Learn why percentiles are useful for learning about data distribution.
- [Narrator] Percentiles are 100 equal groups…with the population of values divided across the groups.…Percentiles help us understand the distribution of data…by grouping values into equal sized buckets.…Discrete percentiles return a value…that exists in the column.…These are useful when you want to know the value…in the column that falls into a percentile.…Now continuous percentiles interpolate…the boundary value between percentiles.…So continuous percentiles are useful when you want to know…what is the value at the boundary…between two percentile buckets.…
