Across
- 4. a measure of linear correlation between two sets of data.
- 8. combination of multiple factors to assess how and to what extent they affect a certain outcome
- 9. difference between the observed value and the mean value that the model predicts for that observation
- 10. a relationship between two events where one event is affected by the other
- 15. a linear equation describing the relationship between an explanatory variable and an outcome variable
- 16. the proportion of the variation in the dependent variable that is predictable from the independent variable
- 18. gradient of a line
- 19. proposition made as a basis for reasoning, without any assumption of its truth
- 20. likelihood that the difference in conversion rates between a given variation and the baseline is not due to random chance
Down
- 1. false or fake
- 2. variable that influences both the dependent variable and independent variable
- 3. value of y where the line crosses the y-axis
- 5. The value the model predicts for the dependent variable
- 6. estimating or concluding something by assuming that existing trends will continue
- 7. the line that makes the vertical distance from the data points to the regression line as small as possible
- 11. a type of plot or mathematical diagram using Cartesian coordinates to display values
- 12. linear approach for modelling the relationship between a scalar response and one or more explanatory variables
- 13. estimates of the unknown population parameters
- 14. measure of the probability that an observed difference could have occurred just by random chance
- 17. named and identified as a category of comparison for the other categories
