Question

A researcher decides is interested in investigating perceived leadership. The investigator brings groups of 12 students into a lab. The researcher randomly assigns the students into two groups of six and puts them into separate rooms. Group A is told that they will be performing a task in a competition with the other group. Group B is told they will be filling out a questionnaire shortly. The investigator then leaves them alone for 10 minutes, but records their behavior through a two-way mirror to see how many conversations each person initiates. At the end of the study, all participants vote by secret ballot for a leader from their group. The investigator follows the same procedure with 20 such groups and finds that those students who initiated more conversations received more votes as leader than those who initiated fewer conversations.

 

a)Did the investigator conduct an experiment or a correlational study? How can you tell? Your brief answer should focus on what is (are) the crucial methodological characteristic(s) that differentiate(s) the two types of investigations. (2 Points)

 

b)Identify the independent variable and dependent variable in the investigation you described in part a above. (2 Points)

 

c)Why does it matter which type of investigation it was in terms of the conclusions or interpretations that are (or are not) appropriate to draw and why? (Hint: think about the strength and weakness of the study design to answer this question). (2 Points)

 

 

 

Answer 1

A. The examiner directed exploratory research. Expr]erimental inquire about is a kind of study that endeavors to impact a specific variable (Dependant variable) with some controlled factors (Independent variable). in this technique, a scientist is anticipating making an ace arrangement that determining a strategy for gathering and breaking down the required data in an examination setting.

major methodological quality of exploratory research are;

1. manages 2 gatherings

2. The yield depends on perception, depiction, and expectation

while correlational methodological qualities are;

1. manages a solitary gathering

2. ends depend on factual out yield.

B. Subordinate variable: Perceived administration (Outcome)

Free Variable: 2-route discussions with individuals (Treatment)

C. The principle purposes for the choice of trial strategy are:

1. It has 2 gatherings

2. Irregular Assignments to the gathering

3. Gatherings get a treatment

4. Perception of the analyst on the treatment viability

Be that as it may, a similar plan has some shortcoming of:

Hard to control the gathering

Difficult to get co-activity from the part for the treatment

Moral issues identified with the person that repeat in considers.

Some human factors neither have substantial quantifiable models nor instruments to gauge.
