Sampling Design

Sampling Design. Sampling. The process of obtaining information from a subset (sample) of a larger group (population) The results for the sample are then used to make estimates of the larger group Faster and cheaper than asking the entire population Two keys Selecting the right people

Overall sampling protocol

Overall sampling protocol. The aims are to carry out the 9 sampling programs (along with individual programs) at (as far as possible) each of the 9 study sites (3C, 3R, 2B, 1I). The sampling procedure should be identical or similar at each study site, to

Sampling Design

Sampling Design. But First a Sampling Experiment. Each group of students should: 1. Pull 5 candies out of the bag 2. Weigh the candies 3. Write down the weight 4. Put the candies back in the bag!! 5. Pass the scale and bag to your neighbors 6. Silently multiply the weight of the 5 candies by 20.
