Final answer:
The Kinsey research collected sexual behavior data via interviews and developed the Kinsey scale, while Masters and Johnson measured physiological variables during sexual activities.
Step-by-step explanation:
One main way in which the Kinsey research differed from the Masters and Johnson research is that Kinsey collected data through personal interviews, whereas Masters and Johnson recorded measurements of physiological variables during sexual acts. Kinsey's method involved extensive interviews to uncover a diverse range of sexual behaviors and conceptualized sexuality as a continuum, famously creating the Kinsey scale. On the other hand, Masters and Johnson conducted observational studies, measuring physiological responses like blood pressure, respiration rate, and sexual arousal indicators during intercourse and mastur-bation.
