To collect information such as passwords, online criminals use "spoofing" to direct Internet users to fraudulent Web sites. In one study of Internet fraud, students were warned about spoofing and then asked to log in to their university account starting from the university's home page. In some cases, the login link led to the genuine dialog box. In others, the box looked genuine but in fact was linked to a different site that recorded the ID and password the student entered. The box that appeared for each student was determined at random. An alert student could detect the fraud by looking at the true Internet address displayed in the browser status bar, but most just entered their ID and password. Is this study an experiment? Why? What are the explanatory and response variables?

Step by step solution

01

Determine if it is an Experiment

An experiment deliberately imposes some treatment on individuals to measure their responses. In this study, the treatment is whether the students are shown a genuine login box or a fraudulent one, and this is assigned randomly. Thus, this study qualifies as an experiment.

02

Identify the Explanatory Variable

An explanatory variable is one that explains changes in a response variable. In this study, the explanatory variable is the type of login box shown to the student, whether it is genuine or fraudulent.

03

Identify the Response Variable

The response variable is the outcome of interest observed in the experiment. Here, the response variable is whether the student successfully detects the fraudulent login box or enters their ID and password, possibly compromising their credentials.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Explanatory Variable

In the realm of statistics experiments, the explanatory variable plays a critical role. It's the factor that is manipulated to observe its effect on other variables. In the Internet fraud study, the explanatory variable is the type of login box that students encountered—whether it was genuine or fraudulent. The researchers deliberately chose what type of login box each student would see, allowing them to examine how this manipulation influenced the students' actions. This variable acts as the "cause" in the cause-and-effect relationship we are trying to understand. By altering the explanatory variable, we get insights into how such changes influence the response variable.

Response Variable

The response variable, also known as the dependent variable, is what the researchers measure to see how it changes in response to alterations in the explanatory variable. In the context of the Internet fraud study, the response variable is whether students successfully detected the fraudulent login box versus simply entering their ID and password. Essentially, this variable reflects the "effect" in the cause-and-effect relationship. By observing changes in this variable, researchers can deduce insights into the level of student awareness about Internet fraud. It is crucial because it provides the data needed to measure the outcome of the experiment effectively.

Random Assignment

Random assignment is a cornerstone of true experimental designs in research. It involves randomly assigning participants to different groups to ensure that each group is the same before treatment is applied. This method eliminates biases that could affect the results, providing a clearer picture of the treatment’s effect. In the Internet fraud study, random assignment ensured that students were assigned at random to either a genuine or fraudulent login box. This randomness is crucial because it helps to ensure that any differences observed in the response variable are more likely due to the manipulation of the explanatory variable rather than some pre-existing differences among the participants.

Internet Fraud Awareness

Internet fraud awareness is increasingly important in our digital age. It refers to the public’s understanding and ability to recognize fraudulent activities online, such as spoofing, phishing, and other tactics used to steal personal information. In the study, the ability of students to detect a fraudulent login box was a direct measure of their Internet fraud awareness. This awareness is vital because it can protect users from falling victim to scams that could compromise their sensitive information. Education and training can significantly increase awareness, enabling users to stay safe online by recognizing the warning signs of fraudulent activities.
