Check Your Assumptions

Always check your assumptions when interpreting data and data visualizations. That's the take away from this exercise. Class members examine a failed project that looks at search trends to predict flu outbreaks and consider the assumptions that caused the failure. They then look at the digital divide and the assumptions made about data collected online. Finally, pupils explain why assumptions may lead to incorrect conclusions about data.
