Understanding Statistical Measures

Mean (Average): The sum of all values divided by the count. Represents the central tendency of the data.

Median: The middle value when data is sorted. Less affected by outliers than the mean, making it useful for skewed distributions.

Mode: The most frequently occurring value(s). A data set can have one mode, multiple modes, or no mode.

Standard Deviation: Measures how spread out values are from the mean. Low values indicate data points cluster near the mean; high values indicate wide dispersion.

Variance: The square of standard deviation, another measure of data spread.

Range: The difference between maximum and minimum values, showing the total spread of the data.

Applications

Statistical analysis is used in scientific research, business analytics, quality control, finance, healthcare, education assessment, sports analytics, and social sciences. Understanding these measures helps interpret data accurately and make evidence-based decisions.
