Once every two weeks.
All assignments, including the mid-term test, are to be done at home, in groups of three or less. Each group of students should turn in a single copy of the group homework or mid-term test with all names listed; all group members will receive the same grade. The final exam is individual. You can use books, calculators or computers. The homework will contain tasks and questions that will require you to use a statistical computer program. All assignments must be submitted electronically by the beginning of class, two weeks after they were distributed.
