Statistical Measures

Mean (Average)

Sum of all values divided by count

Mean = Σx / n

Median

Middle value when data is sorted

• •**Odd count**: Middle value
• •**Even count**: Average of two middle values

Mode

Most frequently occurring value(s)

• •**No mode**: All values occur equally
• •**Multiple modes**: More than one value ties

Range

Difference between maximum and minimum values

Range = Max - Min

Common Applications

• •**Education**: Grade analysis, test scores
• •**Finance**: Stock prices, market analysis
• •**Science**: Experimental data, measurements
• •**Quality Control**: Product specifications, tolerances
• •**Sports**: Performance statistics, rankings

When to Use Each Measure

• •**Mean**: When data is normally distributed, no outliers
• •**Median**: When data has outliers or is skewed
• •**Mode**: When you need most common value
• •**Range**: Quick measure of data spread
