What is Descriptive Statistics?
Descriptive statistics summarize and describe the main features of a dataset. They provide simple summaries about the sample and measures, forming the basis of virtually every quantitative analysis of data.
Key Categories
Central Tendency: Where the data clusters around (mean, median, mode)
Variability: How spread out the data is (range, variance, standard deviation)
Shape: The distribution pattern (skewness, kurtosis)
Position: Where individual data points stand (percentiles, quartiles)
