Table 1: Summary of Central Tendency Measures

Measure	Formula	Interpretation
Mean	Sum / Number of values	Average value
Median	Middle value when sorted	Midpoint of the data
Mode	Most frequently occurring value	Common value

Table 2: Comparison of Discrete Probability Distributions

Distribution	PMF	Characteristics
Binomial	P(X=x) = (n choose x) * p^x * (1-p)^(n-x)	Number of successes in n independent trials
Poisson	P(X=x) = (e^-λ * λ^x) / x!	Number of events occurring over a fixed time or interval
Hypergeometric	P(X=x) = (n choose r) * (N-n choose k-r) / (N choose k)	Number of successes drawn without replacement from a finite population

Table 3: Comparison of Continuous Probability Distributions

Distribution	PDF	Characteristics
Normal	f(x) = (1 / √(2πσ^2)) * e^(-(x-μ)^2 / (2σ^2))	Symmetric, bell-shaped curve
Exponential	f(x) = λ * e^(-λx)	Constant probability per unit time
Uniform	f(x) = 1 / (b-a)	Equally likely to occur within a specified interval

Table 4: Hypothesis Testing Procedure

Step	Action
1	Formulate null and alternative hypotheses
2	Select an appropriate test statistic
3	Collect data and calculate the test statistic
4	Determine the p-value
5	Make a decision: Reject null hypothesis (p-value < α) or fail to reject (p-value > α)
