  2. 4. individual data points that fall outside the overall pattern of the relationship
  3. 5. linear or non-linear
  4. 6. a chart that shows the relationship between two quantitative variables
  5. 10. positive, negative, or none
  6. 13. a measure r between -1 and 1 of the strength and direction of a linear relationship
  7. 14. variable that measures the outcome of a study
  8. 15. type of table of frequencies or relative frequencies between two categorical variables (no dash)

Down
  1. 1. the use of a regression line for predictions inside the interval (range)
  2. 3. a line that models how a response variable y changes as an explanatory variable x changes
  3. 7. the amount by which the predicted value of y changes when x increases by 1 unit
  4. 8. if knowing the value of one variable helps us predict the value of the other
  5. 9. way to describe how closely the dots in a scatterplot follow a pattern
  6. 11. the difference between an actual value of y and the value of y predicted by the regression line
  7. 12. a guess of what value the response variable y will have for a given value of x
