SBAC: Data but no meaning, when meaning matters most

“Statistical calculations based on warped figures lead to confusion, frustration and wrong decisions.” These wise words from W. Edwards Deming are most timely as the educational community awaits the next batch of big data to be delivered, the results of the latest test promising to revolutionize schooling, the SBAC. A hollow promise, based on warped figures, that will certainly deliver hollow results. What will the SBAC data mean? Nothing. Absolutely nothing at all. Numbers in isolation, lacking story and context.
