Formulas
Range = Max - Min
Sturges Rule: k = 1 + 3.3 log n
Interval = Range / k
Mean: Sum of all values / number of values
Median: Middle value after sorting
Mode: Most frequent value
Quartiles: Q1 = P25, Q3 = P75
Percentiles: Px = xth percentile
Deciles: Dx = xth decile
Theorems
Sturges' Rule for class intervals
Suitable Grade Level
Grades 10-12
