 Hamilton Apportionment Step 1: Calculate each state's standard quotaStep 2: Give each state it's lower quotaStep 3: Give the surplus seats to largest residues Jefferson Apportionment Step 1: Find a "suitable" lower divisorStep 2: Compute each state's modified quotaStep 3: Each state is apportioned its modified lower quota Adam's Apportionment Step 1: Find a "suitable" larger divisorStep 2: Compute each state's modified quotaStep 3: Each state is apportioned its modified upper quota Webster Apportionment Step 1: Find a "suitable" divisor Step 2: Compute each state's modified quotaStep 3: Each state is apportioned it's modified quota using conventional rounding Huntington Hill Apportionment Need both Upper and Lower quota, Geometric mean of U and L. If q < G, round down to L, otherwise round up.Ex: 3 x 4 = 12 --> sqrt of 12 = 3.5 --> roung up to 4 Convenience Sampling Commonly used, the selection of which individuals are in a sample is dictated by what is easiest or cheapest for the data collector. Simple Random Sampling The most basic form of random sampling. Based on the same principle of a lottery: any set of #s has an equal chance of being chosen. Stratified Sampling Breaks sampling frame into categories called "strata" and then randomly choose a sample from these strata. The chosen strata are then further divided into categories called substrata. Quota Sampling A systematic effort to force the sample to be representative of a given population through the use of quotas. Parameter The numerical info we would like to have Statistic Any kind of numerical info drawn from a sample of a parameter. 1 Standard deviation 68% 2 Standard deviation 95% 3 Standard deviation 99.7% Permutations nPr = Combinations nCr = Probabilities Normal Distribution   Q n The number of objects r The number of things you want to deal with Authormhirshfield ID140080 Card SetMath Midterm DescriptionMath Midterm Updated2012-03-06T22:25:13Z Show Answers
