Subject Knowledge
Aims
To introduce the main concepts of statistical
inference through point and interval estimation, and hypothesis testing.
The likelihood function and maximum likelihood estimate, key concepts in much
modern statistical analysis, are also introduced.
Learning Outcomes
Students should know
what is meant by an estimate, an estimator, and a sampling distribution;
understand what is meant by an unbiased estimator;
know the mean and variance of the sampling distribution of the sample
mean;
know how to write down a likelihood function and find a maximum likelihood
estimate for simple models.
Students should
have an informal understanding of the process of hypothesis testing and
the meaning of
-values and
know what is meant by a confidence interval and the relationship
between confidence intervals
and hypothesis tests.
Methods
Class sessions with some handouts.
Assessment
Marked problem sheets and examination.
Subject Skills
Aims
To provide students with the
ability to calculate estimates and make
inferences about the parameters of some
simple statistical models.
Learning Outcomes
Students will have an understanding of some
basic statistical concepts
including point and interval estimation,
and hypothesis testing.
They will also have the
ability to implement and interpret the results of some simple
statistical procedures, and recognise when such procedures are appropriate.
Methods
Class sessions.
Assessment
Marked problem sheets and examination.
Explanation of Pre-requisites
The module MA1061 provides the basic probabilistic ideas for
an introductory course in statistical methods.
Course Description
Statistics and statistical statements are almost unavoidable in many areas
modern science.
This course introduces some of the central ideas of modern statistical
reasoning, and presents a
number of the more basic procedures of elementary applied
statistics.
Syllabus
Basic graphical methods and descriptive statistics.
Different approaches to inference.
Point estimation; mean squared errors, variance and bias. Estimates, estimators
and sampling distributions. Standard unbiased estimators of a population mean
and variance. Likelihood and the maximum likelihood estimator.
Hypothesis testing and confidence intervals. Inferences for the normal, binomial
and Poisson distributions. Comparing two populations. Small sample results for
normal populations; the
-test. Paired and unpaired samples, the
and
distributions.
Simple examples of the
goodness-of-fit test.
