Statistics Colloquium
April 8 (Fri) 11 a.m.
Room 242 Bernhard Center

Fair or not fair? (A classroom activity to introduce the sampling distribution of proportions.)

Presenters: Tina, Kyle, Leonard, and Yao
Western Michigan University

Students will be asked to do a data collection activity by flipping coins in groups and record the number of heads and tails. Instructor should record the data from each group and plot frequencies in excel. The plotted graph will be compared with the bell curve in order to introduce the concept of Central Limit Theorem. The result of this activity can also be used in getting probabilities (normal approximation) and constructing confidence intervals. Surface will be used to illustrate the empirical rule and ranges of the confidence interval. This can be extended to “comparing two proportions” by randomly dividing the samples into two groups as "fair" and "not fair" group.
All statistics students are expected to attend.
