Read through the following study description. Then, answer the questions below about this study. In this study, the effect of screen brightness on reading comprehension is explored. Participants are recruited from an undergraduate psychology class and are asked to read an article on a digital device under four different brightness settings: very low, low, medium, and high. The comprehension of the content is assessed through a quiz following each reading session. Each participant reads different articles of similar difficulty and length under each condition, though the specific articles are varied with different brightnesses. The study notes the age of participants and the type of device used (tablet or laptop) to monitor any potential influence on the results. 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?
