Writing with Descriptive Stats
EXAMPLE: Overall the company had another excellent year. We shipped
14.3 tons of fertilizer for the year, and averaged 1.7 tons of fertilizer
during the summer months. This is an increase over last year, where we
shipped only 13.1 tons of fertilizer, and averaged only 1.4 tons during
the summer months. (Standard deviations were as followed: this
summer .3 tons, last summer .4 tons).
Mean, Median, Mode
• The mean is the most common form of central tendency, and is what
most people usually are referring to when the say average. It is simply
the total sum of all the numbers in a data set, divided by the total
number of data points.
• The median is simply the middle value of a data set
• The mode is the most commonly occurring number in the data set.

Inferential
Poor example: "A t-test (t = 3.59) showed that the two groups were
significantly different (p<0.01).
Better example: Women scored higher than men on the aptitude test
(t = 3.89, p < 0.01).
