The process of synthesizing the best scientific evidence with clinical expertise and patient preferences to make clinical decisions is known as:
A nurse records a patient's marital status as "Single," "Married," or "Divorced." This type of data is measured on which scale?
What is the arithmetic average of a set of numerical data called?
A patient satisfaction survey asks patients to rate their care as "Excellent," "Good," "Fair," or "Poor." This is an example of which scale of measurement?
A nurse is analyzing the following patient temperature readings: 37.0, 37.5, 38.0, 38.0, 39.0. Which value represents the mode?
What does a small standard deviation indicate about a set of data?
Which measure of central tendency is most affected by a single extremely high or low value (an outlier) in a dataset?
A table that lists each value in a dataset and the number of times it occurs is called a:
A nurse measures a patient's height in centimeters and weight in kilograms. These measurements are on a ratio scale because they:
A staff nurse reads a research article on a new method for preventing pressure ulcers and implements it for their patients. This is a direct example of:
What is the median of the following set of patient lengths of stay (in days): [4, 2, 8, 5, 10]?
Temperature measured in Fahrenheit or Celsius is an example of which scale of measurement?
The primary goal of utilizing nursing research findings in clinical practice is to:
The standard deviation is a measure of:
Which of the following is an essential role for a staff nurse in promoting EBP on a hospital unit?
What is the middle value in a dataset that has been ranked from lowest to highest?
To calculate a meaningful mean (average), what is the minimum level of measurement required for the data?
Descriptive statistics are used to:
A study reports that the mean age of patients is 65 with a standard deviation of 15 years. This indicates:
Which of the following represents the most frequent score in a dataset?
When data is presented in a normal distribution (a "bell curve"), the mean, median, and mode are:
A staff nurse who understands basic statistics is better able to:
A nurse records a patient's pulse rate (beats per minute). This is an example of which scale of measurement?
The PICO format is a tool used in EBP to help a nurse:
If a study on patient recovery times shows a large standard deviation, it means that:
