Understanding Frequency and Two-Way Tables in Statistics

The video tutorial covers the concepts of frequency and two-way tables. It begins with an explanation of frequency and relative frequency using a survey of students' favorite colors. The tutorial demonstrates how to calculate relative frequency and interpret it as probability. It then transitions to two-way tables, explaining their structure and use in exams. The video highlights the importance of ensuring rows and columns add up correctly and shows how to calculate probabilities from two-way tables.
