Statistical Analysis
“Water, water, everywhere, and all the boards did shrink,
Water, water, everywhere, Nor any drop to drink.”
Those ancient words of Samuel Taylor Coleridge may well have been uttered regarding data. Today, there is an abundance of data with enormous potential for insights and evidence-based decisions. However, one must sift through the data and make sense of it to uncover underlying patterns and trends. Our data management and statistical analysis services involve collecting, exploring, organizing, and drawing meaningful interpretations from all kinds of data. We serve clients in academia, businesses, pharmaceutical companies or CROs, and other industries. Our data analysts, data scientists, and mathematical statisticians are experts in their trade. They will transform your data into impact!
Quantitative Statistical Analysis
If you collected objective, numerical data for your study, you would need to use quantitative methods for analyzing your data. These methods include, but are not limited to, the following examples.
Parametric hypothesis tests such as:
- Independent T-Test
- Paired T-Test
- ANOVA, MANOVA, ANCOVA, and MANCOVA
- Z-Test for One or Two Proportions
- Calculation of Pearson’s Coefficient
Non-parametric hypothesis tests and procedures such as:
- Mann-Whitney U Test / Wilcoxon Rank Sum Test
- Wilcoxon Signed-Rank Test
- Kruskal-Wallis Test
- Friedman Test
- Chi-Squared Test
- Fisher’s Exact Test
- McNemar Test
- Calculation of Spearman’s Coefficien
Qualitative Statistical Analysis
If you collected textual data from interviews, documents, observations, or even web scraping, you would need qualitative methods. Some well-known qualitative research designs include:
- Phenomenological Studies
- Grounded Theory Studies
- Case Studies
- Ethnographic Studies
- Action Research
- Historical Studies
Software Preferences
We use Stata, R, and SPSS for quantitative analysis. For qualitative analysis, we use NVivo. We are often able to accommodate other software preferences if you ask. Rest assured, for most analyses, you will obtain the same results, regardless of the software used.
