Data analysis, probability and statistics

Covers discrete and continuous random variables, probability distributions, and statistical inference for sample proportions.

Key Knowledge Detail

discrete random variables: - specification of probability distributions for discrete random variables using graphs, tables and probability mass functions - calculation and interpretation of mean, $\mu$, variance, $\sigma^{2}$, and standard deviation of a discrete random variable and their use - Bernoulli trials and the binomial distribution, $\operatorname{Bi}(n, p)$, as an example of a probability distribution for a discrete random variable - effect of variation in the value(s) of defining parameters on the graph of a given probability mass function for a discrete random variable - calculation of probabilities for specific values of a random variable and intervals defined in terms of a random variable, including conditional probability
