Across
- 1. A straight line when graphed
- 3. Numerical data, collection, organization, or analysis of data
- 5. sample A sample in which all members of a population have an equal chance of being chosen
- 6. Help us determine if a relationship exists and make predictions
- 10. Theory or statement
- 11. variable A variable that you need to now first, and is located on the X axis
- 12. The prediction involves a point inside the range of values of the independent variable
- 16. of best fit A curve that comes closest to the points on a scatter plot of a non-linear relation
- 17. trend Points all move up to the top right corner; starting at the bottom left corner
- 19. trend All points move down to the right; starting at the top left corner
- 21. hypothesis A theory that has opposite meaning of the original hypothesis
- 23. Error resulting from choosing a sample, that doesn't represent the whole population
- 24. A survey of all members of a population
Down
- 2. The value of the independent variable is external to the range of recorded data
- 4. of best fit A straight line that comes closest to the points on a scatter plot
- 7. data Data that was gathered for some other purpose
- 8. random sample Choosing members of a population at fixed intervals from a randomly selected number
- 9. time graph Shows an object's distance from a fixed point over a period of time
- 13. sampling Using a method that is not random to choose a sample from a population
- 14. Whole group of people or items being studied
- 15. data Original data that a resource gathers, specifically for an experiment or survey
- 18. Points that are arranged following a rule
- 20. A measurement that differs significantly from the data set
