Organizing Data in Tables

When survey results show how many men and women prefer different types of music, or how many students in different year groups choose various subjects, we need a clear way to organize this information. Two-way tables provide a systematic method to display and analyze data involving two variables.

These tables are like spreadsheets for probability - they help us see patterns and calculate chances from organized data.
