Usually its value is unknown. The field of statistics is the science of learning from data.  Statistics is concerned with scientific methods for ◦ collecting, ◦ organising, ◦ summarising, ◦ presenting and analysing data ◦ as well as deriving valid conclusions and making reasonable decisions on the basis of this analysis. A table (or a formula, called probability function) summarizing the in-formation about 1. possible outcomes of the RV (numbers, arranged from the smallest to the largest) 2. the corresponding probabilities is called the probability distribution. a) f is complex differentiable in a ∈ D if limz→a f(z)−f(a) z−a … rolling a … Every business small or big uses statistics for its daily function.

Also, useful in determining the distributions of functions of random variables Probability Generating Functions P(t) is the probability generating function for Y Discrete Uniform Distribution Suppose Y can take on any integer value between a and b inclusive, each equally likely (e.g. ! A statistic is a number that can be computed from the sample data without making use of any unknown parameters. 3 The 2-Sample \correlated sample" t-test for comparing two means with correlated or repeated-measures data. Today, there is hardly any business that functions without the use of statistics and statistical tools. The quantile function (or inverse distribution function, if you wish) is defined by F−1(y) = inf{x : F(x) ≥ y}. What was the main goal that presenters were trying to achieve with their slide decks?
