Statistical Consulting – Research Methodology

We provide ample instruction on the methods used. For example, we determine the ideal sample size using a power analysis. The sample size is calculated from statistical power, effect size, and significance level. In addition, we operationalize your hypotheses and research questions. Additionally, our statistical consultants select variables based on the hypothesis that they test. Finally, we assist you in the design phase of your research.

Statistical Consulting – Data Management

Our statistical consultants can input, organize, code, merge, clean, and manage your data. In addition, we can get your dataset ready for analysis. Additionally, we create composite scores, work with missing data, and label data. Our statistical consultants can detect and correct corrupt or inaccurate records from a database. The process of data cleaning includes data auditing, workflow specification, workflow execution, post-processing, and controlling. We can use popular methods (e.g., parsing, data transformation, duplicate elimination). Additionally, we run outlier analyses such as a box plot. In addition, our statistical consultants can examine any standardized residual greater than about 3 in absolute value. Finally, we can find unexpected and erroneous values by analyzing the data.
