- Discuss the difference between concurrent validity and predictive validity and describe a situation in which you would use an instrument that has concurrent validity and predictive validity.arrow_forwardA researcher is testing whether traffic tickets are given out equally to drivers driving different makes of car. The makes of car that he is including are: Volkswagon, Volvo, Mercedes, Ford, GMC, Chevrolet, and Tesla. So, the categorical (nominal) variable is make of car, and you should be able to determine c, the number of categories that exist on this variable. The researcher is doing this study by looking at the make of car for a sample of n=25 traffic tickets. Now assume the researcher wants to use alpha = .05. Given this alpha--and given the df which you should be able to figure out--what is the correct value for the χ2Critical?

- The first box options are "greater than" or "less than" . Second box is "reject" or "fail to reject" this is "is" or "is not". next sentence first box is "do not include" or "include" Second box is "equal" or "not equal" third box is only negative or positive&negative or only positive. Fourth box is the same or lower or higher.arrow_forwardSelect the correct statement. This student is arguing against school choice. Which statement best serves as the writer’s claim? School Choice: Good Intentions, Extremely Harmful Since the desegregation of schools in America, the question of school choice has been at the center of many heated debates. Some argue that charter schools or school choice programs put public schools at risk. Those people also argue that some neighborhood schools would suffer if kids had the freedom to commute to schools of their choice. Others argue that parents should control where their students learn, even if it means going to a school outside of their zoned area. However, school choice highlights problems with the inequities in the school system. All schools should provide students with quality education and school choice prevents that from happening.arrow_forwardA researcher observes that more acts of vandalism are committed by same-sexgangs than by mixed-sex gangs. She theorizes that competition for recognitionamong equal-status peers increases the tendency to commit publicly deviant acts.What type(s) of reasoning is this?A. inductive reasoningB. deductive reasoningC. neither inductive nor deductive reasoningD. both inductive and deductive reasoningarrow_forward
