The issue is not that it's done incorrectly, the issue is that the limitations of the available sample are such that there will be a bias introduced. Most parents did not respond to request to be evaluated ! that's a very strong indication of a possible bias
- baldfat 11y agoIt states that the raw values come from the school database with a sample size of around 3,000 children. Also the teachers were giving the responses at the end of the school year. The parents did have to sign a letter at some point to be apart of this but it appears that there is an issue with the outcomes. I fully believe what is happening in my Head Start really is making a difference, but it seems to be harder to see the advantages right now with this research paper.

- baldfat 11y agoThank you. This study has rocked a lot of people in Head Start around the nation. This could cause problems with funding in the years ahead.
