Running the test is the easy part. The marks are in choosing the right one, checking its assumptions, and explaining what the output means in words a marker will credit.

Choosing a test comes down to three things. How many groups or variables you have. What type of data they are. And whether your data meet the parametric assumptions. Students who pick a test because it came up in the lecture usually pick the wrong one, and clean output cannot rescue the wrong test.
| Your question | Parametric test | Non-parametric alternative |
|---|---|---|
| Two independent groups differ? | Independent-samples t-test | Mann-Whitney U |
| Same group, before and after? | Paired-samples t-test | Wilcoxon signed-rank |
| Three or more groups differ? | One-way ANOVA | Kruskal-Wallis H |
| Two categorical variables related? | β | Chi-square test of independence |
| Strength of a relationship? | Pearson correlation | Spearman's rho |
| Predicting a continuous outcome? | Multiple linear regression | Robust or quantile regression |
| Predicting a binary outcome? | Binary logistic regression | β |
| Reducing many items to factors? | EFA / PCA | β |
Reporting a t-test without evidence that you checked its assumptions is the fastest way to lose the analysis marks. We test them, report them properly, and if an assumption fails we say so and switch to the appropriate alternative rather than quietly proceeding.
Qualitative work has its own rigour, and βthemes emerged from the dataβ is not evidence of it. We use Braun and Clarkeβs six-phase thematic analysis by default. It is the most widely accepted framework in UK social science, health and education, and it leaves an auditable trail.
You get the NVivo project file or a coding framework in Excel, a codebook, the theme hierarchy, and a reflexivity statement. UK examiners increasingly expect that last one, and students routinely leave it out.
Every quantitative order comes with annotated syntax β an SPSS .sps file, an R script or a Stata do-file. This is not a nicety. It means you can rerun the whole analysis yourself. It means your supervisor can check it. And if a viva panel asks how you got a figure, you can show them.
Why students pick us for this.
SPSS, R, Stata, Excel, Python and NVivo.
You see the price before you commit. Every order comes with a free similarity report, and we rework it free as many times as you need.
Every order comes back with all of this.
Send us your brief and we will tell you which service you need. Often it is a cheaper one than you expected β we will say so.
Ask a specialistSPSS, R, Stata, Excel, Python and NVivo. Tell us what your department has licensed, since deliverables should be openable on your own machine.
Yes, and this is the better time to talk to us. Sample size calculation, questionnaire design and scale selection before collection prevent the problems that cannot be fixed afterwards.
That is the point of the annotated syntax and the written interpretation. Students facing a viva can also book a walkthrough call to rehearse the questions examiners actually ask.
Yes β our dissertation SPSS page covers the full findings-and-analysis chapter, which is a larger piece of work than a standalone coursework analysis.
