  1. Studies generated from previous research studies in which the research is produced to validate findings, increase generalizability, and/or eliminate or minimize limitations
    Replication studies
  2. Statements of the disparity between what is known and what needs to be known and addressed by the research
    Problem statements
  3. Declarative and objective statements that indicate the general goal of the study and often describe the direction of the inquiry
    Purpose statements
  4. A question that outlines the primary components that will be studied and guides the design and methodology of the study
    Research question
  5. A type of research question that is posed to compare one or more interventions to specific outcomes
    Analytic question
  6. Research designed to quantify the strength and the direction of the relationship of two variables in a single subject or the relationship between a single variable in two samples
    Correlation studies
  7. Studies planned by the researcher for collection of primary data for the specific research and implemented in the future
    Prospective studies
  8. A study conducted using data that have already been collected about events that have already happened. These secondary data were originally collected for a purpose other than the current research
    Retrospective study
  9. Retrospective studies are less expensive than prospective studies and are often good starting points for exploratory research questions.
  10. Prospective studies are indicated by research questions that focus on conditions that occur often and with relatively short follow-up periods
  11. Analytic studies are logical for questions answered with numbers or with measurements
  12. A restatement of the research question in a form that can be analyzed statistically for significance
  13. Two essential aspects of a good hypothesis are:
    • A statement of an expected relationship
    • An identification of a direction of interest
  14. A statement of the research question that declares there is no difference between groups
    Null hypothesis
  15. A two-sided statement of the research question that is interested in change in any direction
    Nondirectional hypothesis
  16. A one-sided statement of the research question that is interested in only one direction of change
    Directional hypothesis
  17. Sometimes called two sided hypotheses, these are appropriate for exploratory research questions or randomized trials of interventiosn.
    Nondirectional hypothesis
  18. These are more rigorous tests than directional hypotheses
    Nondirectional hypothesis
  19. Appropriate for research questions in which there is a great deal of literature or empiracal support for an existing relationship.
    Directional hypothesis
  20. Directional hypothesis tests are more liberal than nondirectional ones
