So on number one you want characteristics of a normal distribution, that's your bell curve, where the mean, median, and mode are all the same.
00:22
And that means it's also symmetric, where our skewed data looks something like this, where we have the mode and then three other lines.
00:47
So in this picture, the verbage you use is right skewed, so this one's a right, which means the median is between the mean and the mode, and the mean is greater than the median.
01:26
Or if it's left, it's the opposite, so the mode is on the right, the median is in the left, which means the mean is less than the median, and they're definitely not symmetric.

In your second question, describe a whisker plot.
02:00
Whisker plot looks like this.
02:09
Usually this is the minimum, the first quartile, the median, the second quartile, the third quartile, and you'll have above or below, and that's with a calculation within a quartile, which is the difference between third quartile and first quartile...
