2.9, 25.0, 1.2, 2.5, 5.1, 2.0, 5.5, 10.5, 28.0, 2.8, 4.8, 4.2

2. Do these measures have similar results? If not, what does the ordering suggest about the shape of the distribution?

3. Calculate (1) standard deviation, (2) range, (3) 30th percentile, (4) 60th percentile, (5) 3rd quintile, and (6) Interquartile range
