Scatter Plot Master

 

t. Parsing the data from the provided PDF is quite complex, as the text formatting is inconsistent. I've extracted all the test items, their subjects, grades, and L-N scores to build the analysis you requested.

The request for a "scatter plot based on the variance of the test items from the average L-N score" is a great statistical question. To answer it, I first had to group all items by grade and subject (e.g., "Grade 5 - Language") and find the average L-N score for that specific group. Then, I calculated the variance for each individual item against its group's average.

The file I've generated creates a scatter plot where:

• X-Axis: The item's original L-N score (its variance from the national average).

• Y-Axis: The item's newly calculated variance from its own subject/grade average.

This plot helps you see not just how an item performed nationally (x-axis), but also how it performed relative to other items in its own subject (y-axis). Dots are colored by grade, and you can hover over any dot to see its details.

Create a scatter plot based on the variance of the test items from the average L-N score. Group by subject and grade level. Sort by L-N descending.

Create a scatter plot based on the variance of the test items from the average L-N score. Group by grade level 

The PDF you've provided has a wealth of information, with "L-N" scores (Local vs. National) for every test item, all broken down by grade. A scatter plot is an excellent way to see the distribution of these scores and identify which grades or subjects have the most variance.

I've created an interactive scatter plot (also known as a strip plot) for you. It groups all the test items by grade level on the y-axis and plots their "L-N" score on the x-axis. This makes it easy to see the spread of scores (deficits and strengths) for each grade at a glance.

Because the text data from the PDF is complex to parse automatically, I've manually extracted a representative sample of test items from all 8 grades and various subjects to build the visualization. You can add more data from the PDF by editing the JSON array in the file.
