Updated 1.2: Now includes adjustable Range Markers
Update 1.1: Now includes Scaled Scores
This bell curve graph shows results from multiple assessments in both Standard Score (Mean 100, SD 15) and Scaled Score (Mean 10, SD 3) formats allowing you to visually compare results from up to 10 different assessment instruments on one graph.
The chart was designed using principles of effective data visualization to promote parent/teacher comprehension (the subject of my master's action research project). I also find it helpful for quickly spotting trends and reaching my own professional conclusions.
Data entry is streamlined and intuitive. Simply enter the label of the assessment as you would like it to appear on the graph, enter the score and score-type, and you're done.
Formatting instructions are included for fine-tuning and including in reports.
Purchase includes all future updates at no cost. Updates are made every 6 months or so, depending on requests.
