The ACT is a standardized test administered to high school students and used to determine college admissions. The test is offered approximately six times per school year, and students are allowed to take it up to 12 times. Students often take the test more than once, and 57% of students who completed a retake improved their score. The ACT can cost about $35–$55, but financial aid is available. Students are responsible for providing the list of colleges to which they would like to submit their scores. Some schools may help their students register for the test, but if they don't, students can register online. Students may not take the test without registering first. The ACT examines math and literacy skills with an optional writing section, and the best score a student can receive is 36. Not all colleges accept the ACT; it is the student's responsibility to find out which tests their prospective college requires.

What is most likely the reason a students' score would improve on a retake?

(adapted from m. m. duguid and j. a. goncalo, living large: the powerful overestimate their own height. ) in a study of power and self-image, participants were not told the true purpose of the study; instead, they believed they were participating in a business simulation. researchers randomly assigned participants to a high power(n = 44) or low-power (n = 44) condition. in the high-power condition, participants recalled a time when they had power over others, and in the low-power condition, they recalled a time when others had power over them. participants were asked to adjust the height (in centimeters) of an electronic graphical image (an avatar)of themselves to reflect their personal appearance. results indicated a statistically significant difference in participants’ perceptions of their own height across the two conditions. participants in the high-power condition created taller self-images (mean = 6.0, standard deviation = 1.5) than participants in the low-power condition(mean = 4.0, standard deviation = 1.0). * describe independent variable- describe how researchers measured the independent variable- explain why the researchers can conclude that there is a cause-and-effect relationship between the independent and dependent variables. - explain what statistical significance means in the context of the study.- explain why debriefing would be necessary in the study. -
