Do you trust the Internet? You want to ask a sample of high school students the question "How mach do you trust information about health that you find on the Internet-a great deal, somewhat, not much, or not at all?" You try out this and other questions an a pilot group of 5 students chosen from your class. The class members are listed at top right. (a) Explain how you would use a line of Table $D$ to choose an SRS of 5 students from the following list. Explain your method clearly enough for a classmate to obtain your results. (b) Use line 107 to select the sample. Show how you use each of the digits. (TABLE CAN'T COPY)

Key Concepts

Pilot Study

A pilot study involves testing the survey instrument or sampling procedure on a small subset of the intended population before conducting the full-scale study. This preliminary step helps identify and correct any issues or ambiguities in the survey questions, ensuring the quality and reliability of the data that will be collected in the actual research.

Sampling Frame

The sampling frame is a complete list of all the individuals in the population from which the sample is to be drawn. In practice, it is important to have an accurate and comprehensive sampling frame to ensure that every member of the target population has a chance of being selected, which is essential for achieving a valid simple random sample.

Simple Random Sampling (SRS)

Simple random sampling is a method of selecting a sample in such a way that every possible subset of individuals from the population has an equal probability of being chosen. This method helps eliminate bias in the sample selection, ensuring that the study results can be more reliably generalized to the entire population.

Random Number Table

A random number table is a tool that contains randomly ordered digits which can be used to select subjects for a study. When using the table, a researcher preassigns unique numbers to each member of the sampling frame and then uses a specific line or block of random digits to correspond to these numbers, thereby choosing participants in an unbiased and systematic manner.
