When we talk about frequency distributions and relative frequencies, there are some common misunderstandings.
Frequency vs. Relative Frequency: Many people think these two terms mean the same thing. But they're different! Frequency is just the number of times something happens in each category. Relative frequency shows how much that category is compared to the total. For example, if you count 20 people who like chocolate ice cream out of 100 total people, the relative frequency would be , which means 20%.
Distribution Shape and Data Type: Some folks believe that frequency distributions can only show numbers. But that’s not true! You can also show categories with frequency distributions. For example, if you ask students about their favorite ice cream flavors, you could make a frequency distribution that includes categories like chocolate, vanilla, and strawberry.
Summation of Relative Frequencies: Another confusion is thinking that all relative frequencies have to add up to 1. While this is usually true, it’s really important to make sure you define your groups clearly and include all the data you collected.
By clearing up these misunderstandings, we can better understand how to use frequency distributions and relative frequencies in statistics!
