Description

This module will provide the student with the tools necessary to plan, conduct and analyse experiments. The analytical interpretation of these results will allow the student to optimise products and processes.

### Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Calculate correlation coefficient and conduct a test of significance.

2.

Solve simple linear regression and curvilinear regression problems and make predictions.

3.

Conduct one way and two-way ANOVA including the analysis of residuals.

4.

Conduct  and  factorial experiments and analyse the resulting data.

5.

Apply Taguchi methods involving calculation of loss function and signal-to-noise ratios.

6.

Describe when and how to apply the appropriate experimental techniques and models

7.

Use a statistical package to analyse and interpret experimental data.

### Teaching and Learning Strategies

Real world examples, case studies and published peer reviewed papers will be utilised, where possible.

### Module Assessment Strategies

Students will plan, conduct, analyse and interpret their own non-industrial experiment using Minitab software.

Final 2.5 hour written exam.

Prerequisites
MATH08005 201300 Statistics

### Indicative Syllabus

1. Correlation : Meaning of correlation coefficient (r).Hypothesis test on correlation coefficient. Spearman's Rank Order correlation.
2. Regression : Simple linear regression. Making predictions. Confidence intervals and hypothesis testing. The coefficient of Determination. Curvilinear regression and use of transformations. Computation of Multiple Regression via computer.
3. Analysis of Variance : One and two way ANOVA. Comparison of treatment means - Least Significant difference. Analysis of Residuals. Randomised block designs.
4.  Factorial designs : Planning and conducting industrial experiments, blocking, replication, randomisation. Analysis of variance. Calculation of main and interaction effects. Development response graphs. Development of a model which relates response to the factors. Model adequacy checking. Dealing with single replicates of a  design. Construction of blocks in a  design.
5.  fractional factorial designs : Their construction and analysis. Design resolution, confounding patterns and generating relations. Fold-over designs.
6. Taguchi methods: The philosophy. Loss function. Approach to parameter and tolerance design. Inner and outer Arrays. Linear graphs, Data analysis using Taguchi methods. Comparison of Taguchi experimental designs and data analysis methods with western methods.
7. Brief introduction to Random vs. Fixed effects models and Crossed vs. Nested designs.
