• Question 111:

  All of the following are characteristics of probability sampling EXCEPT:

  A. A specific statistical design is followed

  B. The selection of items from the population is determined solely according to known probabilities by means of a random mechanism, usually using a table of random digits

  C. The sampling error (i.e., the difference between results obtained from a sampling survey and results that would have been obtained from a census of the entire population conducted using the same procedure as in sampling survey) can be estimated, and, as a result, the precision of the sample result can be evaluated.

  D. Listing of selected sample on a priority basis on a sampling sheet

  Correct Answer: D

• Question 112:

  For example, if you are using a survey to gather patient satisfaction feedback by email, you would not send a survey to ever y patient. You would start by sending surveys to roughly 50 percent of the patients and see how many are returned.

  This limited survey allows you to determine the response rate. Assume that 25 percent of these patients return the surveys.

  The next task is to determine how representative of the total population these respondents are. To test this question, you need to develop a profile of the total population. Typically, this profile is based on standard demographics such as gender, age, type of visit, payer class, and whether the respondent is a new or returning patient. If the distribution of these characteristics in the sample is similar (within 5 percent) to that found in the total population, you can be comfort able that your sample is reasonably representative of the population. If the characteristics of the sample and the population show considerable variation, however, you should adjust your sampling plan.

  This example clarifies that:

  A. A well-drawn sample, therefore, should be representative of the larger population

  B. The basic purpose of sampling is to be able to draw a limited number of observations

  C. Sampling is probably the most important thing you can do to reduce the amount of time and resources spent on data collection

  D. Sampling consists of series of compromises and tradeoffs

  Correct Answer: A

• Question 113:

  Stratification is the separation and classification of data into reasonably homogenous categories, within the data, that are mutually exclusive and facilitate:

  A. Data collection efforts

  B. Discovery of patterns that would not be observed id data were aggregated

  C. Skills that are based more experience than knowledge

  D. Frustrated measurement process

  Correct Answer: B

• Question 114:

  Two key data collection skills satisfaction and sampling enhance any data collection effort.

  These skills are based more on ___________ and _____________ then on statistics, yet many healthcare professionals have received limited training in both concepts.

  A. Logic and reliability

  B. Relatedness and latest happenings

  C. Ethics and reliability

  D. Logic and clear thinking

  Correct Answer: D

• Question 115:

  Once you have resolved these issues, the data collection should go smoothly. Unfortunately, many quality improvement teams do not spend sufficient time discussing their data collection plans. They want to move immediately to data collection step.

  This haste usually guarantees that the team will: (Choose three.)

  A. Reschedule the time and cost

  B. Collect too much (or too little) data

  C. Collect the wrong data

  D. Become frustrated with the entire measurement journey

  Correct Answer: BCD

• Question 116:

  The data collection phase of the journey consists of two parts: (1) Planning for data collection and (2) The actual data gathering. A well-designed data collection strategy should address different analytical questions.

  Which of the following is/are the part of planning section for data collection? (Choose two.)

  A. Will the data add value to your quality improvement efforts?

  B. How often and for how long will you collect the data?

  C. Will collecting these data have negative effects on patients or employees?

  D. Do you have target and goals for the measures?

  Correct Answer: AB

• Question 117:

  The problem with using readily available, convenient data is that the data usually do a poor job of answering the questions necessary to access performance. Ten years ago, this "good enough" approach to data collection might have been acceptable. Today, however, because of the increasing demand to demonstrate effectiveness of care and efficiency of healthcare processes, this mindset is not acceptable. Performance quality and excellence do not occur because organizations do what they have always done or what is convenient.

  Most healthcare observers agree that:

  A. Specific measures should not be used in data collection

  B. Industry does not need perpetuation of status quo

  C. Quality improvement efforts definitely end up with a positive result

  D. Once you have resolved the issues, the data collection should go smoothly

  Correct Answer: B

• Question 118:

  Using the same operational definition becomes even more critical if you are trying to compare several hospitals or clinics in a system. When national hospitals are made, the operational definition challenge becomes extremely complex.

  All good measurements begin and end with _____________.

  A. An objective and an outcome respectively

  B. A vision

  C. An operational definition

  D. A milestone

  Correct Answer: C

• Question 119:

  A good operational definition: (Choose two.)

  A. Gives communicable meaning to a concept or an idea

  B. Is no doubt clear but somewhat ambiguous

  C. Is a decision-making criteria

  D. Enables consistently in data collection

  Correct Answer: AD

  The aim/s of quality circle activities is/are:

  A. Contribute to implement and development of the enterprise
