The population is a group of interest, such as the people who filled out a recent survey about their age. The parameter is the descriptive measure of that population. So in this example, a parameter could be the average age of the people who filled out the survey.

differances between stationary population and stable population
The alternativehypothesis (Ha or H1) describes the population parameters that the sample data represent, if the predicted relationship exists. It is always the hypothesis of difference. That is as opposed to the null hypothesis (H0) that describes the population parameters that the sample data represent if the predicted relationship does not exist. See Basic Statistics of the Behavioral Sciences by Heiman.
A population survey, better known as a census, entails the collection of each unit in the population. In sample survey information is collected from a subset of the population. The subset, or sample, needs to be selected carefully so that it is representative of the whole population and, if that requirement is met, statistics based on the sample are good estimators for the corresponding population parameters.
This function will accept two parameters and return the difference between the first and second parameter. function diffBetween ( a, b ) { return a-b; } //end diffBetween
Population is total number of people who live in a geographical area
