8. Which is NOT a measure of central tendency?
A. Mean
B. Median
C. Mode
D. Standard deviation
Correct Answer: D
,9. The median is best described as:

B. Average of all values
C. Middle value when data is ordered
D. Difference between max and min
Correct Answer: C
10. Which measure is most affected by extreme values?
A. Median
B. Mode
C. Mean
D. Range only
Correct Answer: C
11. Which of the following is a categorical variable?
A. Age
B. Height
C. Blood group
D. Weight
Correct Answer: C

measurements.
12. What type of data is “number of hospital visits in a year”?
A. Continuous
B. Discrete
C. Nominal
D. Ordinal
Correct Answer: B
Rationale: It is a countable whole number, making it discrete data.
, 13. Which is an example of continuous data?
A. Number of children
B. Weight
C. Number of patients
D. Type of disease
Correct Answer: B
Rationale: Weight can take any value within a range, so it is continuous.

A. Ratio
B. Interval
C. Ordinal
D. Nominal
Correct Answer: D
Rationale: Marital status consists of categories without order.
15. Which measure is NOT affected by extreme values?
A. Mean
B. Median

16. The mean is best described as:
A. Middle value
B. Most frequent value
C. Average of all values
D. Difference between highest and lowest
Correct Answer: C
