i have 2 set of scores.

1. 213,322,262,242,159,100,80,59,23,52,89,215

2. 30,30,29,27,25,23,22,23,25,28,29,30

in the first set, there are 2 outliers, 322 and 23.

i know that with a high outlier it drags the score up, with a low outlier it pulls it down. How can i explain the 2 extremes occuring at the same time?

and the range will be larger so that it can not represent the data range correctly. Is this correct?

thank you.
