The document outlines statistical properties including mean, mode, median, quartiles, percentiles, and range. It defines key formulas such as mean as the sum of values divided by n, and variance calculated from the differences from the mean. Standard deviation is presented as the square root of variance, emphasizing the relationship between these statistical measures.

1. Properties are:
Mean
Mode
Median
Quartiles
Percentiles
Range
Mean = Sum of values / n
Standard Variation = Sqrt( variance )
Variance = Sum ( X - Mean )^2 / n
Median = Middle Most Observation
Mode = Most Repeated Observation
Range = Maximum - Minimum
Solution
Properties are:
Mean
Mode
Median
Quartiles
Percentiles
Range

2. Mean = Sum of values / n
Standard Variation = Sqrt( variance )
Variance = Sum ( X - Mean )^2 / n
Median = Middle Most Observation
Mode = Most Repeated Observation
Range = Maximum - Minimum
