Data outliers are observations that deviate significantly from the rest of the data in a dataset. They can be exceptionally high or low values compared to the majority of the data points and can skew statistical analyses or models if not appropriately handled. So, the correct answer is: C. A datapoint that differs significantly from other observations.
