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. When asked, … 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. Gradually, the subject became more and more popular and its application has become more extensive. (n 1 k + 1)! In practice, we often use a statistic to estimate an unknown parameter. In the case in which the function is neither strictly increasing nor strictly decreasing, the formulae given in the previous sections for discrete and continuous random variables are still applicable, provided is one-to-one and hence invertible. Introduction to CHAPTER1 Statistics LEARNING OBJECTIVES After reading this chapter, you should be able to: 1 Distinguish between descriptive and inferential statistics. distribution of three classic test statistics: 1 The 1-Sample Student’s t-test for a single mean. Key aspects of statistics include finding averages/means, determining outliers on either end of a bell curve, and finding the range of quantities for set points.

INTRODUCTION The word statistics conveys a variety of meaning to people in different walks of life. To find the most frequently occurring number, use the MODE function. ” Although not every statistician would agree with this description, it is an inclusive starting point with a solid pedigree. Statistics is a crucial process behind how we make discoveries in science, make decisions based on data, and make predictions. It also deals with Mode. Let D ⊂ C be open, f: D → C, z = x +iy, f = u+iv. 1.
