Outlier
The more spread apart the data, the higher the deviation.
A value much greater or much less than the others in a data set
The more spread apart the data, the lower the deviation.
The narrower spread apart the data, the higher the deviation.

Right Skewed Distribution
Symmetrical Distribution
Left Skewed Distribution
Asymmetrical Distribution
Best statistic equipped to deal with outliers, in that they are, mostly, unaffected by it.
If the outlier is high or low, it causes the mean to be high or low and makes it unreliable.
Greatly affected by outliers, as it can change the actual calculations by extreme numbers, up or down.

It uses data from entire populations to compare disease frequencies between same/different groups during the same or different points in time.
It cannot be used to test a hypothesis because of a number of limitations.
It consists of the carefully detailed report by one or more clinicians of the profile of a single patient.
Both a and b.
Follows both groups prospectively to compare the incidence of disease.

Is a part of observational studies which comes under analytical studies.
