The above link will help you plan your project, step-by-step, by building up the necessary mathematical and statistical techniques.

Identifying an appropriate Hypothesis Test

Before attempting to identify an hypothesis test, it is necessary for you to be clear about the experimental factors involved in your project, the distribution and uncertainties of your measurement variables, and your detailed objectives. This preparative work is covered in the project plan (above),  stages 1 to 3, and must be completed before clicking below:

Introduction to Research Planning

When you first think about your research project, you will probably have some general idea that you will make some measurements, which you will then analyse in such a way that you can present your results and arrive at a conclusion.

As the above example shows, it is at the start of the project that you need to think very carefully about exactly what you will measure - how often, how accurately, and under what experimental conditions.
Expand/Reduce - additional text: >>

General Principle – Collecting more data (provided that it is planned in advance) will increase the quality and/or range of conclusions that you can extract from that data. However, you must not try to collect more data than is reasonably possible in the time available.

Initial Planning Constraints

Approvals - ethics, health and safety
Identifying analytical techniques to match experimental data
Access to resources - equipment, technical support
Availability of materials
Booking experimental time
Unexpected problems and results


Consider this ....

Choice of measurements must match the available data analysis software
Frequency counts for chi-squared
Requirements for normal distribution
Use of repeated measures (pairs)
Uncertainty - number of replicates - precision - power of test - available time/resources - no of factor levels
