A set of data can be described with a frequency distribution. There are two types of frequency distributions: Grouped and Ungrouped (“Psychological statistics. Frequency Distributions”, N.p.). Continue reading

Relative frequency – is how often something happens divided by all outcomes.
Example 1:
We have the frequency distribution of the chips “Pringles” at 40 different shops. Continue reading
As an example of the cumulative distribution, we will build and analyze the cumulative frequency distribution for rolling two standard number cubes.
Frequency is the measure of how how often an event appears. The frequency distribution table is a tool which can help in comparing the frequencies of different events occurrence. There are two type of frequency distributions which are used in statistics: grouped frequency distribution and ungrouped frequency distribution. The first one is utilized for a high quantity of data, when it is impossible to list all of them in the table (“Grouped Frequency Distributions”, 2016). Continue reading
