<h3><u>Cross-sectional research: what is it?</u></h3>
A cross-sectional study is a sort of observational research that examines data of variables gathered at one specific point in time across a sample population or a pre-defined subgroup.
Transverse analysis, cross-sectional analysis, and prevalence studies are other names for this sort of research. Even though it doesn't entail running experiments, cross-sectional research is frequently used by academics to understand outcomes in the physical and social sciences as well as many business domains.
<h3><u>Cross-sectional study characteristics.</u></h3>
A cross-sectional study must have, among other things:
- With the same set of data over a predetermined time frame, researchers can conduct a cross-sectional study.
- While similar studies could focus on the same variable of interest, each one looks at a different group of people.
- Contrary to longitudinal investigations, where variables can vary over the course of extended research, the cross-sectional analysis evaluates themes during a single instance with a fixed start and stopping point.
- In cross-sectional studies, one independent variable and one or more dependent variables can both be examined.

Answer:
Option D,shows the amount of real output that will be purchased at each possible price level, is the right answer.
Explanation:
In the context of macroeconomics, the emphasis is on the demand and the supply of all the goods and services produced in and by an economy. Since the focus is on all demand and all supply, the very phenomena of demand and supply are known as the aggregate demand and aggregate supply.
The visual representation of aggregate demand (demand for the total quantity of all the goods and services demanded by the people of an economy at varying prices) is known as the Aggregate demand curve. Accordingly, an aggregate demand curve is the means of representing the amount of real output that will be bought at each potential price level.
