The aim of this unit is to provide students with an understanding of how management information and decision-making are enhanced by the application of statistical methods.
Who Should Attend?
Learners who want to develop skills in statistical methods which can be used in all kinds of research problems
Students will learn about a range of statistical techniques and how they can inform management thinking. While studying the unit they will develop their numerical abilities and increase their confidence in handling data in order to create information and knowledge
- Evaluate business and economic data/information obtained from published sources
Interpretation of business and economic data: The nature of data and information, and how data can be turned into information and information into knowledge. Interpreting data from a variety of sources using different methods of analysis: descriptive, exploratory and confirmatory.
- Analyze and evaluate raw business data using a number of statistical methods
Statistical methods that are used to analyses and evaluate data:
Differences between qualitative and quantitative raw data analysis.
Descriptive statistics: Measures of central tendency (e.g. mean, median).
Measures of variability (e.g. range, standard deviation).
Application to business data (e.g. finding average earnings, measuring variability in business processes such as queuing times and customer arrival rates).
The difference between sample and population.
Different sampling techniques and methods.
Use of scatter plots, correlation and regression analysis, simple forecasting.
Business applications such as the association between output and cost, advertising and sales.
Evaluating use of software such as Excel and SPSS to perform raw data analysis.
Applying the appropriate methods and tools for evaluation of raw data.
- Apply statistical methods in business planning
Statistical methods for business planning:
Applying statistical methods to a number of areas of business planning and operations management, including inventory management and capacity management.
Measures of variability:
The issue of variability in business processes (e.g. arrival rates of customers and time taken to deal with customers), and how this leads to a trade-off between waiting time and process utilization.
Statistical process control in quality management.
Measures of probability:
Probability distributions and application to business operations and processes.
Normal distribution (e.g. weights and measures regulations and statistical process control), Poisson distribution (e.g. customer arrival rates) and binomial distribution (e.g. inspection sampling).
Inference (e.g. margins of error and confidence limits).
- Communicate findings using appropriate charts/tables
Choosing the most effective way of communicating the results of your analysis and variables.
Nominal, ordinal and interval/ratio levels.
Different types of charts/tables and diagrams:
The use of frequency tables, simple tables, pie charts, histograms, frequency curves and normal curve.
Advantages and disadvantages of different types of methods.
Presentation of information using tables and charts.
Software for producing charts/tables (e.g. Excel).
