Cross-sectional data:- These are the observations that are made at the same point in the defined time period. These observations could be on a single day or these observations can also be for a week, month, year.
So the case provided to us is the data for a season of NFL that was from 2011-2012 season.So we can say that the data is cross-sectional.
Option (a) is true that the computers have become smaller and smaller with advancement of the technology. The earlier version of computers used vacuum tubes and are very big in size.
As the years passed and due to the advancement of the transistors the computers have become smaller in size.
Option (b) is true. With the advancement in the research in circuits used in the computer like Integrated Circuits the computers have become faster.
The response time of the operating system has reduced drastically.
Option (c) is wrong option. The computers have become cheaper. The transistors are cheaper compared to the vacuum tubes which are used in the earlier computers.
The price of the same computer (memory and time efficiency) has become less in the coming years than in the previous years with the advancement in the research of transistors.
Option (d) is true. Now-a-days computers support more and more number of applications. Computers has more number of applications in various and diversified fields.
With the advancements in the computers, the computers are finding more applications in different fields like medicine, law, transport industries etc.
