Testing unrelated samples - Statistical analysis of two sets of unrelated data using the software IMB SPSS. Provided data will be classified as either parametric or non-parametric data. If the data is parametric it will be analysed using an independent samples t-test. If the data is non-parametric it will be analysed using a Mann-Whitney U test.

Tests on frequencies - Statistical analysis of frequencies using the software IBM SPSS. Using the chi-squared test frequencies of a desired variable, provided data will be analysed. Both one way and two way analysis will are offered.

Correlation analysis -
Data provided will be classified into either parametric or non-parametric, then analysed to determine whether the variables correlate and have a cause and effect relationship. Univariate, bivariate and multivariate analysis are all offered.

Regression analysis - Data analysis for analysing of a relationship between an independent/dependent variable pair in relation to specific indicator variables.  Offered for both parametric and non-parametric data.  

Time series analysis - Analysing data patterns over time is a widely used statistical technique. A time series analysis can not only be used to analyse past data, it can also be used to recognise past patterns and predict how a trend will continue in the future. Using R statistical analysis software, a time series analysis will be conducted for any provided data.

Testing related samples - Statistical analysis of two sets of related data using the software IBM SPSS. Provided data will be classified as either parametric or non parametric to determine the most appropriate test for your specific data. Parametric data will be analysed using paired t-tests to determine whether there is a statistically significant difference in the means of the two data sets.Non-parametric data will be analysed using Wilcoxon signed rank tests. For three or more data sets of parametric data a one-way ANOVA technique will be used. Post-hoc testing is an additional service. For three or more non parametric data sets a Kruskal-Wallis test will be conducted.
