Turning Research Questions into HypothesesIn this exercise, you will practice creating hypotheses and operationalizing variables for research questions.Take the research questions below as a starting point. Develop hypotheses related to each research question. Once you have developed these hypotheses, operationalize each variable in your hypotheses. For example, consider the research question "How do hospital environments shape recovery times for patients?" You might write the hypothesis "Patients who have quieter hospital rooms will recover from abdominal surgery faster than those with noisy rooms." This hypothesis includes two variables: recovery time and loudness of hospital rooms. You might operationalize these variables by saying that recovery time is measured by counting the number
of days from when the abdominal surgery occurred until patients say that they are able to go back to their normal activities. And you might operationalize loudness of hospital rooms by using a sound level meter to measure the number of decibels of noise in the hospital room at six specific times throughout the day, perhaps 9 a.m., 1 p.m., 5 p.m., 9 p.m., 1 a.m., and 5 a.m.How does exposure to fast-food advertising affect teenagers' eating habits?
