Correct Option: B

This benefit has perhaps been overstated, however; unless you're building a simulator of a real-world process, such ......... 'real-world' objects form just the surface of your system.

  1. profligate

  2. spectral

  3. surrogate

  4. virtual

Correct Option: C

The complexity of your design lies underneath that surface, in code that reflects business rules, resource allocation, algorithms, and other computer science concerns; if you only use objects to reflect the real world, you leave yourself with a lot of work.

  2. leave

  3. fool

  4. set

Correct Option: B

Coupling refers to the ways in which and degrees to which one part of the system relies on the details of another part: the tighter the coupling, the more changes in one part of the system will ......... throughout the system, while with loose coupling, the interfaces between subsystems are well defined and restricted.

  1. leak

  2. ripple

  3. seep

  4. wander

Correct Option: B

......... refers to the degree in which elements within a subsystem form a single, unified concept, with no excess elements: where it is strong, there is easier comprehension and thus more reliable code.

  1. True

  2. False

If you want to analyze mean value of the numeric variable Salary based on gender of a given organization then you will keep:

  1. Analysis Variable: Salary; Classification variable: Gender; Statistics: Mean

  2. Analysis Variable: Gender; Classification variable: Salary; Statistics: Mean

  3. Analysis Variable: Salary; Classification variable: Mean; Statistics: Salary

  4. Analysis Variable: Mean; Classification variable: Salary; Statistics: Mean

Correct Option: A

Which one of the following is NOT the default statistical measures calculated by Proc Means:

  1. N

  2. MEAN

  3. STD
