  Appropriateness to the current study.
  Published reliability and validity values relevant to their use in the study.
• For all researcher instruments providing:
  Basis for development (literature sources or other bases for development)
  Plan to provide evidence for reliability (e.g., internal consistency and test/retest) and validity (e.g., predictive and construct validity).
• Identifying software used for analyses.
• Explaining data cleaning and screening procedures.
• Describing in detail the analysis plan, including the elements below including:
  Statistical tests that will be used to test the hypothesis (es).

Results

We can improve your dissertation’s results chapter. We can assist you with:

• Reporting statistical analysis findings, organized by hypotheses

Discussion

We can help our dissertation consulting clients with:

• Describing in what ways findings confirm, disconfirm, or extend knowledge in the discipline by comparing them with what has been found in the peer-reviewed literature described in chapter 2.
• Stating the limitations to trustworthiness that arose from the execution of the study.
• Discussing recommendations for further research that are grounded in the strengths and limitations of the current study. We can ensure recommendations do not exceed study boundaries.
• Depicting the potential impact for positive social change at the appropriate level.

Dissertation Consulting – Data Management

We are dedicated to detecting and correcting corrupt or inaccurate records from a record set, table, or 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, duplicate elimination, and statistical methods.

By analyzing the data using the values of mean, standard deviation, range, and clustering algorithms, we can find values that are unexpected and thus erroneous. We can examine any standardized residual greater than about 3 in absolute value, Hat element greater than 3p/n (p=k+1, k degrees of freedom), a Cook’s distance > 1, and Mahalanobis’s distance for a case. We run outlier analyses such as a run-sequence plot, a scatter plot, a histogram, and a box plot.
