1. Which of the following measures of central tendency is most affected by extreme values?
A) Mean
B) Median
C) Mode
D) Range
Answer: A) Mean
PAGE 1
,Explanation: The mean is sensitive to extreme values (outliers) because it involves summing all values and
dividing by the number of observations. In contrast, the median and mode are less affected by outliers.
2. What does the standard deviation measure in a data set?
A) The difference between the highest and lowest values
B) The average value
C) The spread of the data around the mean
D) The most frequently occurring value
Answer: C) The spread of the data around the mean
Explanation: Standard deviation quantifies the amount of variation or dispersion in a set of data values,
indicating how much the values deviate from the mean.
3. If two events A and B are independent, then P(A and B) is equal to:
A) P(A) + P(B)
B) P(A) × P(B)
C) P(A) / P(B)
D) P(A) - P(B)
Answer: B) P(A) × P(B)
Explanation: For independent events, the probability of both occurring is the product of their individual
probabilities.
4. In a normal distribution, approximately what percentage of data lies within one standard deviation of
the mean?
A) 50%
B) 68%
C) 95%
D) 99.7%
Answer: B) 68%
Explanation: According to the Empirical Rule, about 68% of data in a normal distribution falls within one
standard deviation of the mean.

, 5. What type of sampling involves dividing the population into subgroups and randomly selecting
samples from each subgroup?
A) Simple random sampling
B) Systematic sampling
C) Stratified sampling
D) Cluster sampling
Answer: C) Stratified sampling
Explanation: Stratified sampling ensures representation from each subgroup (strata) by dividing the population
and randomly selecting samples from each stratum.
6. Which measure of variability is the difference between the highest and lowest values in a data set?
A) Variance
B) Standard deviation
C) Range
D) Interquartile range
Answer: C) Range
Explanation: The range is calculated by subtracting the smallest value from the largest value in a data set.
7. What is the null hypothesis in hypothesis testing?
A) The hypothesis that there is an effect or difference
B) The hypothesis that there is no effect or difference
C) The hypothesis that the alternative is true
D) The hypothesis that the sample is representative
Answer: B) The hypothesis that there is no effect or difference
Explanation: The null hypothesis typically states that there is no effect or no difference, and it is tested against
the alternative hypothesis.
8. In regression analysis, what does the R-squared value represent?
A) The slope of the regression line
B) The intercept of the regression line
C) The proportion of variance in the dependent variable explained by the independent variable(s)
D) The correlation between two variables
