Professor Nickel has four labs and a lecture class. The numbers of students
in his classes are:
12, 10, 9, 68, 12
What is the most appropriate measure of center?

The median. (12).

Step-by-step explanation:

As there is one outlier ( 68)  the best measure is the median.

9. 10 12 and 12 are close together but 68 is way higher.

The median  is the middle number which is 12.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
