Chapter 3 Activity Name After your efficient completion of inoculationg the apartment building (you saved everyone!), you’ve gained a reputation as a nurse well versed in statistics. Because of this, you’ve been asked to complete another task. Mission: A survey was given to patients seen during the epidemic. In order for the data to be analyzed, the levels of measurement for each of the survey questions must be identified. Use the sample survey below, and identify the levels of measurement (nominal, ordinal, interval, and ratio): Dangerous Epidemic Health Survey – SAMPLE Enter your level of measurements below. 1. What is your gender? (Ex. Male/Female) nominal 2. What is your resting heart rate? (Ex. 90 bpm) Ratio 3. What is your height in inches? Ex. 65 inches) Ratio 4. How many cigarettes do you smoke per day? None 1 -5 per day 6 – 10 per day ordinal 11 – 20 per day Over 20 per day 5. How much exercise do you get on an average day? Minimal (no specific exercise or daily routine) nominal . Moderate (e.g. walking) . Vigorous (e.g. jogging, cycling) 6. What is your smoking status? ordinal (Ex. 0 – Nonsmoker, 1 – Smoker) 7. I have 5 portions of fruit and vegetables each day. (Ex. Yes/No) 8. I would rate my overall health as Excellent Good Average Below Average Poor 9. What is the sea level where you live?
Certainly, let’s identify the levels of measurement for each of the survey questions in the “Dangerous Epidemic Health Survey – SAMPLE”
This question represents nominal measurement because gender categories (Male/Female) are categorical and cannot be ranked or quantified.
Resting heart rate is measured on a continuous scale with a meaningful zero point (absence of a heartbeat), making it a ratio measurement.
Height in inches is also a ratio measurement because it has a meaningful zero point (complete absence of height) and can be measured on a continuous scale.
None
1 – 5 per day
6 – 10 per day
Over 20 per day
Ordinal
This question involves ordinal measurement because it presents ordered categories, but the intervals between them are not uniform.
Minimal (no specific exercise or daily routine)
Moderate (e.g., walking)
Vigorous (e.g., jogging, cycling)
Ordinal
Similar to the previous question, it’s ordinal because it ranks exercise intensity without uniform intervals.
Smoking status is ordinal as it represents different categories, but the numbers don’t imply a specific quantity.
This question is nominal because it categorizes individuals as either having or not having a specific behavior (consuming 5 portions of fruits and vegetables).
Excellent
Good
Average
Below Average
Poor
Ordinal
This question asks participants to rank their health on an ordinal scale, but the intervals between categories may not be uniform.
Sea level measurement is interval because it represents an ordered scale without a meaningful zero point (there’s no “absence” of sea level). However, it has consistent intervals between measurements.
These identified levels of measurement help researchers understand the nature of the data collected and guide appropriate statistical analyses and interpretations.
