Q. 1 Statistics
Difficulty: Easy (1 Mark)
For a moderately skewed unimodal frequency distribution, what is Karl Pearson's empirical relationship between the Mean, Median, and Mode?
A
Mode = 3 Median - 2 Mean
โœ“ Correct
B
Mean = 3 Mode - 2 Median
C
Median = 3 Mean - 2 Mode
D
Mode = 2 Median - 3 Mean
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
Karl Pearson observed that for moderately asymmetrical unimodal frequency curves, the distance between the mean and mode is approximately three times the distance between the mean and median: (Mean - Mode) โ‰ˆ 3(Mean - Median), which rearranges to Mode = 3 Median - 2 Mean.
Q. 2 Statistics
Difficulty: Easy (1 Mark)
Which measure of central tendency is most severely distorted and influenced by extreme outlier values in a dataset?
A
Arithmetic Mean
โœ“ Correct
B
Median
C
Mode
D
Interquartile Range
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The arithmetic mean uses every numerical value in its calculation ($\sum x / n$), making it highly sensitive to extreme high or low outliers. The median and mode are resistant/robust measures of location.
Q. 3 Statistics
Difficulty: Medium (1 Mark)
When calculating the average rate of speed, velocity, or price-per-unit ratios, which mathematical average is theoretically the most appropriate measure of central tendency?
A
Harmonic Mean
โœ“ Correct
B
Arithmetic Mean
C
Median
D
Mode
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The harmonic mean ($H = n / \sum (1/x_i)$) is the reciprocal of the arithmetic mean of reciprocals. It is mathematically the correct average for rates, ratios, speeds over equal distances, and prices per unit.
Q. 4 Statistics
Difficulty: Easy (1 Mark)
For calculating the average annual growth rate of population, financial compound interest, or index numbers, which average is statistically optimal?
A
Geometric Mean
โœ“ Correct
B
Arithmetic Mean
C
Harmonic Mean
D
Mode
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The geometric mean ($G = (\prod x_i)^{1/n}$) is mathematically designed for averaging percentages, percentage changes, ratios, compounding financial interest, and multi-year demographic growth rates.
Q. 5 Statistics
Difficulty: Medium (1 Mark)
For any set of positive, distinct real numbers ($x_i > 0$), what is the universal mathematical inequality relationship between the Arithmetic Mean (AM), Geometric Mean (GM), and Harmonic Mean (HM)?
A
AM > GM > HM
โœ“ Correct
B
HM > GM > AM
C
GM > AM > HM
D
AM = GM > HM
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The classical AM-GM-HM inequality states that for positive, non-identical numbers, the Arithmetic Mean is strictly greater than the Geometric Mean, which in turn is strictly greater than the Harmonic Mean: $AM > GM > HM$. They are equal only if all values are identical.
Q. 6 Statistics
Difficulty: Easy (1 Mark)
The algebraic sum of the deviations of a set of observations from their arithmetic mean ($\sum (x_i - \bar{x})$) is ALWAYS equal to:
A
Zero (0)
โœ“ Correct
B
One (1)
C
The variance
D
The standard error
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
A fundamental mathematical property of the arithmetic mean is that the sum of positive and negative deviations about the mean cancels out exactly: $\sum (x_i - \bar{x}) = \sum x_i - n\bar{x} = n\bar{x} - n\bar{x} = 0$.
Q. 7 Statistics
Difficulty: Medium (1 Mark)
The sum of squared deviations of a set of values ($\sum (x_i - A)^2$) is minimized when $A$ is chosen as the:
A
Arithmetic Mean
โœ“ Correct
B
Median
C
Mode
D
Geometric Mean
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
By differential calculus, $\sum (x_i - A)^2$ attains its global absolute minimum when $A = \bar{x}$ (the arithmetic mean). Conversely, the sum of absolute deviations $\sum |x_i - A|$ is minimized when $A$ is the median.
Q. 8 Statistics
Difficulty: Easy (1 Mark)
In an ogive (cumulative frequency curve), the value on the horizontal axis corresponding to the intersection point of the 'less than' ogive and 'more than' ogive gives the:
A
Median
โœ“ Correct
B
Arithmetic Mean
C
Mode
D
Variance
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The intersection of the 'less than' cumulative frequency curve ($N/2$ from below) and the 'more than' cumulative frequency curve ($N/2$ from above) occurs precisely at the 50th percentile, which defines the Median.
Q. 9 Statistics
Difficulty: Easy (1 Mark)
What relative measure of dispersion expresses the standard deviation as a percentage of the arithmetic mean to compare variability between datasets with different units of measurement?
A
Coefficient of Variation (CV)
โœ“ Correct
B
Variance
C
Standard Error
D
Range
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The Coefficient of Variation ($CV = (s / \bar{x}) \times 100\%$) is a dimensionless relative measure of dispersion introduced by Karl Pearson, allowing direct comparison of risk or variability across datasets with different units or disparate means.
Q. 10 Statistics
Difficulty: Easy (1 Mark)
If every single observation in a dataset is multiplied by a constant $c = 5$, how does the standard deviation of the transformed dataset change?
A
It is multiplied by 5
โœ“ Correct
B
It is multiplied by 25
C
It remains unchanged
D
It increases by 5 units
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
Multiplying data values by a constant $c$ scales the standard deviation by $|c|$ (so $s_{new} = 5 \times s_{old}$), while the variance scales by $c^2$ (so $s^2_{new} = 25 \times s^2_{old}$). Adding a constant changes neither standard deviation nor variance.
Q. 11 Statistics
Difficulty: Easy (1 Mark)
If every observation in a dataset is increased by adding a constant $k = 10$, what happens to the standard deviation and the variance?
A
Both standard deviation and variance remain completely unchanged
โœ“ Correct
B
Standard deviation increases by 10
C
Variance increases by 100
D
Standard deviation is multiplied by 10
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
Measures of dispersion (range, IQR, mean deviation, variance, standard deviation) are independent of change of origin. Adding or subtracting a constant shifts all points equally without altering their spread relative to each other.
Q. 12 Statistics
Difficulty: Easy (1 Mark)
The Interquartile Range (IQR) is mathematically defined as the difference between which two percentiles?
A
Third Quartile ($Q_3$ / 75th percentile) and First Quartile ($Q_1$ / 25th percentile)
โœ“ Correct
B
90th percentile and 10th percentile
C
Maximum and Minimum value
D
Mean and Median
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The Interquartile Range ($IQR = Q_3 - Q_1$) spans the central 50% of ordered observations, serving as an outlier-resistant measure of statistical spread.
Q. 13 Statistics
Difficulty: Medium (1 Mark)
In John Tukey's standard Box-and-Whisker plot, an observation is classified as an 'outlier' if it lies beyond:
A
$Q_1 - 1.5 \times IQR$ or $Q_3 + 1.5 \times IQR$
โœ“ Correct
B
$Mean \pm 1.0 \times SD$
C
$Q_1 - 0.5 \times IQR$ or $Q_3 + 0.5 \times IQR$
D
Beyond the 95th percentile only
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
Tukey established the 'inner fences' of a boxplot at $[Q_1 - 1.5 \cdot IQR, Q_3 + 1.5 \cdot IQR]$. Data points falling outside these fences are plotted individually as suspected outliers.
Q. 14 Statistics
Difficulty: Easy (1 Mark)
What is the value of the first central moment ($\mu_1$) about the arithmetic mean for any probability distribution?
A
Exactly 0
โœ“ Correct
B
Exactly 1
C
The variance
D
The standard deviation
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The $r$-th central moment is defined as $\mu_r = E[(X - \mu)^r]$. For $r = 1$, $\mu_1 = E[X - \mu] = E[X] - \mu = \mu - \mu = 0$ for every valid distribution.
Q. 15 Statistics
Difficulty: Easy (1 Mark)
The second central moment about the mean ($\mu_2 = E[(X - \mu)^2]$) represents which fundamental statistical parameter?
A
Variance
โœ“ Correct
B
Standard error
C
Skewness
D
Kurtosis
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
By definition, the second central moment $\mu_2$ is the variance ($\sigma^2$), measuring dispersion of observations around the population mean.
Q. 16 Statistics
Difficulty: Medium (1 Mark)
Karl Pearson's moment coefficient of skewness ($\beta_1$) is calculated using the second and third central moments as:
A
$\beta_1 = \mu_3^2 / \mu_2^3$
โœ“ Correct
B
$\beta_1 = \mu_3 / \mu_2$
C
$\beta_1 = \mu_4 / \mu_2^2$
D
$\beta_1 = \mu_2^3 / \mu_3^2$
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
Pearson defined $\beta_1 = \mu_3^2 / \mu_2^3$. The standardized skewness coefficient is $\gamma_1 = \sqrt{\beta_1} = \mu_3 / \sigma^3$. For a symmetric distribution, $\mu_3 = 0$ and $\beta_1 = 0$.
Q. 17 Statistics
Difficulty: Easy (1 Mark)
A continuous frequency curve has a long tail stretching to the right side (positive values). What is the relative order of the three measures of central location?
A
Mean > Median > Mode
โœ“ Correct
B
Mode > Median > Mean
C
Median > Mean > Mode
D
Mean = Median = Mode
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
In a positively (right) skewed distribution, extreme high values pull the mean farthest into the right tail, resulting in: $\text{Mean} > \text{Median} > \text{Mode}$. In a negatively (left) skewed distribution: $\text{Mode} > \text{Median} > \text{Mean}$.
Q. 18 Statistics
Difficulty: Easy (1 Mark)
Karl Pearson's coefficient of kurtosis is defined as $\beta_2 = \mu_4 / \mu_2^2$. What is the value of $\beta_2$ for a perfectly normal (mesokurtic) distribution?
A
3.0 (or excess kurtosis $\gamma_2 = \beta_2 - 3 = 0$)
โœ“ Correct
B
0.0
C
1.0
D
0.5
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
For any Gaussian (normal) distribution, the ratio of the fourth central moment to the square of the second central moment is exactly $\beta_2 = 3$. Excess kurtosis is defined as $\gamma_2 = \beta_2 - 3 = 0$.
Q. 19 Statistics
Difficulty: Easy (1 Mark)
A distribution that is more peaked around its center than a normal distribution and has fatter, heavier tails (with $\beta_2 > 3$) is classified as:
A
Leptokurtic
โœ“ Correct
B
Platykurtic
C
Mesokurtic
D
Symmetrical
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
Distributions with $\beta_2 > 3$ (excess kurtosis $> 0$) are termed 'leptokurtic' (sharp peak, heavy tails). Distributions with $\beta_2 < 3$ are 'platykurtic' (flatter peak, lighter tails), and $\beta_2 = 3$ is 'mesokurtic'.
Q. 20 Statistics
Difficulty: Easy (1 Mark)
Two events $A$ and $B$ are said to be 'mutually exclusive' (disjoint) if and only if:
A
They cannot occur simultaneously ($P(A \cap B) = 0$)
โœ“ Correct
B
$P(A \cap B) = P(A) \times P(B)$
C
$P(A) + P(B) = 1$
D
$P(A|B) = P(A)$
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
Mutually exclusive events have an empty intersection ($A \cap B = \emptyset$). Hence, the probability that both occur simultaneously is zero: $P(A \cap B) = 0$.
Q. 21 Statistics
Difficulty: Easy (1 Mark)
Two events $A$ and $B$ are statistically 'independent' if and only if:
A
$P(A \cap B) = P(A) \times P(B)$
โœ“ Correct
B
$P(A \cap B) = 0$
C
$P(A \cup B) = P(A) + P(B)$
D
$P(A) = P(B)$
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
By definition, events $A$ and $B$ are statistically independent when the occurrence of one does not affect the probability of the other, meaning $P(A|B) = P(A)$, which yields the multiplicative rule: $P(A \cap B) = P(A) \times P(B)$.
Q. 22 Statistics
Difficulty: Easy (1 Mark)
If two fair six-sided dice are rolled simultaneously, what is the probability of obtaining a sum equal to 7?
A
6 / 36 (1 / 6)
โœ“ Correct
B
1 / 36
C
7 / 36
D
1 / 12
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
There are $6 \times 6 = 36$ equally likely outcomes. The outcomes summing to 7 are: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1)โ€”totaling 6 favorable outcomes. Thus, $P(\text{Sum} = 7) = 6/36 = 1/6$.
Q. 23 Statistics
Difficulty: Medium (1 Mark)
Bayes' Theorem provides a mathematical framework for calculating:
A
Posterior probability given prior probabilities and conditional likelihoods
โœ“ Correct
B
The arithmetic mean of a sample
C
The exact range of a continuous variable
D
The degrees of freedom in an ANOVA table
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
Bayes' Theorem ($P(A_i|B) = \frac{P(B|A_i)P(A_i)}{\sum P(B|A_j)P(A_j)}$) updates the prior probability of an event $A_i$ upon observing new empirical evidence $B$ to calculate the revised posterior probability.
Q. 24 Statistics
Difficulty: Easy (1 Mark)
For a discrete random variable $X$ with probability mass function $P(X = x)$, what two mathematical conditions must be satisfied?
A
$P(X = x) \ge 0$ for all $x$, and $\sum P(X = x) = 1$
โœ“ Correct
B
$P(X = x) \le 0$, and $\sum P(X = x) = 0$
C
$P(X = x) > 1$, and $\sum P(X = x) = 100$
D
$\sum P(X = x) = \infty$
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
The axioms of probability mandate that every individual probability mass must be non-negative ($0 \le P(X=x) \le 1$), and the sum of probabilities across the entire sample space must equal exactly 1.
Q. 25 Statistics
Difficulty: Medium (1 Mark)
For a continuous random variable $X$ with probability density function $f(x)$, what is the probability that $X$ takes on any single exact point value $c$ ($P(X = c)$)?
A
Exactly 0
โœ“ Correct
B
Exactly 1
C
$f(c)$
D
$0.5$
๐Ÿ’ก Step-by-Step Explanation & Concept Rationale
For continuous random variables, probabilities correspond to areas under the density curve: $P(a \le X \le b) = \int_a^b f(x) dx$. Because the area over a single dimensionless point is zero, $P(X = c) = \int_c^c f(x) dx = 0$.
