WebHere are the key differences between the two: Standard deviation: Quantifies the variability of values in a dataset. It assesses how far a data point likely falls from the mean. Standard error: Quantifies the variability between samples drawn from the same population. It assesses how far a sample statistic likely falls from a population parameter.
