Key Concepts

Standard Deviation

Standard deviation is the square root of the variance, offering a measure of dispersion that is in the same units as the original data. It indicates how far, on average, data points tend to deviate from the mean, making it easier to interpret relative variability.

Range

Range is a simple measure of dispersion in a data set, calculated as the difference between the maximum and minimum values. It provides an indication of the overall spread, although it does not account for how data values are distributed between these extremes.

Variance

Variance quantifies the spread of a set of data points by computing the average of the squared differences from the mean. It is an important measure of dispersion that reflects how much the data values deviate from the central value, with larger variances indicating greater spread.

Missing Data Handling

Missing data handling involves identifying and properly accounting for absent or incomplete information within a data set. This step is crucial to ensure that statistical measures such as range, variance, and standard deviation are computed accurately and reflect the true characteristics of the data.
