Descriptive Statistics involves summary measures such as mean, median, mode, range, standard deviation, and variance, as well as relationships between variables indicated by covariance and correlation.
The harmonic mean H of n numbers (x1,...,xn) is a measure of the average that is useful in specific circumstances, often where the average of rates is needed.
The arithmetic mean is the average of a set of numbers, calculated by dividing the sum of all the values by the total number of values.
Explore the concept of percentiles, a critical measure in statistics that indicates the relative standing of a value within a data set.
