Getting the best representative sample is essential for a good valid study. After all, bad data = bad decision making. Explain the relationship between sample sizes and sampling error. How does sampling error occur in survey research? An applied approach: The vice president of operations at Busch Gardens knows that 70 percent of the patrons like roller-coaster rides. He wishes to have an acceptable margin of error of no more than ± 2 percent and wants to be 95 per-cent confident about the attitudes toward the “Gwazi” roller coaster. What sample size would be required for a personal interview study among on- site patrons? (describe how you arrived at your number)
