Short Title:  Statistics for Marketing Purposes 

Full Title:  Statistics for Marketing Purposes 

Module Contributor:  Colm McGuinness 

Module Description:  This module will expose students to fundamental statistical techniques, and develop analytical problem solving skills. 

Learning Outcomes: 
On successful completion of this module the learner will be able to 
 Summarize large sets of data, including grouped data, using the standard measures of central tendency and dispersion and their definitions and properties, and represent it graphically.
 Determine the nature and strength of linear relationships within bivariate data using least squares techniques and product moment correlation, and create seasonally adjusted forecasts from time series data.
 Apply the laws of probability, in particular the concept of a random variable and its distribution, the meaning of expected values, and the properties of common distributions such as the normal, binomial, Poisson and exponential distributions.
 Interpret the concept of a statistic as a random variable arising from sample data, with the central limit theorem determining the behaviour of such statistics and thereby underpinning the idea of a statistical test.
 Frame and use an appropriate test for a simple statistical problem, based on their knowledge of hypothesis testing and the central limit theorem.
 Implement techniques learnt using a modern computer package, such as Excel or SPSS.
