Data Cleaning, Screening & Preparation
Why This Step Matters
Even the strongest research design will fall apart if the data behind it is messy. Outliers, missing values, inconsistent coding, or improperly formatted variables can derail your entire analysis before it begins. This service makes sure your data is trustworthy, organized, and fully ready for the statistical work your dissertation depends on.
When You Need This Kind of Help
This service is for you if you feel uneasy every time you open your dataset and see errors, duplicates, or values that don’t make sense. It helps when your chair says your data “isn’t ready for analysis yet” or asks you to explain decisions you haven’t fully made. Many students come in with datasets full of missing responses, extra columns from survey platforms, or mixed coding formats that make simple analysis impossible. If your data feels unmanageable or you’re afraid of making the wrong decision with screening or outliers, you’re in the right place.
What You’ll Receive
A fully cleaned dataset with errors, duplicates, and inconsistencies removed.
Screening for missing values with clear handling strategies documented.
Identification and assessment of outliers based on your study’s method.
Proper coding and recoding of categorical, ordinal, and scale variables.
Standardization of formatting so every variable is analysis-ready.
A check for assumption-related issues (normality, linearity, range, etc.).
A documented record of all cleaning decisions for your dissertation write-up.
A preparation summary describing how your cleaned dataset is structured.
Output files formatted for SPSS, R, Excel, or your chosen platform.
A dataset that is fully ready for statistical testing without surprises.
Why Students Trust Us With This Work
Your data is reviewed and cleaned by U.S.-based PhDs who understand how committees assess data quality and how fragile statistical results become when screening is done incorrectly. This is careful, human-driven work, not automated scripts or shortcuts, ensuring your dataset reflects your study accurately and ethically.
How We Work Together
To prepare your data properly, we’ll ask for your raw datasets, survey instruments, variable descriptions, export files, and any guidance from your chair or university. You share the source material; we turn it into a dataset you can trust when you move into analysis.

Your files and participant information remain fully confidential.
All cleaning decisions follow ethical, university-aligned standards.
Nothing is changed in a way that compromises your study’s integrity.
Revisions within the scope of the service are welcomed for clarity.
