Identify explanatory and response variables in situations where one variable helps to explain or influences the other. Make a scatterplot to display the relationship between two quantitative variables. Describe the direction, form, and strength of the overall pattern of a scatterplot. Recognize outliers in a scatterplot. Know the basic properties of correlation. Calculate and interpret correlation in context. Explain howcorrelation r is influenced by extreme observations.

Use r 2 to assess how well the line fits the data. Answer all of these questions. Interpret the standard deviation of the residuals and r 2 in context. 3 Assignment #1 is problems 47, 49, 54, 56, 58 Identify the equation of a least-squares regression line from computer output. Explain why association doesn’t imply causation. Recognize how the slope, y intercept, standard deviation of the residuals, and r 2 are influenced by extreme observations.
