In the case of electrical current, frequency is the number of times a sine wave repeats, or completes, a positive-to-negative cycle. The more cycles that occur per second, the higher the frequency. Example: If an alternating current is said to have a frequency of 3 Hz (see diagram below), that indicates its waveform repeats 3 times in 1 second.
A frequency distribution shows a summarized grouping of data divided into mutually exclusive classes and the number of occurrences in a class. It is a way of showing unorganized data notably to show results of an election, income of people for a certain region, sales of a product within a certain period, student loan amounts of graduates, etc.

Frequency means the number of waves per second. Frequency refers to the number of times the alternating current (AC) switches between positive and negative in 1 second. This switching does not occur in direct currents (DC). The unit of frequency is hertz (Hz). For example, if a current changes between positive and negative 60 times a second, we ...
For a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given period of time. So while wave frequency refers to the number of cycles occurring per second, wave speed refers to the meters traveled per second. A wave can vibrate back and forth very frequently, yet have a small speed; and a wave can ...
Frequency and period. Frequency and period are inversely related. In other words: This means that if we know either the frequency or the period of a function, we can determine the other value. The period of a function is the time it takes the function to complete one full cycle.
Frequency definition: The property or condition of occurring at frequent intervals.
