Artificial Intelligence Chatbots as an Educational Tool for Statistical Analysis Among Dental Students

July 2, 2026 updated by: Rowan Elshabrawy

Usability and Efficacy of Artificial Intelligence Chatbots as an Educational Aid for Statistical Data Analysis Among Dental Students: A Randomized Crossover Trial

The goal of this randomized crossover trial is to learn if ChatGPT-5.2 is usable and effective as a supplementary educational tool for teaching statistical data analysis to fifth-year undergraduate dental students. The study will also compare ChatGPT-5.2 with conventional statistical tools, such as Microsoft Excel and online statistical calculators.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The efficacy of technological tools for completing the statistical analysis assignments.
Time Frame: 21 days

Efficacy will be evaluated by comparing participants' performance scores across the two tools (AI-ChatGPT-5.2 and conventional tools). Scores will be calculated as the percentage of correct answers in the two assignments.

Score = (Number of correct answers)/(total number of questions)×100
21 days
The usability of the technological tools for completing the statistical analysis assignments
Time Frame: 21 days

Usability is defined as "the extent to which a product can be used by specified users to achieve specific goals with effectiveness, efficiency, and satisfaction in a specified context of use. it will be assessed using system usability questionnaire(SUS), SUS yields a single number representing a composite measure of the overall usability of the system being studied. Note that scores for individual items are not meaningful on their own.

To calculate the SUS score, first sum the score contributions from each item. Each item's score contribution will range from 0 to 4. For items 1,3,5,7,and 9 the score contribution is the scale position minus 1. For items 2,4,6,8 and 10, the contribution is 5 minus the scale position. Multiply the sum of the scores by 2.5 to obtain the overall value of SU.

SUS scores have a range of 0 to 100.
