rate model. Create a loader to refresh response rates for all
subcategories.
Use precalculated response rates in views
Wrap more elements in page caching
Calculate a response rate for a subcategory if one does not already
exist
Implement large speed improvements to score calculations. Add page caching to all pages. Small speed improvements to response rate by filtering out
survey items without responses with `none?` `method vs count == 0`.
average those groupings and the way up the framework. Likert scores for
a survey_item are averaged. Then all the survey_items in a scale are
averaged. Then student scales in a measure are averaged. And teacher
scales in a measure are averaged. Then the average of those two
calculations becomes the score for a measure. Then the measures in a
subcategory are averaged.
