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

  1. N

  2. MEAN

  3. STD

  4. SUM


Correct Option: D

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

While using the WEIGHT option in Proc Means,If a WEIGHT variable value is missing, then PROC MEANS excludes the observation from the analysis.TRUE or FALSE?

  1. True

  2. False


Correct Option: B

Which of the following SQL functions can operate on any datatype?

  1. MAX

  2. TO_CHAR

  3. LOWER

  4. CEIL


Correct Option: A

Which character function can be used to return a specified portion of a character string?

  1. SUBSTR

  2. INSTR

  3. SUBSTRING

  4. POS


Correct Option: A

Which command will delete all data from a table and will not write to the rollback segment?

  1. DROP

  2. TRUNCATE

  3. DELETE

  4. CASCADE


Correct Option: B

Which Oracle access method is the fastest way for Oracle to retrieve a single row?

  1. Full table scan

  2. Table access by ROWID

  3. Access via unique index

  4. Primary key access


Correct Option: B

How many columns are presented after executing the below query:SELECT name||','||age||','||address "emp_details" FROM employee;

  1. 1

  2. 2

  3. 3

  4. 0


Correct Option: A

It seems that every new OO language author ......... the need to distinguish their language by coming up with new terminology.

  1. feels

  2. gets

  3. senses

  4. urges


Correct Option: A

Some Object-Oriented languages are less rigid than others in how much they require you to design around objects, but OO languages certainly support these quality ......... if you take the time to pursue them.

  1. contributions

  2. tribulations

  3. attributes

  4. tributes


Correct Option: C

......... 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. Adaptation

  2. Adherence

  3. Cohabitation

  4. Cohesion


Correct Option: D

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

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.

  1. bilk

  2. leave

  3. fool

  4. set


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

This mapping between objects in the real world and more abstract code objects encourages programmers to think in the problem domain, rather than in computer science terms.

  1. obtuse

  2. abstract

  3. abstruse

  4. oblique


Correct Option: B

One reason why objects are a powerful programming technique — the reason most often ......... in the early literature on Object-Oriented Programming — is that programmatic objects map naturally to real world objects.

  1. flouted

  2. routed

  3. scouted

  4. touted


Correct Option: D

In these Object-Oriented languages — C, C#, Java, Eiffel, Smalltalk, Visual Basic.NET, Perl, and many others programmers create classes, each of which defines the behavior and structure of a number of similar objects; then they write code that creates and manipulates objects that are instances of those classes.

  1. generates

  2. articulates

  3. manipulates

  4. eradicates


Correct Option: C

Many modern programming languages depend largely or exclusively on the concept of objects: a close ......... binding of data to the operations that can be performed upon that data.

  1. automatic

  2. enigmatic

  3. pragmatic

  4. syntactic


Correct Option: D

SAS DATES and TIME variables are numeric variables.

  1. True

  2. False


Correct Option: A

INFORMATS are used in SAS for

  1. To instruct SAS to read in values.

  2. instruct SAS to drop the variables.

  3. instructs SAS to write the values of the variable.

  4. To provide value for the variables.


Correct Option: A
