Across
- 2. a group or set chosen from a larger statistical population according to specified characteristics
- 5. two box and whisker plots on the same number line
- 9. describes a subject, and cannot be expressed as a number
- 11. data that can be counted or measured in numerical values
- 13. a probability sampling method where researchers select members of the population at a regular interval
- 14. a subset of a statistical population in which each member of the subset has an equal probability of being chosen
- 15. an outcome of a random experiment
- 16. a method of data collection used to gather information about people and their behaviors or opinions by asking them a list of questions
- 18. A selection that is chosen randomly (purely by chance, with no predictability)
- 20. The researcher chooses a sample that is readily available in some non-random way
Down
- 1. a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis
- 3. a discrete group of people, animals or things that can be identified by at least one common characteristic for the purposes of data collection and analysis
- 4. the process of drawing conclusions about a parameter one is seeking to measure or estimate
- 6. if the conclusion follows from the assumptions by applying legal mathematical operations to arrive at the conclusion
- 7. if its expected value is equal to the true value of the parameter
- 8. The researcher puts out a request for members of a population to join the sample, and people decide whether or not to be in the sample
- 10. their structure does not guarantee the truth of the conclusion
- 12. the difference between the expected value and the real value of the parameter
- 17. the study of the collection, analysis, interpretation, presentation, and organization of data
- 19. displays the five-number summary of a set of data
