Descriptive statistics are essential tools for summarizing and understanding the basic characteristics of a dataset. They provide a way to describe the central tendency, spread, and overall shape of the data, making it easier to interpret and make informed decisions. Common measures include the mean, median, mode, range, variance, and standard deviation, all of which summarize different aspects of a dataset. These metrics help in identifying patterns, comparing datasets, and detecting outliers or anomalies.
