Mean, Median, and Outliers
Mean, Median, and Outliers is a free educational video by ProfKelley.It helps students in grades 9,10,11,12 practice the following standards HSS.ID.A.2,HSS.ID.A.3,HSS.ID.A.4.
1. HSS.ID.A.2 : Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets..
2. HSS.ID.A.3 : Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers)..
3. HSS.ID.A.4 : Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve..
