单选题Students: Pass or Fail When students who are taking a course for regular grades are compared with students who are taking the same course on a pass-fail basis, the graded students achieved higher grades. The comparison is made possible by not telling the instructor which students are taking the course on the pass-fail basis and having him or her assign letter grades to all students. The registrar converts these to pass-fail for those students who had previously elected this option. This provision is included to protect the pass-fail students from possible instructor bias. The data clearly show that there is a difference in grades between the two groups of students in the same class, those electing to take the course for pass-fail and those taking the course for regular letter grades. The interpretations of this difference, however, vary widely. Some claim that this difference proves that pass-fail students simply don"t work as hard or take the course seriously as students taking the course for letter grades. Other claim that this difference proves that only the less competent students elect the pass-fail option. Others claim that this difference proves that students only take their most difficult (for them) courses under the pass-fail option and therefore are exploring areas they might otherwise attempt to avoid. Others claim that this difference proves that students use the pass-fail option only in courses where the teacher is so personally uninspiring as to need the threat of letter grades in order to goad the students into studying. What, in fact, do the data really prove? Nothing, other than that a difference in grades does indeed exit between the two groups. All the previously mentioned explanations are only hypotheses, that is, guesses about the possible reason for the difference. One or even several of these hypotheses might eventually be proved valid, but at present none of the studies really proves any of the hypotheses. Yet, in the hands of a statistical charlatan, the data may seem to an unsophisticated audience to prove whatever he or she says they prove. The most common error in reading and interpreting research studies is assuming that a casual factor has been isolated when, in fact, it has not. As will be seen, most studies in the field of educational psychology do not allow for a cause-and-effect interpretation, and yet it is extremely tempting them as though they did. This is probably the major booby trap awaiting the unwary student. Just because two variables are associated doesn"t necessarily mean that one is the cause of the other.

单选题 Nine states and the District of Columbia are doing away with the sales tax on items such as clothes, shoes and even notebooks over the next few weeks, just in time for back-to- school shopping. Most of the promotions last only a few days, so shoppers will have to act quickly to get a tax break. The tax holidays, which have already expired in two other states, apply to small and large items. For example, the tax break applies to any school supply that costs $15 or less in New Mexico. In Massachusetts, it covers most retail purchases of $2,500 or less. Stores may offer additional savings because these events "give retailers an opportunity to have a sale on top of what the state is doing," says Verenda Smith, government affairs associate at the Federation of Tax Administrators. No industry-wide figures are available about how much consumers save annually from these tax breaks. But Texas estimates that shoppers will save $47.4 million in taxes this year, nearly a 3 percent increase from the previous year. Massachusetts says shoppers saved roughly $10 million in taxes during its 2005 event. States that cast aside these promotions when a slow economy pinched state budgets are now reviving them in hopes of stimulating local economies. Some states also believe the gain in {{U}}consumer goodwill{{/U}} helps balance out the loss in tax revenue. In some cases, tax losses are minimal because serious shoppers don't stop at clothes and books. "While states give up sales tax, they usually break even on sales-tax collection," says J. Craig Shearman, a vice-president at the National Retail Federation. Sophie Beckmann, a certified public accountant at A. G. Edwards in St. Louis, says she'll avoid that temptation by making a list of necessities. On the Missouri resident's shopping list: notebooks, pencils, glue and three or four outfits for her son, who is entering the fifth grade this month. She plans to pocket any tax savings. "When you start buying more and spending more just because of the savings, then you're not doing yourself a favor," Beckmann says.
