2. A researcher has a population of 100 third grade children from a local school district from which a sample of 25 children is to be selected. Each child's name is put on a list, and each child is assigned a number from 1 to 100. Then the numbers 1 to 100 are written on separate pieces of paper and shuffled. Finally, the researcher picks 25 slips of paper and the numbers on the paper determine the 25 participants. (PURPOSIVE. CONVENIENCE, SIMPLE RANDOM) 3.
