maria [59]

Answer:

Systematically describe; assess relations between variable. Option A

Explanation:

First, we will fill in the gap in the question, check below;

''Whereas observational research is designed to SYSTEMATICALLY DESCRIBE behavior, correlational research is designed to ASSESS RELATIONS BETWEEN VARIABLE''.

In order to analyze a particular subject there is a part of research techniques to be used in which the analyst just have to observe, the research method or technique for that is called the Observational research. The person observing or the analyst can also be a participant that is part of the subject and still observe.

When you take two things -- variables and you compare and contrast them, you are already using the Correlation research method.

An experiment was conducted to determine how the diameter of a wooden dowel would affect the depth that the dowel would penetrat
strojnjashka [21]

Answer:

Independent variable: The diameter of the wooden pins.

Dependent variable: The depth of the pins in the sand.

Control variable: height of 15 cm at which the pins will be thrown, boxes containing 30 kg of sand and weights of 80 grams.

Explanation:

An independent variable is one that does not need the influence of another variable to happen and that, its variation, influences that a measurable result occurs. In this case, as we know that the depth of the wooden pins is measured according to the influence of the diameter of these pins, we can say that the diameter of the wooden pins is the independent variable.

The dependent variable, on the other hand, is one that shows a measurable result through the influence of the independent variable. In this case, we can say that the depth of the wooden pins in the sand is the independent variable.

The control variable, in turn, is the factor that establishes an egalitarian environment in which the research will be established. In this case, the control variable is the height of 15 cm at which the pins will be thrown, the boxes containing 30kg of sand and the weights of 80 grams.
