Biostatistical Consulting – Research Methodology 

Our biostatisticians determine the statistical method for the study that you plan to conduct. For example, we determine the ideal sample size by using our statistical expertise. Additionally, we select variables based on the hypothesis that we test. Our biostatistical consultants assist you in the design phase of your research. The type of research design you use is important for finding reliable and valid results. Therefore, we can help you make this decision.

Biostatistical Consulting – Data Management 

Our biostatistical 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 biostatistical 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). We run outlier analyses such as a box plot. In addition, our biostatistical 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.

Biostatistical Consulting – Reliability and Validity

In any research, only conducting the analysis is not enough. Therefore, we ensure that the results are reliable and valid. For example, we can test reliability (e.g., Cronbach’s alpha, test-retest reliability, split-half reliability, inter-rater reliability) and validity (e.g., content validity, construct validity, criterion validity).
