Descriptive Statistics
Descriptive statistics summarise and describe the main features of a dataset. They form the foundation of data analysis in science, business, and social research.
Key Measures
Mean: The arithmetic average — sum of all values divided by count.
Median: The middle value when data is sorted. Robust to outliers.
Mode: The most frequently occurring value.
Variance: Average squared deviation from the mean.
Standard Deviation: Square root of variance — measures spread in original units.
IQR: Interquartile range (Q3 − Q1) — spans the middle 50% of data.
