Question 1

A ____, such as Microsoft Outlook or Lotus Organizer, can help manage meetings, interviews, appointments, and deadlines and provide a personal calendar and a to-do list, with priorities and the capability to check off completed items.
A) PIM
B) laptop
C) PDA
D) Visio

Accepted Answer

PIM stands for Personal Information Manager, which is a software program designed to help manage personal information such as the ones mentioned in the question. The other options (laptop, PDA, Visio) may have some productivity features, but they are not specifically designed to manage personal information in the same way a PIM is.

Question 2

In an interview, ____ limit or restrict the response.
A) open-ended questions
B) closed-ended questions
C) leading questions
D) range-of-response questions

Accepted Answer

Closed-ended questions limit or restrict the response because they typically require a yes or no answer, or a specific response from a list of options. Open-ended questions allow for more detailed and free-form responses, while leading questions may steer the interviewee in a certain direction or biased response. Range-of-response questions provide a range of options for the interviewee to choose from, but still do not allow for as much free-form response as open-ended questions.

Question 3

When preparing a representative sample from a list of 200 customers who complained about errors in their statements, a ____ might select every tenth customer for review.
A) systematic sample
B) stratified sample
C) random sample
D) comprehensive sample

Accepted Answer

A systematic sample is a type of probability sampling where every nth item in the population is selected for inclusion in the sample. In this case, every tenth customer is selected, making it a systematic sample. Stratified sampling involves dividing the population into subgroups and then randomly selecting from each subgroup, random sampling involves selecting individuals randomly without any specific pattern, and comprehensive sampling involves examining every single item in the population. None of these options apply in this scenario, making systematic sampling the best choice.

Question 4

When preparing a representative sample from a list of 200 customers who complained about errors in their statements, a ____ might select any 20 customers.
A) systematic sample
B) stratified sample
C) random sample
D) comprehensive sample

Accepted Answer

A random sample involves selecting respondents randomly from the population. In this case, selecting any 20 customers from the list of 200 complaints would be a random selection. A systematic sample involves selecting every nth customer, a stratified sample involves dividing the list of customers into subgroups based on some characteristic and selecting from each subgroup, and a comprehensive sample involves including every member of the population in the sample. None of these methods are necessary or appropriate for this particular situation.

Question 5

In an interview, ____ encourage spontaneous and unstructured responses.
A) open-ended questions
B) closed-ended questions
C) leading questions
D) range-of-response questions

Accepted Answer

Open-ended questions allow for more free-form and open-ended answers, whereas closed-ended questions typically have a limited set of predetermined responses. Leading questions can influence or trigger a certain response, and range-of-response questions are more about measuring the breadth of responses rather than the spontaneity of them.

Question 6

Question 7

In addition to direct costs, systems developers must identify and document indirect expenses that contribute to the ____.
A) TCO
B) REJ
C) FDD
D) UML

Accepted Answer

TCO stands for Total Cost of Ownership, which includes both direct and indirect expenses associated with developing and maintaining a system. Therefore, systems developers must identify and document all types of costs that contribute to the TCO. REJ stands for Reject, which is not a relevant term in this context. FDD stands for Feature-Driven Development and UML stands for Unified Modeling Language, neither of which relate to identifying and documenting indirect expenses.

Question 8

A common tool for showing the distribution of a questionnaire or sampling results is a vertical bar chart called a(n) ____.
A) flowchart
B) histogram
C) agile method
D) Venn diagram

Accepted Answer

A histogram is specifically designed to show the distribution of data, often used for questionnaire or sampling results. Flowcharts, agile method, and Venn diagrams are not suitable for this purpose.

Question 9

To evaluate ____, a systems analyst needs information about projected future volume for all outputs, inputs, and processes.
A) scalability
B) reliability
C) compatibility
D) applicability

Accepted Answer

Scalability refers to the ability of a system to handle increasing amounts of work. To evaluate scalability, a systems analyst needs to know the projected future volume for all inputs, outputs, and processes.

Question 10

When preparing a representative sample from a list of 200 customers who complained about errors in their statements, a ____ could ensure the sample is balanced geographically by selecting five customers from each of four zip codes.
A) systematic sample
B) stratified sample
C) random sample
D) comprehensive sample

Accepted Answer

A stratified sample involves dividing the population into smaller subgroups based on specific characteristics and then randomly sampling within each subgroup to ensure representative representation of that characteristic. In this case, the characteristic is geographical location (zip code). By selecting five customers from each of the four zip codes, the sample is balanced geographically and therefore more representative of the population of customers who complained about statement errors.

Question 11

The term ____ refers to a system's ability to handle increased business volume and transactions in the future.
A) scalability
B) reliability
C) compatibility
D) applicability

Accepted Answer

Scalability refers to a system's ability to handle increased business volume and transactions in the future. Reliability refers to the ability of a system to consistently and accurately perform its intended functions. Compatibility refers to a system's ability to work with other systems, software, or hardware. Applicability refers to the suitability of a system to a particular task or purpose.

Question 12

Wireless capability allows all of the following EXCEPT ____.
A) Web access
B) synchronization with office networks
C) random sampling
D) streaming multimedia

Accepted Answer

Wireless capability allows web access, synchronization with office networks, and streaming multimedia. However, it does not enable random sampling, as that is a statistical sampling method used in research and data analysis, and not related to wireless technology.

Question 13

Microsoft has developed a method for measuring a system's total costs and benefits, called ____, which is a framework to help IT professionals analyze and optimize IT investments.
A) TCO
B) REJ

Question 15

Some ____, which are enormously popular handheld computers, can accept handwritten input, while others have small keyboards.
A) PIMs
B) laptops
C) PDAs
D) Visios

Accepted Answer

PDAs (Personal Digital Assistants) are the handheld computers referred to in the sentence, and some models can accept handwritten input while others come equipped with keyboards. PIMs (Personal Information Managers) and Visios are not commonly used terms for handheld computers, while laptops are not typically classified as handheld computers.

Question 16

In an interview, ____ are questions that ask a person to evaluate something by providing limited answers to specific responses or on a numeric scale.
A) open-ended questions
B) closed-ended questions
C) leading questions
D) range-of-response questions

Accepted Answer

The answer of In an interview, ____ are questions that...

Question 17

If an interviewee gives only short or incomplete responses to open-ended questions, a systems analyst should do all of the following EXCEPT ____.
A) switch to closed-ended questions
B) give the interviewee easy access to supporting material that might be needed
C) try rephrasing open-ended questions into those types of questions
D) switch to questions with a range of responses

Accepted Answer

Providing easy access to supporting material may not improve the quality of the interviewee's responses. Instead, the interviewee may need additional clarification or encouragement to provide more detailed responses. Therefore, the best approach may be to try rephrasing open-ended questions or using questions with a range of responses, rather than switching to closed-ended questions or providing supporting material.

Question 18

When studying an information system, examples of actual documents should be collected using a process called ____.
A) stratification
B) randomization
C) indexing
D) sampling

Accepted Answer

Sampling involves collecting a representative subset of data from a larger population. In this case, actual documents from the information system would be the population, and selecting a sample of those documents would provide insight into how the system operates. Stratification involves dividing a population into subgroups before sampling, randomization involves selecting a sample at random without regard to specific characteristics, and indexing involves creating a searchable database of information.

Question 19

In a(n) ____ structure, which usually is based on interpersonal relationships, some people have more influence or knowledge than appears on an organization chart.
A) spontaneous
B) unstructured
C) informal
D) open-ended
