How are pandas range calculated?

Variability of Data with Pandas

Visualizations of data. Histogram.
Range = max – min.
Quartiles.
Outliers.
Deviation from mean = x_i – x_mean.
Mean absolute deviation = sum(x_i – x_mean) / n.
Squared deviation = (x_i – x_mean)^2.
Mean squared deviation = variance = sum((x_i – x_mean)^2) / n.

What is the formula for percentile?

Key Facts: Percentiles Percentiles can be calculated using the formula n = (P/100) x N, where P = percentile, N = number of values in a data set (sorted from smallest to largest), and n = ordinal rank of a given value. Percentiles are frequently used to understand test scores and biometric measurements.
