Project Stat. Math 5389 Graph Analysis# 1Spring ‚ 2012Noemi Bores | Identifying Misleading Graphs Graphs are pictorial representations of numbers. Therefore‚ at the least‚ we should expect that the representation of the numbers be proportional to the numbers themselves. Unfortunately‚ this is not always the case. In some cases this occurs because the graph designer wants to give the impression of better performance than is actually the case. In other cases‚ the designer might not have any

Statistics is the study of the collection‚ organization‚ analysis‚ interpretation and presentation of data. It deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments. Descriptive statistics is the discipline of quantitatively describing the main features of a collection of information‚ or the quantitative description itself. Descriptive statistics are distinguished from inferential statistics (or inductive statistics)‚ in that

Lecture 1. Descriptive statistics includes statistical procedures that we use to describe the population we are studying. The data could be collected from either a sample or a population‚ but the results help us organize and describe data. Descriptive statistics can only be used to describe the group that is being studying. That is‚ the results cannot be generalized to any larger group. Inferential statistics is concerned with making predictions or inferences about a population from observations

Inferential Statistics and Findings Erick Mart QNT/561 August 25th 2014 Mario LOPEZ Inferential Statistics and Findings Inferential Statistic is the process of drawing conclusions from data that are subject to random variation‚ for example‚ observational errors or sampling variation. Our team uses inferential statistic to compare two groups‚ which are Melks and DHL. This paper outlines the sampling and data collection procedure used to test the null hypothesis. The null and alternate hypotheses

INTRODUCTION Gozinto Chart named after an Italian mathematician Professor Zepartzat Gozinto is from the word ‘goes into’ is used to provide overall microview of how materials and subassemblies are united to form finished products. It is often called Assembly chart (Shim and Siegel‚ 1999) In other words‚ it is a pictorial representation of a product that shows how the elements required to build a product fit together. Gozinto Chart is a schematic model that defines how parts go together‚ the order
