Question

Quizplus · Accepted Answer

A consecutive set of data points that gradually move away from the mean is known as a trend. This type of aberration indicates a systematic shift in the data rather than a random variation (outlier) or a sudden change (shift). Variance refers to the spread of the data, which is not relevant in this case.
