Taylor Swift wants to find out how much fans enjoyed the Eras Tour shows. The company you work for has been hired to oversee the survey that will collect data from concert-goers.

1. Does this scenario represent an observational study or an experiment? Explain the differences between an observational study and an experiment. Justify your answer.

You have been asked to create four questions that will be included on the survey. Each question will need to record data at a different level of measurement (nominal, ordinal, interval and ratio).

1. Write a question that collects data corresponding to each level of measurement. Clearly label each question indicating the type of data the question will collect.
   • Ex: What is your height in inches? collects height in inches (ratio)

1. Reflect on your questions. Does the phrasing of your survey questions contribute to bias? If so, how? If not, give an example of a question that would contribute to bias on a survey.

The survey has been finalized, and the concert is about to begin. The stadium has different levels of seating -floor seats, lower-level seats, club level seats, and upper-level seats. You need to collect a sample that is representative of the population.

1. Describe the population. What are the challenges of sampling the entire population?
2. Describe how you would implement each sampling technique to get a representative sample of concert goers. For each sampling technique, what are the benefits and challenges?
   • Simple random sample
   • Stratified sample
   • Cluster sample
   • Systematic sample
   • Convenience sample
