This bell curve graph shows multiple Z-scores (Mean 100, Standard Dev 15), allowing you to visually compare results from up to 10 different assessment instruments.
The chart was designed using principles of effective data visualization to promote parent/teacher comprehension (the subject of my master's action research project).
Data entry is streamlined and intuitive. Simply enter the name of the assessment as you would like it to appear on the graph, enter the score, and you're done.
Formatting instructions are included for fine-tuning and including in reports.
