Consider the following variables which pertain to an observational study on diabetes: (1) Blood type (A, B, AB, or O). (2) Subject's weight (kg). (3) Hypoglycemia episode experienced by subject (Yes or No). (4) Type of diabetes (Type 1 or Type II). (5) Blood sugar level (mg/dl). (6) Length of visit (in days). (7) Number of hours spent on exercise per week. The quantitative variables in this list are Select one: O a. (2), (4), (5), (6), and (7). o b. (1), (3), and (4) O C. (1), (2), (5), and (6). o d. (1), (2), (5), and (7) O e. (2), (5), (6), and (7). .

Answer 1

Qualitative variables are variables those take a name or a label as its value whereas quantitative variables take numeric value and they are measurable.

Now let us look at the variables given in the question

Blood group - This is a qualitative variable as it takes the labels A, B, AB, O etc as its value

Subjects Weight - This is a quantitative variable as the weight take a measurable numeric value

Hypoglycemia episode experienced by subject - This takes the value " yes" or "no" which is not a numeric. Thus the variable is qualitative

Type of diabetes- Type 1, Type 2 - This is qualitative as they  are two categories which diabetic patients are classified into.

Blood sugar level - This is quantitative as a numeric values are assigned to this

Length of visit - quantitative as it takes the number of days ( which are numeric) as values

Number of hours spent on exercise every week- Quantitative variable as the hours are measured as a numeric value.

Therefore the answer is option e - 2,5,6 &7
