Symbol Frequency

Symbol frequency refers to how often a specific symbol or character appears in a given set of data or text. For example, in a book, the letter 'e' may appear more frequently than the letter 'z'. Understanding symbol frequency helps in data compression, language analysis, and coding, as it reveals patterns and common elements within the data. Essentially, it’s a way to measure the popularity or commonality of each symbol within a sample, providing insight into the structure and content of the information.
