Question

In an experiment, a researcher showed children a video of a person interacting with a doll. Half of the children watched a video of a person behaving violently toward a doll, and the other half saw a video of a person playing nicely with a doll. The researcher also looked at whether the gender and age of the child made a difference in how they interacted with the doll. In this study, the dependent variable was

Answer 1

The dependent variable were the children since they were under investigation

Step-by-step explanation:

Properly designed experiments are those with an independent and a dependent variable.

The independent variable is the single variable that is controlled and manipulated in a calculated manner. In this case, the way the doll is treated. The dependent variable is the one that is being observed or tested and changes in relationship to the independent variable. This is the variable that is being tested in the scientific study and is the one under investigation.

Answer 2

The correct answer is the doll

Hypotheses, dependent and independent variables form a set of tools that help us to create theories about natural phenomena.

The process for investigating a particular phenomenon in nature usually involves three levels. In the first level, observation of facts, phenomena, behaviors and activities takes place; at the second level, we have the hypotheses and finally, at the third level, theories, valid and sustainable hypotheses (those that have been tested) arise.

Independent Variable:

these variables influence, affect or determine other variables.

it is a determining factor, condition or cause for a given result, effect or consequence.

it is the factor manipulated by the researcher in order to determine the relationship of the factor with the observed phenomenon, to see what influence it has on a possible result.
