Frequency
Frequency refers to the number of occurrences of a particular event within a given time period. In data science, frequency is often used to describe the distribution of values within a dataset. This can be represented using a frequency distribution table or a histogram, which shows the frequency of each value or range of values in the dataset. Frequency analysis is also used in natural language processing to identify the most common words or phrases in a text corpus. In signal processing, frequency analysis is used to decompose a signal into its constituent frequencies, which can then be used to filter or modify the signal.
