1.For 10 pairs of data, the correlation coefficient is computed to be r = -1. Wht do you know about the scatter diagram?
2.You are considering the most expensive purchase that you are likely to make: the purchase of a home. Identify at least five different variables that are likely to affect the actual value of a home. Among the variables that you have identified, which single variable is likely to have the greatest influence on the value of the home? Identify a variable that is likely to have little or no effect on the value of a home.
1. r = -1 indicates perfect predictability, where one variable increases while the other decreases.
2. What variables do you want to consider that would effect your purchase? Location and number of square feet might be a start. What others would you consider?
