... A factor is a variable that can take one of several levels used to differentiate one group from another. An experiment has a one-way or completely randomized design if several levels of one factor are being studied and the individuals are randomly assigned to its levels. (There is only one way to gr ...

... center and reduce a sample, substract the mean from each modality, then divide by the standard deviation. • The empirical frequency of an interval is the ratio of the number of values in that interval, to the total number of individuals. • The median is the smallest modality such that at least 50% o ...

Measures of Central Tendency
... Very different sets of numbers can have the same mean. You will now study two measures of dispersion, which give you an idea of how much the numbers in a set differ from the mean of the set. These two measures are called the variance of the set and the standard deviation of the set. ...

Addressing Onsite Sampling in Recreation Site Choice Models
... Independent experts (CIE 2006; NRC 2006) and politicians (Sergeant 2010) have noted the inherent bias associated with onsite sampling, leading some to conclude that federal expenditures should be curtailed until unbiased methods can be devised. Senator Charles Schumer’s recent criticism of the NOAA’ ...
