(choose chapter or problem)

The group should select two variables related to people on your campus that it believes have a strong positive or negative correlation. Once these variables have been determined, a. Collect at least 30 ordered pairs of data (x, y) from a sample of people on your campus. b. Draw a scatter plot for the data collected. c. Does the scatter plot indicate a positive correlation, a negative correlation, or no relationship between the variables? d. Calculate r. Does the value of r reinforce the impression conveyed by the scatter plot? e. Find the equation of the regression line. f. Use the regression lines equation to make a prediction about a y-value given an x-value. g. Are the results of this project consistent with the groups original belief about the correlation between the variables, or are there some surprises in the data collected?
