Descriptive Analysis
Descriptive analysis is a statistical method used to summarize and describe the main features of a dataset, providing insights into its central tendencies, variability, and distribution. It involves techniques such as calculating measures like mean, median, mode, standard deviation, and creating visualizations like histograms or box plots. This analysis helps in understanding the basic characteristics of data without making inferences or predictions about a larger population.
Developers should learn descriptive analysis when working with data-driven applications, such as in data science, machine learning, or business intelligence projects, to explore and clean datasets before applying more complex models. It is essential for tasks like data preprocessing, identifying outliers, and communicating findings to stakeholders through clear summaries and visualizations. For example, in a web analytics tool, descriptive analysis can be used to report user engagement metrics like average session duration or page views.
