Frequency Analysis is a technique used to study the occurrence of elements within a dataset. It involves counting how often each element appears, which helps identify patterns or trends. This method is commonly applied in various fields, including cryptography, where it can reveal the structure of coded messages by analyzing the frequency of letters or symbols. In addition to cryptography, frequency analysis is also useful in data science and statistics. By understanding the distribution of data points, researchers can make informed decisions, detect anomalies, and improve predictive models. Overall, frequency analysis serves as a foundational tool for data interpretation and analysis.
