An outlier will pull the mean and median towards itself. The extent to which the mean is affected will depend on the number of observations as well as the magnitude of the outlier. The median will change by a half-step.

The median is least affected by an extreme outlier. Mean and standard deviation ARE affected by extreme outliers.

Calculate the mean, median, and range with the outlier, and then again without the outlier. Then find the difference. Mode will be unaffected by an outlier.

An outlier pulls the mean towards it. It does not affect the median and only affects the mode if the mode is itself the outlier.

An outlier can increase or decrease the mean and median It usually doesn't affect the mode

The mean is better than the median when there are outliers.

The median and mode cannot be outliers. For small samples a mode could be an outlier.

it messes up the mean and sometimes the median. * * * * * An outlier cannot mess up the median.

The mean. Or the mode.

The outlier is capable of affecting mean median mode and range it affects mean because the average has changed if affects median because you have to cross out 1 more letter it doesn't affect mode it does affect range because an outlier is a number that i far away from the other numbers * * * * * It does not affect the median.

There would be a difference to the median. The old number wouldn't be the median but the mode wouldn't change. If the outlier is a high value, it will cause the mean value to shift to the higher side, while a low valued outlier will drop the mean value to a lower number.
