Module Level: Level 2
Module Credits: 5.00
Academic Year: 2020/21
Semester: SEM1
Originating Department: Mathematical Sciences
Pre-requisites: MTH104 MTH113
To introduce statistical methods with a strong emphasis on applying standard statistical techniques appropriately and with clear interpretation.

Interspersed with graphical and robust techniques.

The emphasis is on applications.
Learning outcomes 
A Calculate summary statistics, fitted values and residuals, Construct and interpret ANOVA tables

B Demonstrate understanding of the concepts of: a random variable, a distribution, a statistical model, a parameter, a fitted value and a residual

C Demonstrate understanding of the sum of squares as a tool for assessing the adequacy of a model

D Demonstrate understanding of the principles of hypothesis testing and confidence intervals

E Demonstrate understanding of the significance of regression models and ANOVA tables

F Interpret the output from standard computer packages to draw statistical conclusions

G Be aware of the significance of statistical variability in relation to the interpretation of data and the confidence with which conclusions can be reached

H Be aware that the validity of statistical conclusions depends in the appropriateness of the techniques used, and the skill and independent judgment with which techniques are selected and used and conclusions drawn
Method of teaching and learning 
This module will be delivered by a combination of formal lectures and tutorials.

Point and interval estimation. Unbiased estimators. Confidence intervals for means, proportions, and their differences. Required sample size for given margin of error.

Hypothesis Testing: One Sample

Introduction to hypothesis testing. Acceptance and rejection regions. Type I and Type II errors and their probabilities. Hypotheses about means, proportions and matched pairs, Student t-distribution. Power function of a test involving the mean and proportion. Hypothesis testing and confidence interval for the variance, Chi-squared distribution.

Hypothesis Testing: Two Samples

Distribution of the difference of two sample means and proportions. Comparisons of two means and two proportions, including paired Student t-test. Comparison of two variances, F-distribution.

Chi-square tests

Goodness of fit tests for uniform, binomial, Poisson and Normal distributions. Tests of homogeneity and independence of contingency tables.

Analysis of Variance

One way analysis of variance. Two way analysis of variance.

Linear Regression

Linear regression model, least squares method. Estimation of the intercept and slope, confidence intervals and tests. Predictions and their confidence or prediction intervals. Multiple regression, regression ANOVA and the F-test. Coefficients of correlation and determination. Polynomial regression. Outline of model selection and residual analysis.

Non-parametric Tests/Resampling Methods

Selection of non-parametric tests from the following list: Sign test, Mann-Whitney test, Wilcoxon signed-ranks test, Kruskal-Wallis test, Kolmogorov-Smirnov test, or resampling methods for estimation and test.
