The Correct Answer and Explanation is :
The variable “type of medicine taken for high blood pressure” is qualitative. This is because it describes categories or types of medications, such as ACE inhibitors, beta-blockers, diuretics, or calcium channel blockers. These categories are not numerical and do not involve counting or measuring quantities. Instead, they represent different categories of medication used to treat high blood pressure, which is a clear indicator of a qualitative variable.
Explanation:
A qualitative variable, also known as a categorical variable, refers to variables that express categories or labels that do not have a specific numerical value. For instance, the type of medicine for high blood pressure can be classified into groups such as “ACE inhibitors” or “diuretics,” and these categories do not have inherent numerical significance. While there are numerical identifiers or codes for these categories, the essence of the variable is categorical.
On the other hand, quantitative variables are those that can be counted or measured and are represented by numbers. They are divided into two subtypes:
- Quantitative-discrete variables: These variables represent countable quantities, such as the number of doses taken per day.
- Quantitative-continuous variables: These variables represent measurements that can take any value within a range, such as the exact dosage of medication (e.g., 50 mg or 100 mg).
In this case, since the variable is concerned with the type of medicine, which is a categorical distinction and does not involve numerical counting or measurement, it is classified as qualitative.
