What is the difference between the unchecked data and checked data?
The unchecked database reflects the results exactly as participants have entered them. As soon as you submit your results, they will automatically be available in this database. The project leader will periodically check this database and contact schools whose data appears to be in question. Only data that has been checked and verified by the project leader will be posted in the checked database. This is to ensure that when students analyze the data, they will not be mislead by any unreasonable, unverified, or incorrect data. The checked data will be available for viewing and downloading near the conclusion of the project. Please see the project schedule for details.
