Module summaryThis module extends the ideas introduced in MATH1710, using approximating distributions to estimate quantities of interest in the population using a frequentist approach. We model relationships between variables, including data arising from both related and independent samples. Inferential methods are used to compare the means of two populations, eg to compare the average wages of males and females doing similar occupations. Where two variables are related, the nature and strength of the relationship can be examined by regression procedures. The module also includes techniques relevant to the analysis of count data and tests concerning proportions.
ObjectivesOn completion of this module, students should be able to:
(a) describe properties of key distributions and understand simple inference
(b) with the aid of a statistical package, carry out appropriate hypothesis tests on the means of one or two populations
(c) understand and carry out simple least squares linear regression
(d) carry out inference on proportions
(e) carry out chi-squared tests
1. Sampling distributions and central limit theorem.
2. Frequentist statistical inference. Iid random variables. Point estimation and interval estimation. Confidence intervals for mean (variance known and unknown).
3. Hypothesis testing for means. p-values. Tests concerning means. z-test. T-test.
4. Inference for two populations. Two independent samples. Paired samples.
5. Several random variables. Sample covariance and correlation. Continuous bivariate distributions. Properties of expectations, population covariance, correlation. Linear combinations of random variables.
6. Regression. Least squares regression. Inference concerning slope.
7. Binary data. Hypothesis tests for a population proportion. Large sample confidence interval for a population proportion. Comparing two proportions.
8. Chi-squared tests. Single sample classified into two or more groups. Fitting distributions, for example binomial, geometric, Poisson, normal. Goodness of fit tests. Contingency tables and test of independence.
