I'm so proud of my students.
We just had a project finish where they had to inject bias into a survey and see if it affected results. For instance--does adding extra information to a question make people answer differently than they would have? How do characteristics of the interviewer affect results? Can you ask a question two different ways that are logically equivalent but would inspire different answers? Do people answer questions differently when it isn't anonymous?
The kids, for the most part, did some great work. I am way impressed with how controversial they were willing to be, with what they did for their posters, with the displays that they did... they really set the bar high for next year's kids.
Next year's kids.
