,1. Question: Which of the following units is used to
measure mass in the metric system?
- a) Liter
- b) Gram
- c) Meter
- d) Second
- Answer: b) Gram
- Rationale: Grams are the unit used to measure mass
in the metric system, while liters measure volume, meters
measure length, and seconds measure time.
2. Question: If a dataset has a mean of 50 and a
standard deviation of 5, what is the z-score of a data point
that is 45?
- a) -1
- b) 0
- c) 1
- d) 2
- Answer: a) -1
- Rationale: The z-score is calculated as \( (X - \mu) /
\sigma \). Here \( (45 - 50) / 5 = -1 \).
3. Question: Which of the following best describes the
median?
- a) The most frequently occurring value
- b) The average of all data points
- c) The middle value when data is ordered
- d) The range of the dataset
- Answer: c) The middle value when data is ordered
- Rationale: The median is the middle value in an
ordered dataset. It separates the higher half from the lower
half.

, 4. Question: What is the interquartile range (IQR) of the
dataset: 4, 7, 9, 15, 21?
- a) 5
- b) 7
- c) 11
- d) 8
- Answer: c) 11
- Rationale: The IQR is Q3 (15) - Q1 (4), resulting in 11.
5. Question: Which of the following would NOT be used
to describe the shape of a distribution?
- a) Symmetry
- b) Modality
- c) Z-score
- d) Kurtosis
- Answer: c) Z-score
- Rationale: Z-scores are used for standardization, not
to describe the shape of a distribution.
### Multiple-Select Questions
6. Question: Select all the following measures that are
classified as measures of central tendency.
- a) Mean
- b) Standard Deviation
- c) Median
- d) Variance
- e) Mode
- Answers: a) Mean, c) Median, e) Mode
- Rationale: Mean, median, and mode are measures of
central tendency, whereas standard deviation and variance
are measures of variability.
