SHEB405 Принципи на бизнес статистика

Анотация:

This introductory unit provides an understanding of the basic statistical methods required for the study of business related problems. The unit introduces students to the assumptions, concepts and techniques used by statisticians to make decisions. This unit focuses on descriptive statistics, probabilities and probability distributions, inferential statistics and regression analysis.

This unit aims to:

• develop basic statistical skills so students can apply them to business problems.

• give emphasis to methods of estimation and hypothesis testing which have a potential role in a manager’s decision-making process.

• introduce regression analysis so students can apply it to business problems.
