The data collected in the study would likely be quantitative, specifically continuous data, as it involves measuring the amount of alcohol consumed per week. This type of data provides a numerical measurement that can be further analyzed statistically to draw conclusions about participants' drinking habits.
Participants in the original obedience study conducted by Stanley Milgram were led to believe that the study was about the effects of punishment on learning and memory. They were told that the study was investigating the role of punishment in improving memory retention.
Confounding variable.
Longitudinal research is used to study behavior of study participants over time as they age. This method involves collecting data from the same individuals at different points in their lives to observe changes and developmental patterns.
This type of study is known as a double-blind study. It helps to minimize bias by ensuring that neither the experimenter nor the participants can influence the results based on their expectations or knowledge of who is in each group.
A double-blind experiment is one where both the participants and the researchers are unaware of who belongs to the experimental or control group until after the study is completed. This helps eliminate bias in the results by ensuring that neither the participants' nor researchers' expectations influence the outcome.

An intensive investigation of one or more participants involves a thorough examination of their behavior, thoughts, emotions, and interactions within a specific context or setting. This process typically utilizes various research methods such as observations, interviews, surveys, and experiments to gather in-depth data and insights about the participants. It aims to uncover patterns, understand motivations, and gain a comprehensive understanding of the individual or group under study.
The phenomenon is called the Hawthorne effect. It occurs when individuals modify their behavior or performance in response to being observed as part of a study, regardless of the actual intervention being studied.

The exact figure varies from study to study, but the generally accepted number is that over 70 percent of US teens have tried alcohol at least once. Around 30% of US teens have binge drank or drink daily.
The article also states that study participants already had severe heart disease and in one study, 36% of the participants smoked.
quasi-experimental study
When the nature of a research study is kept from the subject, it is known as deception. This can be done to prevent participants from altering their behavior, which could impact the validity of the study's findings. However, researchers must follow ethical guidelines and debrief participants after the study to ensure they understand the true nature of the research.
