Data Analysis

Statistical analysis provides important lines of evidence for answering key study questions and hypotheses. As a result, the accuracy and defensibility of your study conclusions depend on the use of the appropriate statistical tests and interpretation. The analysis of environmental data is often constrained by small sample sizes and data distributions that do not meet assumptions for some statistical tests. Clear Viz Aquatic is well versed in the limitations and assumptions of a variety of statistical tests. Therefore, we will quickly select the appropriate statistical test. We use both parametric and non-parametric methods. Clear Viz Aquatic utilizes R Statistical Software to conduct efficient statistical analysis and generate high quality figures and tables.
