Encyclopedia > Statistical Distibutions of Ungrouped Data


A distribution at its most fundamental notion is a set of categories or numbers. Given a set of raw data (ungrouped data) set X, we have 5 descriptive distributions:
1)Value Distribution 2)Frequency Distribution 3)Relative Frequency Distribution 4)Cumulative Freuency Distribution 5)Cumulative Relative Frequency Distribution


The Value Distriubtion is the unique elements within that set. The Frequency Distribution are the frequencies(counts) of the values of the set X per Value. The Relative Frequencies are the frequencies per value divided by the total size of the data set X per Value. The Cumulative Frequency Distribution is the number of values less than or equal to a given value from the Value Distribution.The Cumulative Relative Frequency Distribution is the proportion of values less than or equal to a given value from the Value Distribution.


Example of a Quantitive Distribution: Suppose we have the Raw Data X={1,1,1,2,2,4,4,5,5,2,5,6,6}
