... Does power corrupt decision making? “Absolutely” according to an article in The Economist (January 23-29, 2010). In an experiment described by the article, a group of 15 volunteers were primed to feel powerful and then asked to roll two 10-sided dice (each having sides 0-9) and combine the results t ...

Variance and standard deviation (ungrouped data)
... In this leaflet we introduce variance and standard deviation as measures of spread. We can evaluate the variance of a set of data from the mean that is, how far the observations deviate from the mean. This deviation can be both positive and negative, so we need to square these values to ensure positi ...
