What is relative c********* frequency distribution?
Answers
By cumulative frequency corresponding to a particular value of the variable, we either mean the number of observations less than or equal to (\leq ) that value or the number of observations greater than or equal to (\geq ) that value. The former is known as the cumulative frequency of less than type and the latter is known as the cumulative frequency of greater than type.
Thus, cumulative frequency of less than type for a particular value of the variable is obtained by cumulating or adding the frequencies of all values less than that value upto the frequency that particular value, i.e., by adding its frequency to the frequencies of all the values smaller than that value.
Similarly, cumulative frequency of greater than type for a particular value of the variable is obtained by cumulating or adding the frequencies of all values greater than that value, starting from the frequency that particular value, i.e., by adding its frequency to the frequencies of all the values greater than that value.
Specification of the different values of the variable together with the corresponding cumulative frequencies is called a cumulative frequency distribution which is generally represented in the form of a table where the values of the variable are written in order.
Cumulative Relative Frequency is the same as Cumulative Frequency; just that in case of Cumulative Relative Frequency, as the name suggests; we add or cumulate the relative frequencies instead of the simple frequencies.
