Frequency Tables
Frequency tables are a statistical tool used to organize and summarize data by counting the number of times a particular value or category appears in a dataset. They are commonly used in data science to provide a quick overview of the distribution of a variable and to identify patterns or trends in the data. Frequency tables can be used for both categorical and numerical data, and can be presented in a variety of formats, including simple tables, bar charts, and histograms. They are particularly useful for identifying outliers, detecting missing values, and assessing the quality of data. In addition, frequency tables can be used to calculate various statistical measures, such as mean, median, mode, and standard deviation.
