1. The correlation coefficient: a. Is a number with a range from -1 to 1 b. If there is no correlation, the coefficient is negative c. If the correlation coefficient is negative, it indicates a strong positive relationship between x and y d. All of the above 2. A positive straight-line relationship: a. Does not show anything relevant to either correlation or regression b. Shows the values of x increasing as the values of y decrease c. Shows no change amongst the variables d. None of the above 3. The independent variable is also known as the response variable. a. True b. False 4. The coefficient of determination is the value of the correlation coefficient represented by a. True b. False 5. A simple regression model uses a straight line to predict a numerical variable which is independent from the response variable. a. True b. False 6. The equation of the regression line: a. It is written in standard form b. It is written in point-slope form c. It is written in quadratic form d. It is written in slope-intercept form 7. Once we have a simple regression line, we can use it to predict values for the independent variable X and the dependent variable Y. a. True b. False 8. The assumptions we use to determine the validity of predictions include: a. The sample should be paired data, with two variables: x and y b. The standard deviation of each dependent variable must be exactly the same as for each of the dependent variables c. The sample is a random sample d. The sample is collected using a cluster sampling method 9. Outliers usually: a. Do not affect the correlation coefficient. b. Should be included when calculating the correlation coefficient. c. Should be identified before doing any calculation. d. Are usual values that are within 2 standard deviations from either side of the mean.
