Grace randomly assigns college-bound African-American students to the intervention or to a control condition.  Grace gives a mathematics achievement test in September to both groups.  Through the academic year the treatment condition receives the intervention.  She uses end of year achievement tests to see whether there are differences between conditions. Grace found that students studied together for the end of year achievement tests.  She believes that some of the students in the treatment condition shared intervention information with the control group.  Which of the following threats does Grace now have to be most concerned about?
◦ Selection by treatment
◦ Maturation by treatment
◦ Statistical regression
◦ Treatment diffusion

These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
