Why Statistics Causes So Many Students to Stall
Quantitative data analysis is the stage where many dissertation students hit a wall. You may have collected clean, well-structured data — but when it comes to choosing the right statistical test, running the analysis, interpreting the outputs, and writing them up in academically rigorous language, the confidence simply is not there.
This is not a personal failing. Most taught degree programmes include one or two statistics modules — rarely enough to prepare students for the specific demands of dissertation-level analysis. The gap between knowing that regression exists and knowing which regression model to use, why, and how to interpret the coefficients is significant. That is the gap our specialists bridge.
Statistical Tests Commonly Required in Dissertations
| Test | When to Use | Common Software |
|---|---|---|
| Descriptive Statistics | Always — to summarise your sample | SPSS, Excel, R |
| Independent Samples t-test | Comparing means of two independent groups | SPSS, R |
| One-Way ANOVA | Comparing means across three or more groups | SPSS, R |
| Pearson / Spearman Correlation | Testing relationships between two variables | SPSS, Excel |
| Linear / Multiple Regression | Predicting a continuous outcome from predictors | SPSS, R, Stata |
| Logistic Regression | Predicting a binary categorical outcome | SPSS, R |
| Chi-Square Test | Testing relationships between categorical variables | SPSS, Excel |
| Factor Analysis / SEM | Scale validation, structural modelling | SPSS, AMOS, R |
Choosing the Right Statistical Test
Selecting the appropriate test is not simply a matter of matching your data type to a list. It requires understanding your research questions, the level of measurement of your variables, the distribution of your data, and the assumptions each test requires. Common mistakes include:
- Using parametric tests (like t-tests or ANOVA) on data that violates normality assumptions
- Running multiple independent t-tests instead of ANOVA, inflating Type I error
- Confusing correlation with causation in regression write-ups
- Failing to report effect sizes and confidence intervals alongside p-values
- Ignoring multicollinearity in multiple regression models
What Examiners Expect in the Results Chapter
Statistical results must be reported following APA (or your field's equivalent) conventions. This means including the test statistic, degrees of freedom, p-value, and effect size for every analysis. Tables and figures must be properly labelled and referenced in the text. The results chapter presents findings objectively — interpretation belongs in the discussion.
A common and costly mistake is burying key findings in complex tables without providing a clear narrative description in the text. Examiners should be able to understand your results from reading the prose alone, with tables providing supporting detail.

Key Takeaways
- Choosing the wrong statistical test — or reporting it incorrectly — can significantly damage your dissertation grade
- Assumption checking is mandatory before running parametric tests: normality, homogeneity, and independence
- Results must be reported following APA conventions, including test statistics, p-values, and effect sizes
- The results chapter presents data objectively; interpretation belongs in the discussion chapter
- Expert statistical support covers test selection, analysis, write-up, and interpretation
