Across
- 5. a description of how much scatter there is in the data away from the line or curve of best-fit
- 6. the lowest value that a prediction is likely to be
- 10. a piece of data that does not seem to fit into the overall pattern
- 12. the highest value that a prediction is likely to be
- 14. a unique best-fit line that is found by making the squares of the residuals as small as possible
- 17. an equation, table or graph can be used to interpret data that has not been seen yet
- 19. a measure of the strength of an association already determined to be linear (values between -1 and 1)
- 20. a hidden piece of information that was not part of the statistical study under investigation
Down
- 1. this is created in order to analyze the appropriateness of a best-fit model
- 2. a measure of the strength of a linear relationship and is usually expressed as a percent
- 3. if one variable in a relationship increases as the other one increases, the __ is said to be (+pos)
- 4. a prediction made outside the range of the observed data - often not reliable
- 7. the distance a prediction is from the actual observed measurement in an association (R=A=P)
- 8. a model of numerical two-variable data that helps describe the data and is used to make predictions
- 9. a spread of data on a graph that has no discernible pattern
- 11. the correlation coefficient which is a measurement of how much data is scattered around the LSRL
- 13. a relationship between two (or more) variables and can be displayed on a scatterplot
- 15. an example of this might be Hearing Loss due to Long-term Noise Exposure
- 16. a mathematical summary (often an equation) of a trend in data
- 18. this type of association can be linear or non-linear and can contain clusters of data
