This lesson follows the first batting average lesson. It requires all the batting averages for a team being already computed, or a list of chosen players.
Data Analysis, Statistics, and Probability
Mathematics instructional programs should include attention to data analysis, statistics, and
probability so that all students
Pose questions and collect, organize, and represent data to answer those questions
Interpret data using methods of exploratory data analysis
Develop and evaluate inferences, predictions, and arguments that are based on data
Take your list of batting averages and rank them in order. Create a
stem-and-leaf plot for your list. Once the plot is completed find
the mean, median, and mode of each league's batting average.
