Measurement: Nominal, 1
THE QUESTIONS ARE IN BOLD FOLLOWED BY ANSWERS.
1. IN TABLE 1, IDENTIFY THE LEVEL OF MEASUREMENT FOR THE CURRENT
THERAPY VARIABLE. PROVIDE A RATIONALE FOR YOUR ANSWER.
ANSWER: THE CURRENT THERAPY VARIABLE WAS MEASURED AT THE
NOMINAL LEVEL. THESE DRUG CATEGORIES WERE PROBABLY DEVELOPED TO
BE EXHAUSTIVE FOR THIS STUDY AND INCLUDED THE CATEGORIES OF DRUGS
THE SUBJECTS WERE RECEIVING. HOWEVER, THE CATEGORIES ARE NOT
EXCLUSIVE, SINCE PATIENTS ARE USUALLY ON MORE THAN ONE CATEGORY
OF THESE DRUGS TO MANAGE THEIR HEALTH PROBLEMS. THE CURRENT
THERAPIES ARE NOT MEASURED AT THE ORDINAL LEVEL BECAUSE THEY
CANNOT BE RANK ORDERED, SINCE NO DRUG CATEGORY CAN BE CONSIDERED
MORE OR LESS BENEFICIAL THAN ANOTHER DRUG CATEGORY (SEE FIGURE 1-1;
GROVE & GRAY, 2019).
2. WHAT IS THE MODE FOR THE CURRENT THERAPY VARIABLE IN THIS
STUDY? PROVIDE A RATIONALE FOR YOUR ANSWER.
ANSWER: THE MODE FOR CURRENT THERAPY WAS Β BLOCKER. A TOTAL OF 100
(94%) OF THE CARDIAC PATIENTS WERE RECEIVING THIS CATEGORY OF DRUG,
WHICH WAS THE MOST COMMON PRESCRIBED DRUG FOR THIS SAMPLE.
3. WHAT STATISTICS WERE CONDUCTED TO DESCRIBE THE BMI OF THE CARDIAC
PATIENTS IN THIS SAMPLE? DISCUSS WHETHER THESE ANALYSIS
TECHNIQUES WERE APPROPRIATE OR INAPPROPRIATE.
ANSWER: BMI WAS DESCRIBED WITH A MEAN AND STANDARD DEVIATION (SD). BMI
MEASUREMENT RESULTED IN RATIO-LEVEL DATA WITH CONTINUOUS VALUES
AND AN ABSOLUTE ZERO (STONE & FRAZIER, 2017). RATIO- LEVEL DATA SHOULD
BE ANALYZED WITH PARAMETRIC STATISTICS SUCH AS THE MEAN AND SD (GROVE
& GRAY, 2017; KNAPP, 2017).
4. RESEARCHERS USED THE FOLLOWING ITEM TO MEASURE REGISTERED
NURSES’ (RNS) INCOME IN A STUDY: WHAT CATEGORY IDENTIFIES YOUR
CURRENT INCOME AS AN RN?
a. LESS THAN $50,000
b. $50,000 TO 59,999
c. $60,000 TO 69,999
,d. $70,000 TO 80,000
e. $80,000 OR GREATER
WHAT LEVEL OF MEASUREMENT IS THIS INCOME VARIABLE? DOES THE
INCOME VARIABLE FOLLOW THE RULES OUTLINED IN FIGURE 1-1? PROVIDE
A RATIONALE FOR YOUR ANSWER.
, ANSWER: IN THIS EXAMPLE, THE INCOME VARIABLE IS MEASURED AT THE
ORDINAL LEVEL. THE INCOME CATEGO- RIES ARE EXHAUSTIVE, RANGING FROM
LESS THAN $50,000 TO GREATER THAN $80,000. THE TWO OPEN-ENDED
