To assess the effect that chocolate may have on attitude over time, a researcher recruits a group of participants to complete the Acme Attitude Survey (AAS), which renders a 0 to 100 score (0 = Very bad attitude . . . 100 = Very good attitude). After giving the pretest, the researcher gives each participant a large bar of chocolate. The researcher read-ministers the AAS three more times: 5 minutes after the participant eats the chocolate, 1 hour later, and 4 hours later.

The Zzzleep Zzzound app provides audio selections (e.g., gentle rain, ocean waves, soothing music) to help induce peaceful sleep. During the night, the app uses the camera and motion sensor to gather sleep data. If the user wakes during the night, the app senses it and plays the selected sound for 10 minutes. For the first week, the app runs without any audio to gather baseline data. Once a week, the software transmits the mean sleep time per night for that week to the sleep researcher’s database.

A political consultant convened a focus group to evaluate the effectiveness of two commercials promoting a candidate. Prior to running any media, the participants are asked to answer one question: Do you intend to vote for Jones in the upcoming election? The participants will respond using a scale ranging from 1 to 7 (1 = Absolutely will not vote for Jones . . . 7 = Absolutely will vote for Jones). Next, the facilitator runs a 30-second radio advertisement, promoting the candidate, after which, the participants are asked to respond to the same question using the 1 to 7 scale. Finally, the facilitator runs a 30-second video advertisement for the candidate, after which, the participants will respond to the voting intentions using the 1 to 7 scale.

On Tuesday morning, the student council at a middle school announced its plan to combat the chronic litter problem in the outdoor lunch area: The 16 large trash cans in the lunch area now each have the name of a popular band on them—they are now referred to as Band-Cans. The Band-Can containing the most trash at the end of each day wins; music from that band’s latest release will be played on the school’s public address system in between classes for the next day. The Band-Cans are 42 inches tall; at the end of each day, starting on Monday (to gather baseline data), the members of the student council will use a tape measure to record how full each Band-Can is (0 = Empty . . . 42 = Full).

Acme Industries has implemented a new website for employees to enter their weekly hours (e.g., start time, end time, sick hours, vacation hours, holiday hours, family leave hours). Upon clicking Save, the system checks the validity of the entries and points the user to correct any errors or omissions before saving the data. To evaluate the efficiency of this new website, the system journals the access time (in seconds) indicating how long it took for each employee to file their daily entries. A manager will assess the mean access times starting at the initial launch of the website (Week1) and continue to gather data for an additional 2 weeks (Week2 and Week3).

The Zzzleep Zzzound app provides audio selections (e.g., gentle rain, ocean waves, soothing music) to help induce peaceful sleep. During the night, the app uses the camera and motion sensor to gather sleep data. If the user wakes during the night, the app senses it and plays the selected sound for 10 minutes. For the first week, the app runs without any audio to gather baseline data. Once a week, the software transmits the mean sleep time per night for that week to the sleep researcher’s database.

On Tuesday morning, the student council at a middle school announced its plan to combat the chronic litter problem in the outdoor lunch area: The 16 large trash cans in the lunch area now each have the name of a popular band on them—they are now referred to as Band-Cans. The Band-Can containing the most trash at the end of each day wins; music from that band’s latest release will be played on the school’s public address system in between classes for the next day. The Band-Cans are 42 inches tall; at the end of each day, starting on Monday (to gather baseline data), the members of the student council will use a tape measure to record how full each Band-Can is (0 = Empty . . . 42 = Full).

Acme Industries has implemented a new website for employees to enter their weekly hours (e.g., start time, end time, sick hours, vacation hours, holiday hours, family leave hours). Upon clicking Save, the system checks the validity of the entries and points the user to correct any errors or omissions before saving the data. To evaluate the efficiency of this new website, the system journals the access time (in seconds) indicating how long it took for each employee to file their daily entries. A manager will assess the mean access times starting at the initial launch of the website (Week1), and continue to gather data for the next week (Week2).

The Acme Veterinary Nutrition Laboratory wants to find out if its three dog foods appeal to all dogs equally or if breed is a factor in a dog’s food preference. Per the research criteria specified, you recruit 90 pets: 30 cocker spaniels, 30 beagles, and 30 keeshonds. Owners are asked not to feed their pets for 4 hours prior to the test. Each dog is tested individually; the dog is placed 5 feet (1.5 meters) away from three clear bowls of dog food, all with equal weights. On cue, the leash is removed, and the dog is free to eat from any bowl(s). After dismissing each participant, you weigh the bowls; the lightest bowl wins (meaning that the dog ate the most food from that bowl). In case of a tie, the winning bowl is the one that the dog went to first.

An exercise advocate wants to determine the effect that walking rigorously has on weight loss. The researcher recruits participants to engage in a weeklong study. The researcher instructs participants to take a brisk walk as many days of the week as possible for as long as they can. Participants will record the following data: weight prior to engaging in the walking regimen, the amount of time walked each day, and their weight at the end of the week. Participants will submit their data to the researcher at the end of the week. The researcher will preprocess the data to derive the total number of hours walked (WalkHrs) and the change in weight for each participant (WtLoss = weight at the end of the week − weight at the beginning of the week).

A social scientist has noticed that people seem to be spending a lot of nonwork hours on computers and wants to determine if this may, in some way, be associated with social relationship satisfaction (satisfaction derived from interacting with others). To determine if there is a correlation between nonwork computer hours and social satisfaction, the scientist recruited a group of participants and asked them to indicate (about) how many nonwork hours they spend on the computer each week. Next, each participant was given the Acme Social Satisfaction Inventory (ASSI); this self-administered instrument renders a score between 0 and 80 (0 = very low social satisfaction . . . 80 = very high social satisfaction).

A sociologist has learned from a prior study that there is a strong positive correlation between time spent playing a video game and the score the player earns on that game (practice makes perfect). Because achieving such proficiency is time-consuming, this sociologist expects that there may be a (negative) correlation between game score and overall academic performance (grade: 0 . . . 100). To determine if there is such an inverse correlation, the sociologist recruits a group of participants to play a popular video game for 15 minutes, at which time the researcher records the score.
