Data Interrogations for Critical Statistical Literacy
By Susan O. Cannon, Mercer University The classroom was unusually quiet, especially for a middle school. The only sound was that of pencils rushing across paper as students looked back and forth from the image projected on the screen to their papers. The image showed a refugee camp. Tents with the United Nations emblem stretched out in the background, and two women and three … [Read more...] about Data Interrogations for Critical Statistical Literacy
