Interpreting Categorical and Quantitative Data

S.ID.1(9/10) 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.S.ID.2(9/10) Interpret differences in shape, center, and spread in the context of the data sets using dot plots, histograms, and box plots, accounting for possible effects of extreme data points (outliers).S.ID.3(+) 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.S.ID.4(9/10) Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.S.ID.5Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.S.ID.5a(9/10) Use a given linear function to solve problems in the context of data.S.ID.5b(9/10) Fit a linear function to data and use it to solve problems in the context of the data.S.ID.5c(+) Assess the fit of a function by plotting and analyzing residuals.S.ID.5d(+) Fit quadratic and exponential functions to the data. Use functions fitted to data to solve problems in the context of the data.S.ID.6(9/10) Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.S.ID.7(11) Compute (using technology) and interpret the correlation coefficient of a linear fit.S.ID.8(11) Distinguish between correlation and causation.
