Frequency Tables and Bounce Heights

This video is the third in a series on statistics for experimental design. It focuses on creating frequency tables using data from an experiment where a tennis ball is dropped from different heights. The video explains how to list values, make tally marks, and calculate frequencies for different data sets, specifically for heights of 10 cm, 20 cm, and 30 cm. The tutorial provides a step-by-step guide to organizing data into a frequency table, emphasizing the importance of tally marks and frequency numbers.

What topics were covered in the first two videos of the series?

• Measures of central tendency and variation

• Probability and distributions

• Hypothesis testing and regression

• Sampling methods and data collection
