Document Summary
A general principle or set of principles that explains how a number of separate facts are related to one another. A florist wants to see if product x will extend the life of cut flowers so that they last longer. Involves selecting groups, upon which a variable is tested, without any random pre- selection processes. The teacher (the ones giving the shocks) were told to go home. Caused the emotional trauma thinking they may have killed someone. Used to give basic information about what we find. Uses statistics such as the mean, the standard deviation, the range (known as measures of central tendency) Variability- gives how spread out scores are from the mean (on a graph) Little variability- all bunched up close to the mean. Standard deviation is an index score- based on the distribution. Tells where, in relation to the general plot of scores, the score falls.
