... Note that the χ2 curve becomes more symmetrical as the degrees of freedom increase. Appendix Table A-5 gives the χ2 values which have certain specific cumulative probabilities for various degrees of freedom. Since the χ2 distribution is related to a measure of dispersion from a sample, it has many ...

... Every time you make a measurement, there is an uncertainty associated with it. This uncertainty is composed of two parts: random, uncontrollable errors and systematic or controllable errors. The random errors are described by the precision, or reproducibility of a measurement. Random errors give val ...

... A measure of location, such as the mean or the median, only describes the center of the data. It is valuable from that standpoint, but it does not tell us anything about the spread of the data. For example, if your nature guide told you that the river ahead averaged 3 feet in depth, would you want t ...
