SummaryThis course will provide training in the foundational principles of analytical chemistry. The considerations required for developing a successful unbiased sampling strategy will be discussed; as well as statistical methods for the processing of a range of data. The course forms a part of the curriculum for any student enrolled on the PGT MSc degree course in Analytical Chemistry.
Course description The course consists of a blend of lectures, tutorials and workshops, which deal with the key concepts of analytical chemistry and data sampling and statistics. Students will be assessed on their performance in problem-based coursework. The course topics include:

An introduction to Analytical Chemistry -
- Importance of and areas of applications of qualitative/quantitative analyses
- The Analytical Process
Sampling -
- Sampling and sampling strategies: random, systematic, judgmental. Temporal factors in sampling.
- Principles of Quality Assurance, Quality Assessment and Quality Control; use of standards, calibration, blanks, controls, certified reference material and traceability, spikes and duplicates.
- Multifactorial Experimental Design. Design of Experiments (DoE)
Statistical Methods -
- Parametric versus non-parametric methods.
- Precision, accuracy, and random and systematic error; propagation of errors.
- Data Distributions. The normal and log-normal distributions; mean, median, range and standard deviation; confidence limits of the mean; use of significant figures.
- Analysis of non-normal data.
- Significance testing and null hypotheses; one and two tailed tests; type I and type II errors; parametric tests on means (paired and unpaired t-tests); parametric test on spreads (F-test).
- Non-parametric tests on medians (sign test, Wilcoxon rank sum test, Mann-Whitney U-test). Non-parametric test on spreads (Siegel-Tukey test).
- Linear and non-linear regression.
- One-way and two-way analysis of variance (ANOVA); correlation (Pearson and Spearman rank correlation coefficients); significance of the correlation coefficient.
- An introduction to multivariate analysis. Principle component Analysis, Hierarchical Cluster Analysis
- Data visualisation. Assessing the best way to represent complex data. Charts, plots, histograms, scatter plots, heat maps.

The formal lectures will be supplemented by -
- Workshops which will include the discussion and analysis of several case studies┬┐ (i) data analysis/ statistics (ii) data visualisation.
- Practical laboratory sessions
- Non-assessed data visualisation competition
