Statistical Consulting for Professors and Researchers – Research Methodology and Research Design

statistical consulting for professors and researchers

Our statisticians provide ample instruction on the methods used. For example, we determine the ideal sample size by 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, we select variables based on the hypothesis that we test. Finally, our statistical consultants assist you in the design phase of your research.

Statistical Consulting for Professors and Researchers – Data Management

statistical consulting for professors and researchers

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.

We are dedicated to detecting and correcting 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. These include parsing, data transformation, and duplicate elimination.

By analyzing the data, our statistical consultants can find unexpected and erroneous values. In addition, we run outlier analyses such as a box plot. Additionally, we can examine any standardized residual greater than about 3 in absolute value.

Statistical Consulting for Professors and Researchers – Reliability and Validity

statistical consulting for professors and researchers

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).

Statistical Consulting for Professors and Researchers – Interpretation of the Results

statistical consulting for professors and researchers

Our statistical consultants interpret the research results. We also explain the results of the study. In addition, we write up all the results, including tables and figures. Our statisticians also provide syntax and the raw output file. Additionally, we ensure you are comfortable with the analyses. Finally, our statistical consultants allow unlimited email and phone support to ensure that you completely understand the analysis results. Typical results sections include:

Conduct descriptive statistics;
Test the assumptions of the analyses;
Perform analyses to examine the research questions;
Draft results write-up, which includes documenting assumptions, interpreting findings, stating support or non-support for the hypotheses, and providing tables and figures.

Qualitative Research

We can help you with any or all of the following steps:

  • Establishing and operationalizing your research questions
  • Providing ample instruction on the methods used
  • Coding, thematizing and providing reporting of findings for a study
  • Identifying themes and sub-themes
