Ans- true T/F: Understanding statistics makes one a more compassionate practitioner. Ans- true T/F: Keeping current with and critically appraising practice related studies and basing one's practice on evidence-based knowledge makes one a more ethical practitioner. Ans- true T/F: Because anyone can manipulate and distort statistics to support whatever point they are trying to make, it is best to ignore statistics rather than understand them Ans- false T/F: Learning about statistics pertains primarily to levels of practice dealing with policy analysis, and is of much less relevance to clinical practice.

Which of the following statements is true about published research studies? a. Some published research studies are fatally flawed. b. Being published ensures that a research study is scientifically rigorous. c. To be useful, research studies should be flawless. d. Although some published studies might have minor flaws, none will be fatally flawed Ans- a. Some published research studies are fatally flawed. Which of the following statements is true about selecting and implementing interventions supported by research evidence? a. The best scientific evidence should dictate the choice of intervention. b. No matter how strong an intervention's evidence might be, that intervention is likely to be inapplicable for some clients. c. Once the intervention is chosen and implemented, the EBP process is concluded. d. None of these Ans- b. No matter how strong an intervention's evidence might be, that intervention is likely to be inapplicable for some clients. Which of the following statements is true about research evidence? a. The best evidence available must be strong evidence based on studies that are virtually flawless. b. Interventions with very strong supporting evidence can be assumed to be effective when you implement them. c. If you can find no persuasive research evidence for any intervention applicable to your target problem, and you therefore must intervene in the absence of supporting evidence, the fifth stage of the EBP process (evaluating outcome) is no longer relevant or needed. d. No matter how strong the evidence that supports your chosen intervention may be, you should evaluate whether it achieves the intended outcome when you implement it. Ans- d. No matter how strong the evidence that supports your chosen intervention may be, you should evaluate whether it achieves the intended outcome when you implement it. Descriptive statistics: a.
