Understanding Frequency Tables

The video tutorial explains how to set up and use frequency tables to organize data. It begins with an introduction to frequency tables, followed by a step-by-step guide on setting them up using a data set. The tutorial includes examples of tallying numbers and calculating frequencies, ensuring the total matches the data set count. A second example reinforces the process, and the video concludes with a summary of key points. The tutorial emphasizes the importance of organizing data and provides tips to avoid mistakes.

What is the primary purpose of a frequency table?

• To calculate the average of a data set

• To organize data and show how often each value occurs

• To find the median of a data set

• To display data in a pie chart
