Services Details

Methodology & Research Design Services

Validity Assessment

Rigorously evaluate internal, external, construct, or other forms of validity in your proposed experiment.

Power Analysis

Ensure your studies are adequately powered to detect the expected phenomenon.

Psychometrics

Build and assess questionaries which measure observable or latent phenomena with accuracy and precision.

Implementation Science

Assess and mitigate problems with logistics and delivery of a program for the first time or in a new location.

Program Evaluation

Quantify the impact of a pre-existing program on financial, behavioral, or self-report outcomes.

Analytic Services

Analytic Services represent the largest and most defined branch of Parameter Analytics. If it can be quantified in a table—numerical or otherwise—we can analyze it.

All analytic models are accompanied by:

  • Visualizations

  • Coefficients

  • Model-adequacy tables

  • In-depth & summative interpretations

  • Abstracts & Corporate “TLDRs”

Here, we provide a list of models, approaches, and frameworks frequently used by our analysts.

    • Group Comparisons

    • Multiple Regression

    • Logistic Regression

    • Mediation

    • Moderation & Interactions

    • Clustered & Nested / Hierarchical Data

    • Differential Treatment Effects
