Question 47 Researchers hypothesize that experiencing a certain scent while viewing paintings of flowers will influence the viewers' ratings of attractiveness of the paintings. Researchers dispensed a floral scent in one room with paintings and no scent in another room with paintings. Which statement is accurate regarding the study? A. The study's design is an observational study since viewers were observing paintings and noting their ratings. B. The independent variable is the presence or absence of scent in the rooms. C. The dependent variable is the amount of time viewers spent observing paintings. D. Informing viewers ahead of time whether a scent was absent or present in the room is important for accurate ratings.

Step 1
- The study involves manipulating a variable (presence or absence of scent) to observe its effect on another variable (ratings of attractiveness). This indicates an experimental study, not an observational study. - Therefore, option A is incorrect. Show more…

Researchers believed that floral scent can sometimes improve a person's learning ability. They set up an experiment in which each of 22 subjects completed sets of pencil-and-paper mazes. Each subject wore a floral-scented mask and an unscented mask, in random order. The researchers measured the time to complete the sets of mazes. (Questions 1, 2, 3) What is the explanatory variable? a) The amount of scent. b) The presence or absence of floral scent. c) The time to complete the mazes. d) Whether the subject was able to complete the mazes quicker while wearing a floral-scented mask. What is the response variable? a) The amount of scent. b) The presence or absence of the floral scent. c) The time to complete the mazes. d) Whether the subject was able to complete the mazes quicker while wearing a floral-scented mask. The researchers controlled influences of lurking variables by: a) Giving each subject a floral-scented mask and an unscented mask. b) Randomly assigning half of the subjects to wear a floral-scented mask only and the other half to wear an unscented mask only. c) Giving each subject two sets of mazes.

Determine whether the study depicts an observational study or an experiment. Third-grade students are randomly divided into two groups. One group is taught English using traditional techniques. The other is taught English using a reform method. After 1 year, each group is given an achievement test to compare its proficiency with that of the other group. Choose the correct description of the study. A. The study is an observational study because the researchers control one variable to determine the effect on the response variable. B. The study is an experiment because the researchers control one variable to determine the effect on the response variable. C. The study is an experiment because the study examines individuals in a sample, but does not try to influence the variable of interest. D. The study is an observational study because the study examines individuals in a sample, but does not try to influence the response variable. Click to select your answer.
A study $^{60}$ examined the impact of the color red on how attractive men perceive women to be. In the study, men were randomly divided into two groups and were asked to rate the attractiveness of women on a scale of 1 (not at all attractive) to 9 (extremely attractive). One group of men were shown pictures of women on a white background and the other group were shown the same pictures of women on a red background. The men who saw women on the red background rated them as more attractive. All participants and those showing the pictures and collecting the data were not aware of the purpose of the study. (a) Is this an experiment or an observational study? Explain. (b) What is the explanatory variable and what is the response variable? Identify each as categorical or quantitative. (c) How was randomization used in this experiment? How was blinding used? (d) Can we conclude that using a red background color instead of white increases men's attractiveness rating of women's pictures?
