Introduction

A course in basic statistics is offered in a wide variety of disciplines, from the social sciences to business to the natural sciences. The same statistical methods are applied across disciplines. Therefore, it should not be surprising that the tools you will learn to use in this course will benefit you in your future studies and career, regardless of whether your career interest is finance, accounting, strategy, management or marketing. In this course you will learn basic statistical measures, descriptive statistical methods, sampling methodology and the main probability distributions. 

I believe statistics is best taught through a series of clear and carefully worked examples. A theoretical background to descriptive and inferential statistical methods will be provided, however much of the time will be spent teaching you how to apply the theory to the real world. Statistics is not about memorising formulas: it is about recognising the appropriate statistical test to perform in a given situation. This requires practice by the student. As we cover the topics, if you do not have a clear understanding of one topic it is wise to seek help immediately. The next topic will build upon the previous one. Please allow me to assist you as soon as you find that you have any questions.

Syllabus

Lesson 1.Descriptive statistics: concepts, measures, graphs. What is statistics? Descriptive versus inferential statistics. Sample and population. Types of data. Measurements of central tendency. Measurements of dispersion. Measurements of shape. Measurements of concentration. Bar charts and pie charts. Frequency distribution. Other type of graphs. Misleading graphs.

Lesson 2. Bivariate analysis: frequencies, tables, scatter plots, conditional and marginal distribution, measures, etc. Covariance and correlation.

Lesson 3.Probability and distribution functions. Introduction to probability. Classical probability. Tree diagrams. Bayes' theorem. Moments about the origin. Central moments. Discrete versus continuous probability distribution.

Lesson 4.Discrete probability distributions. Binomial probability distribution. Hypergeometric probability distribution

Poisson probability distribution.

Lesson 5. Continuous probability distributions. Normal distribution, Student's t, Chi-squared distribution, F distribution.

 

Teaching and learning activities

In person



Theoretical explanations will be presented in the classroom on PowerPoint slides, accompanied by additional explanations on the board.

The theory will be combined with problem-solving.

Problems will be solved jointly between the lecturer and students as a way of improving the learning process.

Evaluation systems and criteria

In person



Two evaluation methods will be used:

1. Mid-course examination and class participation (30%)

2. Final examination (70%)

The continuous evaluation mark will not be considered for students who resit in June-July.

Bibliography and resources

Students’ proficiency in Statistics 1 will be achieved by means of active practice. This means working on problems and understanding and explaining the results. The various textbooks recommended have hundreds of problems students can use to gain additional practice. Answers to most of the problems can be found at the back of the textbooks.
