But most data is well behaved enough that going two standard deviations away from the mean captures nearly all of the data.

We estimate and say that four standard deviations is approximately the size of the range, and so the range divided by four is a rough approximation of the standard deviation. First, it is a very quick estimate of the standard deviation.

The objects are made from ebony and other woods, brass, German silver, and plastic.

To see an example of how the range rule works, we will look at the following example.This is one of the most stable and most common relationships.Although both types are very different, they want rather similar things—security and predictability (Sixes) and stability and autonomy (Nines).They both want their lives to be built on solid, dependable values and for good, honest work to be rewarded.Both types tend to personify "middle of the road" values in their time and culture, to be dutiful, respectful of authority, and to abide by the rule of law.The parallel rule was superseded for most uses by the T-square in the 19th century, but navigators continue to use parallel rules in conjunction with gridded charts.The mathematics collections contain about twenty parallel rules and combination instruments, dating from the late 18th century to the late 20th century and ranging in length from 6 to 24 inches.On the other hand, there is a rebellious streak in Sixes and a counterculture streak in Nines that allows some of these couples to live on the fringes of society, to be unusual in their lifestyle and beliefs, to be free thinkers and unconcerned about conventional values and mores.More for Sixes and Nines than for most couples, much depends on their belief systems and the quality of their childhood experiences—and they are looking for a partner who will mirror this, including their own beliefs and reactions.If instead we first calculate the range of our data as 25 – 12 = 13, and then divide this number by four we have our estimate of the standard deviation as 13/4 = 3.25. Doesn’t it seem completely arbitrary to just divide the range by four? There is actually some mathematical justification going on behind the scenes.This number is relatively close to the true standard deviation and good for a rough estimate. Recall the properties of the bell curve and the probabilities from a standard normal distribution.
