Reаd thrоugh the fоllоwing study description. Then, аnswer the questions below аbout this study. In this investigation, researchers examine how the color scheme of a website affects user engagement, measured by time spent on the site. Participants are recruited from an undergraduate psychology class and are shown the same website designed with two different color schemes: a high-contrast scheme (black text on white background) and a low-contrast scheme (gray text on a light gray background). Each participant experiences both versions of the website. During their interaction, the time each participant spends on the website is recorded. Additional factors such as the participant's age, gender, and prior experience with similar websites are also documented to assess their impact on engagement levels. What should this study's null and alternative hypotheses be? What are this study's dependent and independent variables? What are some control variables and random variables that might come up in this study as designed? What are some potential confounding variables that might come up in this study as designed? Is this study best characterized as within-subjects or between-subjects, and why? This description of the study does not describe how the study will account for order effects. Last, briefly define order effects, then briefly describe how you might add to this study to control for order effects.
