A frequency distribution shows a summarized grouping of data divided into mutually exclusive classes and the number of occurrences in a class. So the Frequency is 4. To find the cumulative relative frequency, add all of the previous relative frequencies to the relative frequency for the current row. Frequency and period are intrinsically related; frequency counts the number of waves passing a fixed point per second, while period measures the time taken for one complete wave to pass a fixed point. If you need to calculate the frequency from the time it takes to complete a wave cycle, or T, the frequency will be the inverse of the time, or 1 divided by T. 5 kHz = 4.
