📈 Empirical CDF (ECDF)
Empirical cumulative distribution: F(x) = fraction of the sample ≤ x; view the whole distribution and in-place quantiles without assuming a distribution
Data
Notes
· The ECDF plots the sample as a step curve F(x)=#(≤x)/n with no distributional assumption; it reads off "the proportion not exceeding a given value" and in-place quantiles (P50 is the median). Overlaying the normal CDF lets you judge at a glance how close the data are to normal.
· Quantiles use linear interpolation (type=7, matching common statistical software).
