PSYC 3002
Introduction to Basic Statistics
Final Assessment (Qns & Ans)
2025
General Instructions
1. Read All Questions Carefully: Make sure you understand each question before
ANSing.
2. Time Management: You have a specific amount of time to complete the exam.
Keep an eye on the clock and pace yourself.
3. Allowed Materials: Only use materials that are explicitly allowed. Unauthorized
materials can lead to disqualification.
4. ANS Format: Follow the required format for your ANSs. For example, multiple-
choice questions might need you to select the best ANS, while essay questions
require detailed responses.
5. Academic Integrity: Adhere to the university's honor code. Any form of cheating or
plagiarism is strictly prohibited.
6. Technical Requirements: Ensure your computer and internet connection are
stable. For online exams, you might need a webcam and microphone for proctoring

,1. What is the primary purpose of inferential statistics in
psychological research?
a) To summarize data
b) To make predictions about a population based on sample data
c) To test hypotheses
d) To describe the characteristics of variables
Correct ANS: b
Rationale: Inferential statistics aims to draw conclusions and
make predictions about a population based on data collected from
a sample.
2. Which of the following is an example of a non-parametric
test?
a) t-test
b) ANOVA
c) Mann-Whitney U test
d) Linear regression
Correct ANS: c

used when the assumptions of other tests, like normality, are not
met.

, 3. In a normal distribution, what percentage of the data falls
within one standard deviation of the mean?
a) 50%
b) 68%
c) 95%
d) 99%
Correct ANS: b
Rationale: Approximately 68% of the data in a normal
distribution lies within one standard deviation of the mean.
4. Which measure of central tendency is most influenced by
extreme values?
a) Mean
b) Median
c) Mode
d) Range
Correct ANS: a
Rationale: The mean is sensitive to extreme scores, as it takes
all values into account, while the median and mode are not.
