  • 1. Researchers conducted a survey of a representative sample of over 1,000 drivers. Based on how often each driver engaged in road behaviour, a road rage score was given. The drivers were also grouped by annual income. The data were subjected to an analysis of variance, with the results summarized in the table.

  • Create a draft of the survey.

  •  Conduct a pilot pretest having another Learning Team in the class to provide feedback for your team. Chet will create a message thread for each team to place their survey in the Class Discussion Tab.

  •  Revise the survey based on the feedback provided by your classmates.

  • 2. Researchers investigated the effect of tablet surface area to volume on the rate at which a drug is released in a controlled-release dosage. For six similarly shaped tablets with different weights and thicknesses, the diffusional drug release rate (percentage of drug released divided by the square root of time) was determined. The experimental data are listed in the table. Complete parts a through d.

Think of this as a progress report to the CEO. He/She has provided your resources to conduct your research and you have just completed the deployment of your survey with some raw data BUT your analysis is not completed! This is to provide the CEO a quick touch point informing them how everything went, what are your initial thoughts, showing them your raw results
