Document Summary
In 2007, the town of hoodare had a poverty rate of 10% Pct pt poverty rate change in hoodare = 10% +10% = 20% All possible (or hypothetically possible) observations, eg. the entire population of the us. A subset of the population, e. g. a cluster sample of the us population. When a characteristic can take on different values, we can call it a. For example, age in this classroom is a variable. For example, if measuring age, one student in this class would represent a single case and we would have about 77 total cases. A measure of central tendency, the avg can be calculated by summing the values (for each case) for a variable of interest and dividing by the total number of cases. Sometimes we must account for the fact that cases do not have equal importance. In other words, some cases might contribute more/less than others. In these instances, we use the weighted mean.
