Referenced from Module 1 Below:

The assignment this week is to collect quantitative data from your daily activities for a minimum of 10 days. Some examples of data to collect are:

  • The number of minutes you spend studying every day.
  • The time it takes to cook meals each day.
  • The amount of daily time spent talking on the phone.
  • The amount of time you drive each day.

In a paper (1–3 pages), describe the data you are going to collect and how you are going to keep track of the time. Within the paper, incorporate the concepts we are learning in the module including (but not limited to) probability theory, independent and dependent variables, and theoretical and experimental probability. Discuss your predictions of what you anticipate the data to look like and events that can skew the data. Collect data for at least 10 days. Do you think the data will provide a valid representation of these activities? Explain why or why not.
