Truly Confounding Data
Can somebody help me? I can’t make heads or tails of this little bar graph I put together. It’s obvious that we have an unfortunate concentration of Bad Teachers in Wards 7 and 8. That’s the big story here, but is there anything else?
Note on the data: School data is average combined proficiency in reading and math for all traditional public schools in each ward of the city (no charters) on the DC CAS, our ‘state’ NCLB test. This average combines elementary and secondary schools and does not weight for size of student body. Poverty data is the average percent of children living in poverty in each ward from 2005-2009.
