Procedure/Learning Experience Activity The key to understand random sampling is to understand first the different types of it and know the reason why those kinds of sampling become random. Match the word from column A to its definition in column B. Column A 1. Simple 2. Systematic 3. Stratified 4. Cluster Column B a. methodical procedure b. to divide or arrange into classes c. a number of similar things that occur together d. having few parts; not complex Since you are already familiar with random sampling words, identify the random sampling used in each of the following situations Choose from simple, systematic, stratified and cluster. 1. A researcher writes the name of each student on a piece of paper, mixes the papers in a bowl, and draws 7 pieces of paper. 2. A researcher selects every 7th students from a list. 3. A researcher tells the class to count off, and then selects those numbers that are multiple of 7. 4. A researcher separates the list from boys and girls then draws 7 names per each gender. 5. A researcher surveys all students from 3 randomly selected classes out of 7 classes. Next Steps If you are to create your own research, will you use random sampling? Why or why not? If yes. what kind of random sampling are you going to use? If not, how will you obtain your samples?
