The aim of the Perestroika in the Soviet Union was to make the Socialism system there more efficient, so that the goods produced are actually the ones needed (but it ended up changing the system altogether)<span />
Independent variable
To achieve internal validity, a researcher must design and conduct experiments where only the independent variable can be the cause of the results.
<h3>What are internal and external validity?</h3>
The degree to which a study shows a reliable cause-and-effect relationship between a therapy and a result is known as internal validity. Internal validity also shows that a particular investigation enables the exclusion of competing hypotheses for a finding. Internal validity is not a binary term, either yes or no. Instead, we evaluate how confident we can be in a study's conclusions depending on whether it avoids pitfalls that could cast doubt on the results.
The term external validity describes how effectively the results of a study should be extrapolated to other contexts. In other words, the generalizability of the results is the subject of this form of validity. For instance, are the results generalizable to different populations, environments, circumstances, and eras? Transferability is a different word that describes external validity and a qualitative research design. Whether results apply other circumstances with similar characteristics is referred to as transferability.

Answer:
The given statement is true.
Explanation:
Economics is defined as the science of utilization of scarce resources so that the collective needs of the society are fulfilled to the most extent resulting in the most efficient use of the resources.
Since in the world many resources are limited thus we need to use them in the most efficient way so that all the collective needs of the society are fulfilled so that each individual of the society gets his/her fair share of the resources and thus society progresses as a whole with the utilization of these resources.
In advance economic studies economics can be differentiated into macroeconomics and microeconomics each have their individual roles in understanding transfer of goods and services.
