When Krantz devised the experiment that produced the data in Table 3.1, he was interested in seeing whether the required degree of mental rotation influenced reaction time. From the answer to Exercise 3.14, what would you conclude about this question?

Exercise 3.14

In Table 3.1 the reaction-time data are broken down by the degrees of rotation separating the objects. (You may want to sort the data by this variable.) Use SPSS or another computer program to plot separate histograms of these data as a function of the Angle of rotation. (You can do it in R, but it requires things you don’t yet know. See the Web page for this chapter.) These data are available at https://www.uvm.edu/~dhowell/fundamentals9/DataFiles/MentalRotation.dat
