When a group is small, each family has a large effect on its results. With 4 responses, one family’s answer moves that group’s percentage by 25 points. With 30 responses, one family moves it by about 3 points.

That is why Lesson 2 set a minimum reporting threshold of 5 responses. Below that, results are too unstable to report and can identify families. Treat results from small groups as a prompt for conversation, not a conclusion, and combine them into a larger group or report them center-wide.
