I'm looking a single adjective or a short adjective phrase that refers to values that are either above or below an average. Consider this sentence:
Participants with scores above or below the average will receive special instructions.
I'd like to replace the that clause by a modifier structure EXPR:
Participants with EXPR scores will receive special instructions.
Roughly speaking, the expression should refer to values that fall within the ranges shaded blue in the following figure:
As you can see, the overall distribution of values may follow a bell curve, with an average of about 50 (dashed line). EXPR should apply to values in the blue-shaded areas, i.e. scores that are not between 40 and 60. Statistically speaking, more than 40 percent of all participant scores are in that area, so apparently I'm not really talking about participants with an unusual or unexpected score, or even an extreme or excessive score – these are participant scores that are just not average.
Any suggestions what I could use as EXPR?
