Question:
Which of the following is an example of discrete data?
Which of the following is an example of discrete data?
Show Hint
Counts (number of teeth, number of patients, number of lesions) → Discrete data
Measurements (temperature, weight, hemoglobin) → Continuous data.
Measurements (temperature, weight, hemoglobin) → Continuous data.

- Hemoglobin level in blood
- Age in years
- Temperature in degrees Fahrenheit
- DMFT total score
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding Discrete Data.
Discrete data consists of countable values that can only take specific separate numbersUsually, these are whole numbers and represent counts rather than measurements
Step 2: Analyzing the Options.
Hemoglobin level in blood is a continuous variable because it can take fractional values
Age in years, though sometimes recorded in whole numbers, is fundamentally continuous because it can be measured in fractions of years
Temperature in degrees Fahrenheit is also continuous as it can take decimal values
DMFT (Decayed, Missing, Filled Teeth) total score is a count of teeth affectedIt can only take whole number values and therefore represents discrete data
Step 3: Conclusion.
Since DMFT total score is countable and expressed in whole numbers, it is an example of discrete data
