Across
- 5. Mistakes in the results that are not due to chance but rather to flaws in the design or execution of the study.
- 6. A non-random method where participants are chosen based on their easy accessibility to the researcher.
- 8. The difference between the results obtained from a subset of a group and the results obtained from surveying the entire group, arising from chance variations in the selection process.
- 11. A list or other representation of the elements belonging to the group from which the selection for a study is made.
- 13. A probability method where the entire group is divided into subgroups based on shared characteristics, and then a random subset is drawn from each subgroup.
- 14. The entire group of individuals, items, or data points of interest in a study, sharing a common characteristic.
- 16. A method of selection where the likelihood of any specific member of the entire group being chosen is unknown, often relying on personal judgment.
- 17. The process of selecting a subset of individuals or items from a larger group to make inferences about the entire group.
- 18. The specific group of individuals or items that the researcher is interested in studying and about which conclusions will be drawn.
- 19. A method of selection where every member of the entire group has a known and nonzero chance of being included in the study.
- 20. A single member or a group of members chosen for inclusion in a study.
Down
- 1. Inaccuracies in the results due to some members of the initially selected subset not participating in the study
- 2. A probability method where the selection process involves first choosing larger groupings and then selecting elements within those groupings.
- 3. A probability method that combines different techniques, often involving the random selection of geographic areas in successively smaller units.
- 4. An investigation that includes every single element that makes up the entire group under study.
- 7. A non-random method where an experienced individual selects participants based on their knowledge or belief about the characteristics of the group.
- 9. A non-random method where participants are selected to ensure that certain subgroups within the group are represented according to a predetermined proportion.
- 10. A probability method ensuring every element in the entire group has an equal chance of being included in the subset.
- 12. A non-random method where initial participants help the researcher identify and recruit additional participants through referrals, useful for studying rare groups.
- 15. A probability method where a starting point is chosen randomly on a list, and then every nth element is selected thereafter.
