📚 Statistical Definitions

Mean: Sum of all values divided by count

Median: Middle value when data is sorted

Mode: Most frequently occurring value(s)

Standard Deviation: Measure of data spread from mean

Variance: Square of standard deviation

Range: Difference between max and min values

IQR: Interquartile range (Q3 - Q1)

Quartiles: Values that divide data into four equal parts

📊Formula

Mean = Σx/n | Median = Middle Value | Mode = Most Frequent | σ = √(Σ(x-μ)²/n)

💡How it works

Statistical measures help understand data distributions. Mean is the average, median is the middle value when sorted, mode is the most frequent value, and standard deviation measures spread from the mean.
