson, you will understand how frequency distributions form the foundation for statistical thinking, business analysis, and data visualization. This lecture supports students in QBA 237 Basic Business Statistics and will prepare you for future statistical methods.
