Relative frequencies are calculated as _____________.

Answers

they’re calculated as percentages fractions and decimals

Relative frequencies are calculated as totals.

Here, we have,

In statistics, relative frequency refers to the proportion or percentage of times a particular value or category appears in a dataset relative to the total number of observations or data points.

It is a way to express the frequency of a value or category in relation to the whole dataset.

To calculate the relative frequency, you divide the frequency (number of times a value or category occurs) by the total number of observations or data points.

This gives you the proportion or percentage of occurrences relative to the total.

For example, if you have a dataset of 100 observations and a specific value appears 20 times, the relative frequency of that value would be 20/100 or 0.20, which is 20%.

So, relative frequencies are calculated as totals by comparing the specific frequency of a value or category to the total number of observations in the dataset.
