iAdapt Survey Analysis

Introduction

This notebook contains the data analysis of pre- and post survey results relating to phase I of the iAdapt project. The notebook is also available as a PDF.

In step 1, Likert data from the results were first converted to ordinal values, then analysed using the Mann-Whitney U and t tests. Statistically significant question results had a Cohen's d and Hedge's G effect size assigned.

In step 2, pre- and post question data were graphed in small multiples according to their capability grouping, for further discussion.

QA and Data Integrity

Start time and response ID were not used in this analysis but are retained for data quality and assurance reasons, allowing them to be matched with the retained read-only survey response data if necessary.

Installation

If you wish to reproduce this analysis, install the requisite python packages from requirements.txt, then open the notebook using Jupyter.
