Answer 1

Answer:

Standardized variable

Explanation:

Standardized variable: In research methods, the term "standardized variable" is also referred to as "standard score" or "z-score" and is described as one of the different variables that have been "re-scaled" to possess a standard deviation of 1 and a mean of 0. Moreover, these variables tend to contain different students score on a specific test related to the wisdom of social studies, mathematics, and science. However, teachers and authors generally use a standardized variable in contrast with control variables and it is supposed to be "constant" in specific research or an experiment.

In the question above, the given statement represents the "standardized variable".

hope this helps!!:)

Answer 2

The standardized variable is one with a mean of zero and a standard deviation of one, and the further discussion can be defined as follows:

Standardized Variable:

• It is also known as the "standard score" or "z-score" in research methodologies.
• It refers to one of the various variables that have been "re-scaled" to get a standard deviation of 1 and a mean of 0.
• Furthermore, the various kids' scores on a certain test connected to the wisdom of social studies, mathematics, and science are often included in these factors.
• In contrast, to control variables, teachers and authors typically use a standard variable, which is intended to be "constant" in certain research or experiments.
