CCEP – EBC QUESTIONS WITH CORRECT ANSWERS

CCEP – EBC QUESTIONS WITH CORRECT ANSWERS What are the 5 ?'s to ask for EBC? (5 A's) -Ask -Acquire -Appraise -Apply -Assess Types of Data Qualitative (Nominal or ordinal) Quantitative (Interval or Ratio) Components of EBC 1) Scientific-based care 2) Patient preference 3) Literature Nominal data data of categories only. Data cannot be arranged in an ordering scheme. (Gender, Race, Religion) Ordinal data data exists in categories that are ordered but differences cannot be determined or they are meaningless. (Example: 1st, 2nd, 3rd) Interval data Differences between values can be found, but there is no absolute 0. (Temp. and Time) Ratio data data with an absolute 0. Ratios are meaningful. (Length, Width, Weight, Distance) Discrete variable a quantitative variable that has either a finite number of possible values or a countable number of possible values (not able to be broken down) Discrete variable test -Chi-square (Ex: Number of children in home) Continuous variable A variable (such as age, test score, or height) that can take on a wide or infinite number of values. Continuous variable test Two groups: Paired t-test More than two groups: ANOVA Independent variable The experimental factor that is manipulated; the variable whose effect is being studied. Dependent variable The outcome factor; the variable that may change in response to manipulations of the independent variable. Incidence of disease the number of new cases of a disease in a given area or population during a given period of time -Acute -Longitudinal Prevalence of disease total number of existing cases with respect to the entire population -Cross-sectional -Chronic disease illness Mean difference a standard statistic that identifies the absolute difference between two groups when comparison is the same *Continuous data Standardized difference a standard statistic that identifies the absolute difference between two groups when the measure of outcome is different (outcomes are converted to create an effect size) Positive predictive value The probability that a person with a positive test result is truly positive refers to what value? Negative predictive value The probability that a person with a negative test result is truly disease free refers to what value? Positive likelihood ratio How likely is a positive test to be found in a person w/ a disease than without Negative likelihood ratio the likelihood that a negative test result will be obtained in a patient/client with the condition of interest as compared to a patient/client without the condition of interest
