In statistics, it's really important to know the difference between absolute and relative frequencies. This helps us understand data better.
Absolute Frequency: This is simply how many times a specific value or category appears in a group of data. For example, if there are 100 students and 30 of them got an 'A' grade, the absolute frequency of 'A' grades is 30.
Relative Frequency: This tells us what part of the whole that count represents. We find it by dividing the absolute frequency by the total number of items. So, in our example, the relative frequency of 'A' grades would be 30 divided by 100, which is 0.30 or 30%.
In short, absolute frequency gives us a straight count of something, while relative frequency helps us understand how that count fits into the bigger picture. This makes it easier to see how different pieces of data relate to each other.
