One Plus One Is How Many?
It is very easy to find an isolated statistic to support almost any position. It is also easy to misunderstand or misinterpret a statistic and then to perpetuate the resulting misinformation. And it is easy, perhaps too easy, to toss out a statistic in an attempt to add credibility to an objection.
Here is a brief refresher of some basics of statistical analysis:
Mean or Average--To find the mean of a set of numbers sum the values and divide by the number of values.
Divide 746 by the number of values in the set (7) to find the mean/average which is 107.
Median--The median is the middle value in the set of numbers when ordered by rank.
77, 86, 93, 100, 112, 133, 145 The median is 100.
A median is used when a value at one end or the other of the ranking would skew the average either up or down.
Mode--The most frequently occurring value in a set of numbers.
