  1. . . . aPENNY for theAGES. . . • Without looking for a particular penny, dig into the collection and grab ONE PENNY. Note its date, return it, and re-mix the collection. • Calculate the AGE of your penny, based on its mint date. For example, if the penny date is 1994, its age is 10 years (2014-1994). • Note the horizontal and vertical scales on the grid here and then record your penny’s age using a properly scaled X.

  3. Prob & Stat All Around Us! • In just the last week, it is likely that you encountered many aspects of probability and statistics in your life—at home, at work, at play, at school. Reflect on your last seven days and identify and describe two situations for which you used probabilistic reasoning or statistical reasoning. Be specific and descriptive! MAT 312

  4. Data Collection, Organization, Summary, & Analysis • In your small group, measure and record the following data for each group member. Use centimeters, rounded as indicated. • Height (shoes off; nearest whole centimeter) • Arm Span (arms extended parallel to floor, measure fingertip to fingertip; nearest whole centimeter) • Forearm Length (bend your arm at the elbow and measure the distance between your elbow crease and your wrist; nearest half centimeter) • Foot Length (shoes off; nearest half centimeter) MAT 312

  5. Data Collection, Organization, Summary, & Analysis • Transfer your measurements to the Excel spreadsheet set up for the class. • Within your small group, suggest some ways you might organize, summarize, and analyze these data. Summarize your discussion by writing a list of suggestions for discussion in the large group and submission to me. MAT 312
