A2.D.1.1: Use the mean and standard deviation of a data set to fit it to a normal distribution (bell-shaped curve).
A2.D.1.2: Collect data and use scatterplots to analyze patterns and describe linear, exponential or quadratic relationships between two variables. Using graphing calculators or other appropriate technology, determine regression equation and correlation coefficients; use regression equations to make predictions and correlation coefficients to assess the reliability of those predictions.
A2.D.2.1: Evaluate reports based on data published in the media by identifying the source of the data, the design of the study, and the way the data are analyzed and displayed.
