Histogram
A histogram is a graphical representation of the distribution of numerical data, typically using bars to show the frequency of data points within specified intervals or bins. It is a fundamental tool in statistics and data visualization for understanding the shape, central tendency, and spread of a dataset. Histograms are widely used in fields like data analysis, machine learning, and scientific research to summarize and interpret large amounts of data.
Developers should learn about histograms when working with data analysis, visualization, or statistical modeling, as they help identify patterns, outliers, and data distributions in datasets. They are essential for exploratory data analysis (EDA) in machine learning pipelines, quality control in software metrics, and performance monitoring in system analytics. For example, use histograms to analyze response times in web applications or to visualize feature distributions in predictive models.
