The frequency density is a the frequency of values divided by the class width of values. The area of each block/bar represents the total of frequencies for a particular class width. The width of the block/bar(along the x-axis) relates to the size of the class width.
The absolute frequency is the number of times that a certain value appears in a statistical study. It is denoted by fi. The sum of the absolute frequencies is equal to the total number of data, which is denoted by N. This sum is commonly denoted by the Greek letter Ï (capital sigma) which represents 'sum'. The relative frequency is the quotient between the absolute frequency of a certain value and the total number of data. It can be expressed as a percentage and is denoted by ni. The sum of the relative frequency is equal to 1.
