A simple random sample is meant to be an unbiased representation of a group. It is considered a fair way to select a sample from a larger population since every member of the population has an equal chance of getting selected. You are interested in the average reading level of all the seventh-graders in your city. It would be very difcult to obtain a list of all seventh- graders and collect data from a random sample spread across the city. However, you can easily obtain a list of all schools and collect data from a subset of these. You thus decide to use the O convenience sampling method. 0 systematic sampling method. 0 cluster sampling method. Stratied random sampling is a method of sampling that involves dividing a population into smaller groupscalled O strata 0 class Q unbiased 0 cluster What is an unbiased sample? 0 Each member of a population is equally likely to be chose. 0 All of the above. 0 The sample is representative of the population. What are top advantages of using convenience sampling? 0 All of the above. 0 Inexpensive to create samples 0 Collect data quickly Absence of data pattern: There are specific data that don't have an arrangement in place. This data can be analyzed in an unbiased manner, using systematic sampling. O True O False
