📈 Part 1: Statistics

1. Measures of Central Tendency

Basic Concepts

📖 Central Tendency Measures:

1. Mean (Average):
   Arithmetic Mean: x̄ = (x₁ + x₂ + ... + xₙ)/n
   Weighted Mean: x̄ = (w₁x₁ + w₂x₂ + ... + wₙxₙ)/(w₁ + w₂ + ... + wₙ)

2. Median:
   Middle value when data is arranged in order
   For odd n: Middle observation
   For even n: Average of two middle observations

3. Mode:
   Most frequently occurring value
   Data can have no mode, one mode, or multiple modes

4. Properties:
   - Mean is affected by extreme values
   - Median is resistant to extreme values
   - Mode is useful for categorical data

Grouped Data Statistics

📊 Grouped Data Methods:

1. Mean for Grouped Data:
   x̄ = (Σ(fᵢ × xᵢ))/Σfᵢ
   where fᵢ = frequency, xᵢ = class midpoint

2. Median for Grouped Data:
   Median = L + [(N/2 - cf)/f] × h
   where L = lower limit of median class
   N = total frequency, cf = cumulative frequency before median class
   f = frequency of median class, h = class width

3. Mode for Grouped Data:
   Mode = L + [(f₁ - f₀)/(2f₁ - f₀ - f₂)] × h
   where L = lower limit of modal class
   f₁ = frequency of modal class
   f₀ = frequency before modal class
   f₂ = frequency after modal class

2. Measures of Dispersion

Basic Dispersion Measures

📖 Dispersion Fundamentals:

1. Range:
   Range = Maximum value - Minimum value
   Simple but sensitive to extreme values

2. Mean Deviation:
   About Mean: MD = (Σ|xᵢ - x̄|)/n
   About Median: MD = (Σ|xᵢ - Median|)/n

3. Variance:
   Population Variance: σ² = (Σ(xᵢ - μ)²)/N
   Sample Variance: s² = (Σ(xᵢ - x̄)²)/(n-1)

4. Standard Deviation:
   σ = √σ² (population), s = √s² (sample)
   Same units as original data

Advanced Measures

   CV = (σ/μ) × 100%
   Useful for comparing variability

2. Quartiles:
   Q₁: First quartile (25th percentile)
   Q₂: Second quartile (median, 50th percentile)
   Q₃: Third quartile (75th percentile)

3. Interquartile Range:

Variance = [(2-6)² + (4-6)² + (6-6)² + (8-6)² + (10-6)²]/5
= [16 + 4 + 0 + 4 + 16]/5 = 40/5 = 8
SD = √8 = 2√2

Example 2 (Range and IQR, 2022):
Q: Find range and IQR of: 5, 8, 12, 15, 19, 22, 28.

IQR = 22 - 8 = 14

Example 3 (Mean Deviation, 2023):
Q: Find mean deviation about mean for: 10, 12, 14, 16, 18.
Solution: Mean = (10+12+14+16+18)/5 = 70/5 = 14
MD = [|10-14| + |12-14| + |14-14| + |16-14| + |18-14|]/5
= [4 + 2 + 0 + 2 + 4]/5 = 12/5 = 2.4

Example 4 (Coefficient of Variation, 2020):
Q: Data A: mean = 50, SD = 10; Data B: mean = 100, SD = 15
   Which has more relative variation?
Solution: CV(A) = (10/50) × 100 = 20%
CV(B) = (15/100) × 100 = 15%
Data A has more relative variation

Example 5 (Grouped Data SD, 2021):

   Class: 0-10, 10-20, 20-30
   Frequency: 3, 4, 3
Solution: x̄ = (3×5 + 4×15 + 3×25)/10 = (15 + 60 + 75)/10 = 150/10 = 15
Variance = [3(5-15)² + 4(15-15)² + 3(25-15)²]/10
= [3(100) + 4(0) + 3(100)]/10 = 600/10 = 60

🎲 Part 2: Probability

1. Basic Probability

Fundamental Concepts

📖 Probability Basics:

1. Sample Space (S):
   Set of all possible outcomes
   Denoted by S or Ω

2. Event:
   Subset of sample space
   Denoted by E, A, B, etc.

3. Probability of Event:
   P(E) = Number of favorable outcomes / Total number of outcomes
   0 ≤ P(E) ≤ 1

4. Axioms of Probability:
   - P(S) = 1 (certain event)
   - P(E) ≥ 0 for any event E
   - P(A ∪ B) = P(A) + P(B) for mutually exclusive events

Basic Probability Rules

🎯 Probability Rules:

1. Complement Rule:
   P(E') = 1 - P(E)
   where E' is complement of E

2. Addition Rule:
   P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

3. Mutually Exclusive Events:
   P(A ∪ B) = P(A) + P(B) if A ∩ B = ∅

4. Exhaustive Events:
   P(A ∪ B) = 1 if A ∪ B = S

Previous Year Questions

💡 Representative Questions:

Example 1 (Basic Probability, 2021):
Q: A die is rolled. Find probability of getting an even number.
Solution: Sample space = {1, 2, 3, 4, 5, 6}
Even numbers = {2, 4, 6}
P(even) = 3/6 = 1/2

Example 2 (Card Probability, 2022):
Q: A card is drawn from standard deck. Find probability of drawing a heart.
Solution: Total cards = 52, Hearts = 13
P(Heart) = 13/52 = 1/4

Example 3 (Complement Rule, 2023):
Q: Probability that it will rain tomorrow is 0.3. Find probability it won't rain.
Solution: P(no rain) = 1 - 0.3 = 0.7

Example 4 (Addition Rule, 2020):
Q: P(A) = 0.4, P(B) = 0.5, P(A ∩ B) = 0.2. Find P(A ∪ B).
Solution: P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
= 0.4 + 0.5 - 0.2 = 0.7

Example 5 (Dice Problem, 2021):
Q: Two dice are rolled. Find probability that sum is 7.
Solution: Total outcomes = 36
Favorable outcomes: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) = 6
P(sum = 7) = 6/36 = 1/6

2. Conditional Probability

Conditional Probability Concepts

📖 Conditional Fundamentals:

1. Definition:
   P(A|B) = P(A ∩ B) / P(B)
   Probability of A given B has occurred

2. Multiplication Rule:
   P(A ∩ B) = P(A) × P(B|A) = P(B) × P(A|B)

3. Independent Events:
   A and B are independent if P(A|B) = P(A)
   Equivalent to P(A ∩ B) = P(A) × P(B)

4. Bayes' Theorem:
   P(A|B) = P(B|A) × P(A) / P(B)
   Used for "reverse" probabilities

Bayes’ Theorem Applications

🎯 Bayes' Theorem Extended Form:

P(Aᵢ|B) = [P(B|Aᵢ) × P(Aᵢ)] / [Σ(P(B|Aⱼ) × P(Aⱼ))]

Where:
- A₁, A₂, ..., Aₙ are mutually exclusive and exhaustive events
- B is the observed event
- We want P(Aᵢ|B) given P(Aᵢ) and P(B|Aᵢ)

Previous Year Questions

💡 Representative Questions:

Example 1 (Conditional Probability, 2021):
Q: P(A) = 0.6, P(B) = 0.4, P(A ∩ B) = 0.3. Find P(A|B).
Solution: P(A|B) = P(A ∩ B) / P(B) = 0.3 / 0.4 = 3/4 = 0.75

Example 2 (Independence Check, 2022):
Q: P(A) = 0.5, P(B) = 0.4, P(A ∩ B) = 0.2. Are A and B independent?
Solution: P(A) × P(B) = 0.5 × 0.4 = 0.2 = P(A ∩ B)
Therefore, A and B are independent ✓

Example 3 (Bayes' Theorem, 2023):
Q: Box A has 2 red, 3 blue balls. Box B has 4 red, 1 blue balls.
   A box is chosen at random (50% each), then a ball is drawn.
   Given that a red ball is drawn, find probability it came from Box A.
Solution: Let A = "Box A chosen", B = "Box B chosen", R = "Red ball drawn"
P(A) = P(B) = 0.5
P(R|A) = 2/5, P(R|B) = 4/5
P(A|R) = P(R|A) × P(A) / [P(R|A) × P(A) + P(R|B) × P(B)]
= (2/5 × 0.5) / [(2/5 × 0.5) + (4/5 × 0.5)]
= (1/5) / [(1/5) + (2/5)] = (1/5) / (3/5) = 1/3

Example 4 (Medical Test, 2020):
Q: Disease affects 1% of population. Test is 95% accurate for diseased
   and 90% accurate for healthy. If test is positive, find probability
   person actually has disease.
Solution: Let D = "has disease", T = "test positive"
P(D) = 0.01, P(D') = 0.99
P(T|D) = 0.95, P(T|D') = 0.10 (false positive)
P(D|T) = P(T|D) × P(D) / [P(T|D) × P(D) + P(T|D') × P(D')]
= (0.95 × 0.01) / [(0.95 × 0.01) + (0.10 × 0.99)]
= 0.0095 / (0.0095 + 0.099) = 0.0095 / 0.1085 ≈ 0.0876

Example 5 (Complex Conditional, 2021):
Q: Two cards drawn without replacement from deck.
   Find probability second card is king given first card is ace.

Solution: E[X] = 1×0.2 + 2×0.5 + 3×0.3 = 0.2 + 1.0 + 0.9 = 2.1
E[X²] = 1²×0.2 + 2²×0.5 + 3²×0.3 = 0.2 + 2.0 + 2.7 = 4.9
Var(X) = E[X²] - (E[X])² = 4.9 - 2.1² = 4.9 - 4.41 = 0.49

Example 3 (Binomial Distribution, 2023):
Q: Coin tossed 5 times. Find probability of exactly 3 heads.
Solution: X ~ B(5, 0.5)

Example 5 (Normal Distribution, 2021):
Q: X ~ N(100, 25). Find P(X > 110).
Solution: Standardize: Z = (110 - 100) / √25 = 10 / 5 = 2
P(X > 110) = P(Z > 2) = 1 - P(Z < 2) = 1 - 0.9772 = 0.0228
