Relative Frequency and Percentages

The video tutorial covers the creation and conversion of frequency tables into relative frequency tables using decimals and percentages. It explains how to calculate relative frequencies by dividing the frequency of each category by the total number of observations. The tutorial also demonstrates converting these decimals into percentages and emphasizes the importance of ensuring that the total of relative frequencies equals 1.00 or 100%. The video concludes with a brief mention of the next topic, which is creating a two-way relative frequency table.
