Area of Research The research seeks to investigate the entrepreneurial success in electronic commerce. Previous research has identified several drivers and impediments to success and the study will mitigate those drivers and impediments to assist an entrepreneur in achieving success as a reseller of tangible goods. Types of Measurement In my research‚ the variables are categorized into two groups: success drivers and impediments to success. The one thing that is common in these items being

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

shorter than TT Air‚ it does not significantly affect the output as the one day does not change much (unless there had been a market shock). However based on Central Limit Theorem‚ if the sample size is greater than or equal to 30 samples‚ the sample statistics reflect the time population parameters. • The Median data does not show much in this case as the range (4.7 AA Fly and 6.8 TT Air) is small for both AA Fly and TT Air. This means that the mean is more applicable to be used. • The Mode of AA

a) A company is interested in providing a new benefit to its employees to encourage them to utilize public transportation. To study the potential of providing this benefit‚ the company would like to do a survey of the workers at a company to gather information on why do or do not use public transportation for commuting to work. The company is about 25‚000 people in areas where public transportation is available. You also want to find out the reasons why their choice is what it is. In this case

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

IMPORTANCE OF STATISTICS In today’s world we are faced with situations everyday where statistics can be applied. Statistics can be used to determine the potential outcome of thousands of things where the human mind alone wouldn’t be able to. Statistics benefits all of us because we are able to predict the future based on data we have previously gathered. Being able to predict the future not only changes our lifestyle but also helps us be more efficient and effective. Statistics is the science of

successful that after World War II many companies used similar techniques in managerial decision making and planning. The decision making task of modern management is more demanding and more important than ever. Many organisations employ operations research or management science personnel or consultants to apply the principles of scientific management to problems and decision making. In this module we focus on a number of useful models and techniques that can be used in the decision making process
