Statistics for Nursing A Practical Approach 3rd Edition Heavey Test Bank LATEST UPDATES.2023 1. Researchers study the impact of internalized bias on patient care. Nurses complete a survey which determines a score for their internalized bias from 0-100. Without knowing the internalized bias score, patients are asked to rank the subsequent care they receive from the nurse as poor, fair, good or exemplary. In this study your independent variable is measured at what level of measurement? a. Ratio. Ratio data is the highest level of measurement you can collect and gives you the greatest number of options for data analysis. Ratio data meets all the criteria for the nominal, ordinal and interval ratio, plus there is a point where it does not exist. 2. Researchers study the impact of internalized bias on patient care. Nurses complete a survey which determines a score for their internalized bias from 0-100. Without knowing the internalized bias score, patients are asked to rank the subsequent care they receive from the nurse as poor, fair, good or exemplary. In this study what type of variable is your independent variable a. Continuous. This is data which has an infinite number of potential values, and the value you measure falls somewhere on the continuum containing in between variables. 3. Researchers study the impact of internalized bias on patient care. Nurses complete a survey which determines a score for their internalized bias from 0-100. Without knowing the internalized bias score, patients are asked to rank the subsequent care they receive from the nurse as poor, fair, good or exemplary. In this study what type of variable is your dependent variable? a. Ordinal. Ordinal data must be exhaustive and exclusive, just like nominal data, but the answers are also rank ordered. With each rank ordered data, each observation/category is higher or lower, but you do not know the level of difference b/w observations/categories. 4. Researchers examined the relationship between interpersonal violence and health in college age women. They include an independent variable of exposure to violence from an intimate partner, other personal violence or both. The researchers wish to present a table showing the frequencies for each of these exposures. What might you suggest to best display the data? a. Bar chart. A bar chart is set up to display nominal and categorical data. It can display one or more variables. A typical bar chart has the response for the nominal variables on the horizontal axis and place the frequencies of the responses on the vertical axis. Bar charts are typically used for nominal and categorical data with spaces b/w the bars because each answer is distinct and in no particular order. 5. You are asked to rank the quality of your nurse manager’s interpersonal interactions with colleagues and patients on a Likert scale of 1-7. You know this means the data can be analyzed at what level. a. Ordinal level. Ordinal data must be exhaustive and exclusive, just like nominal data, but the answers are also rank ordered. With each rank ordered data, each observation/category is higher or lower, but you do not know the level of difference b/w observations/categories. Some researchers consider Likert scales as interval even though technically it is ordinal. "In general many analysts believe that treating them as interval measures results in too few errors to warrant using less powerful statistical procedures" (Polit and Beck, 2017, p. 358). This study source was downloaded by from CourseH on :19:32 GMT -05:00 6. You are asked to answer a question about the quality of your nurse manager’s interpersonal interactions with colleagues and patients as part of her annual evaluation. The options are poor, fair, strong. You know this means: a. The variable is at the ordinal level. Ordinal data must be exhaustive and exclusive, just like nominal data, but the answers are also rank ordered. With each rank ordered data, each observation/category is higher or lower, but you do not know the level of difference b/w observations/categories. 7. Patients on your unit complete a functional mobility test. The test determines how many seconds it takes to walk 20 feet unassisted. Your patient’s speed is reported as a Z score of 2.3. You would expect your patient to walk 20 feet unassisted: a. Faster than the average patient on the unit. Since the z score is higher you would anticipate that the patient is faster on the unit. The z score is a measure that indicates how many standard deviations a value is from the mean value. Since this z score is positive it is above the mean. 8. You have collected data about the fasting blood glucose (FBG) level of participants in your study. You are delighted to find that the variable is normally distributed. If the mean FBG is 82 and the standard deviation is 2.8 in what range would you expect to find the FBG of 68% of your study participants? a. 79.2-84.8. Since you know that one standard deviation contains 68% of the sample, you would subtract one standard deviation from 82 giving you 79.2 and add the standard deviation giving you 84.8. 9. You have collected data about the post void residuals (PVR) of participants in your study. The mean PVR is 120 mls. Because you have some outliers noted in your study you also report a median PVR which is 138 mls. Based on this data you know: a. The variable is not normally distributed. When a variable is normally distributed, the mean, mode and median are all the same with a bell shaped distribution curve. 10. Researchers examined the relationship between interpersonal violence and health in college age women. The researchers administered a psychological distress questionnaire which produced a score on a scale of 0-12. What would be an appropriate measure of central tendency to consider for this variable? a. Any of these measures of central tendency would be appropriate. Measures of central tendency include the mean, median and mode. 11. A researcher collects demographic data on the marital status of the study subjects. The variable is measured as married/not married. What would be the most appropriate measure of central tendency? a. Mode. The mode is the most frequently occurring value or cat
