This article introduces descriptive statistics as a method for organizing and presenting raw data to reveal underlying patterns. It differentiates descriptive statistics from inferential statistics, explaining that the former summarizes existing data while the latter makes predictions about larger populations based on samples. The guide details key concepts including population versus sample, types of data (categorical and numerical), measures of central tendency (mean, median, mode), and measures of dispersion (range, variance, standard deviation). It also touches upon data shape analysis using skewness and kurtosis, and data visualization techniques. AI
