Description Biometry introduces students to various statistical techniques necessary in scientific endeavours. Presentation of the content will emphasise the correct principles and procedures for collecting and analysing scientific data, using a hands-on approach. Topics include effective methods of gathering data, statistical principles of designing experiments, error analysis, describing different sets of data, probability distributions, statistical inference, non-parametric methods, simple linear regression and analysis of categorical data.

Learning Outcomes
On successful completion of this subject, students should be able to:
- apply the basic principles of statistical design incorporating error analysis
- design a simple scientific experiment, and then carry out and analyse the data obtained
- estimate population means using confidence intervals
- test hypotheses about population means using parametric techniques and find appropriate sample sizes for experiments
- use regression and correlation techniques to describe relationships between variables
- use the chi-square test for goodness of fit and test for independence to analyse categorical type data
- develop statistical computing skills as part of a 'tool-kit' for solving statistical problems. (R-commander)
Subject Content
1. Overview - What is Statistical Thinking? And what role does in play in Scientific Research.
2. Gathering Data - Types of data and dealing with measurements
3. Statistical Principles of Design - understanding randomness; types of sampling including observational studies, experiments, blocking and stratification, and levels of replication; sampling concerns.
4. Describing Sets of Data - Qualitative data; graphical methods for describing quantitative data; numerical measures of central tendency and variability; dealing with errors; error bars
5. Basic probability concepts; enough to understand p-values, confidence intervals and independence. Normal distributon and methods for assessing normality; use of transformations to meet assumptions; sampling distributions; the Central Limit Theorem.
6. Estimation with Confidence Intervals: Single sample - Large and small sample confidence intervals for a population mean; determining the sample size.
7. Tests of Hypothesis: Single sample - Elements of a statistical test; type I and type II errors; large and small sample test of hypothesis about a population mean; p-values.
8. Comparing Population Means: Estimation and Hypothesis testing - Comparing two population means: independent sampling and paired difference sampling; comparing three or more population means: one-way and two-way ANOVA;
9. Simple Linear Regression and Correlation - Least squares approach; assessing the usefulness of the model; using the model for estimation and prediction; the coefficients of correlation and determination.
10. Analysis of Categorical Data - Test for independence and 'Goodness-of-fit' test.
