Module 1: Data Types and Categorization
1. What type of data is represented by the heart rate (in beats per minute) of a
patient?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
D) Ratio (It has a true zero point, meaning 0 bpm indicates the absence
of a heartbeat.)
2. The classification of blood type as A+, B-, O+, etc., is an example of what
level of measurement?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
A) Nominal (Categories with no inherent order.)
3. A patient's pain level rated on a scale of 1 (No pain) to 10 (Worst pain) is
what type of data?
A) Nominal
B) Ordinal
C) Interval
D) Ratio
B) Ordinal (The order matters, but the differences between values are
not necessarily equal.)
,4. Body temperature in degrees Fahrenheit is considered:
A) Nominal
B) Ordinal
C) Interval
D) Ratio
C) Interval (0 degrees does not mean "no temperature"; it is an arbitrary
point.)
5. Which of the following is a qualitative variable?
A) Patient's age
B) Number of medications
C) Type of surgical procedure
D) Length of hospital stay
C) Type of surgical procedure (It describes a category or quality.)
6. The number of readmissions to a hospital within 30 days is an example of:
A) Continuous data
B) Discrete data
C) Ordinal data
D) Interval data
B) Discrete data (You can count it in whole numbers.)
7. A researcher records the weight of patients in kilograms. This is an example
of:
A) Continuous data
B) Discrete data
C) Nominal data
D) Ordinal data
A) Continuous data (Weight can be measured and broken down into
fractions of a unit.)
8. Which of the following is a discrete variable?
A) Height
B) Blood Pressure
C) Number of children in a family
, D) Time to run a mile
C) Number of children in a family (You can't have 2.5 children.)
Module 2: Descriptive Statistics & Central Tendency
9. What is the median of the following dataset: 5, 2, 8, 1, 9?
A) 5
B) 2
C) 8
D) 1
A) 5 (Ordered: 1, 2, 5, 8, 9. The middle value is 5.)
10.In a positively skewed distribution, where is the mean in relation to the
median?
A) Mean is less than the median
B) Mean is equal to the median
C) Mean is greater than the median
D) There is no relationship
C) Mean is greater than the median (The tail on the right pulls the
mean higher.)
11.The most frequently occurring value in a dataset is called the:
A) Mean
B) Median
C) Mode
D) Range
C) Mode
12.Calculate the range for the following data: 10, 15, 12, 18, 22, 25, 30
A) 10
B) 15
C) 20
D) 30
C) 20 (Range = Max - Min = 30 - 10 = 20)
13.A dataset has two modes. This distribution is called:
A) Unimodal
