Remote teaching of publication‐quality, single‐case graphs in Microsoft Excel

Lehardy et al. (2021) · Journal of Applied Behavior Analysis 2021
★ The Verdict

A free 15-minute Excel video and checklist lifts trainee graph accuracy from 25% to 94%.

✓ Read this if BCBAs who supervise students or RBTs who make graphs.
✗ Skip if Teams already using automated graph software.

01Research in Context

01

What this study did

Lehardy et al. (2021) taught master’s students to make single-case graphs in Excel.

They used a free 15-minute video and a one-page checklist.

Students tried three graph types before and after the training.

02

What they found

Graph accuracy jumped from 25% to 86-96% after the short lesson.

All three graph types showed the same big gain.

The video plus checklist took under 20 minutes total.

03

How this fits with other research

Mondati et al. (2025) built on this idea with a longer 43-minute package.

Their college students hit nearly 100% accuracy, topping the 2021 results.

Earlier papers like Chok (2019) and Deochand et al. (2015) only showed how to build graphs, not how to teach the skill.

Lehardy’s study is the first to prove a quick video can train the skill.

04

Why it matters

You can copy the free video and checklist today.

Play it during supervision and watch graph errors drop.

If you need even better scores, add the 2025 workbook steps later.

03Original abstract

Microsoft Excel is ubiquitous, cost-effective, and can be used to create publication-quality single-case design graphs. We systematically replicated the GraphPad Prism video tutorial by Mitteer et al. (2018) to teach 24 master's students to create multiple-baseline graphs using Excel 2016. Students' mean accuracy on the multiple-baseline graph was 25% in pretraining, 86% with the video tutorial, and 96% with the review checklist. Next, students used the same video tutorial to create multielement and reversal graphs. Students' mean accuracy on the multielement graph was 93% with video tutorial and 94% with review checklist, and accuracy on the reversal graph was 82% with video tutorial and 94% with review checklist. Students reported moderate to high satisfaction with both training components. The results support scientist-practitioners using the video tutorial and review checklists to create three common graphs using Excel 2016, Excel 2019, and Excel Office 365.
