Common Core Algebra 1, Unit 4: One Variable Statistics
Each of the four lessons in Unit 4: One Variable Statistics comes with videos that teach the concepts, worksheets, practice packets, and corrective assignments. To begin the unit, viewers learn to calculate the mean, median, mode, and range and interpret their results in terms of the context. They then see how to determine the standard deviation of the data sets. The second installment focuses on data distributions. Scholars learn about symmetric, bimodal, and skewed distributions. They consider how the inclusion of an outlier will affect the mean, median, and standard deviation of a data set. The series continues with viewers learning how to create box plots, both by hand and using a graphing calculator. Additionally, they determine the interquartile range and interpret the value in terms of a situation. Young mathematicians learn to compare data distributions in the fourth lesson. They consider the shape of the distributions, identify any outliers, and compare the center and spread of the data. The unit review asks students to demonstrate what they have learned by creating and interpreting box plots and stem-and-leaf plots, determining the mean, median, mode, interquartile range, and standard deviation of data sets before comparing distributions using the shape, center and spread.
