The relative frequency of a data class is the percentage of data elements in that class. The relative frequency can be calculated using the formula f i = f n f i = f n, where f f is the absolute frequency and n n is the sum of all frequencies. f i = f n f i = f n. n n is the sum of all frequencies. In this case, n = 2+1+3+ 2 = 8 n = 2 + 1 + 3 ...

Explanation: Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
