Question 1

Which of the following is not an element observed in STROBE?
A)office location
B)desk placement
C)office lighting
D)desk chair fabric

Accepted Answer

STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) is a reporting guideline that includes items related to study design, analysis, and interpretation. None of the items listed in the options are included in the STROBE checklist, but desk chair fabric is the least related to the study design or analysis.

Question 2

Quantitative documents include memos, ________ on bulletin boards and in work areas, procedure manuals, and policy handbooks.
A)signs
B)pictures
C)flags
D)banners

Accepted Answer

Quantitative documents refer to written materials that provide specific information or data. Examples of this include memos, signs on bulletin boards and in work areas, procedure manuals, and policy handbooks. Therefore, the best choice to complete the sentence would be option A. Options B, C, and D do not fit the definition of quantitative documents as they are not written materials providing specific information or data.

Question 3

The duties and responsibilities of the systems analyst are to identify the ________, the attributes, and even the associated attributes that need to be gathered in the sample.
A)sample size
B)constants
C)variables
D)leaders

Accepted Answer

The duties and responsibilities of a systems analyst include identifying variables, which are the characteristics or attributes being studied in the sample. Sample size, constants, and leaders are not directly related to this task.

Question 4

A good rule of thumb is to interview at least ________ people on every level of the organization.
A)three
B)two
C)four
D)five

Accepted Answer

The answer of A good rule of thumb is to...

Question 5

Data-gathering bias can be reduced by sampling.

Accepted Answer

Sampling can help reduce data-gathering bias by ensuring that data is collected from a representative subset of the population, rather than just from one specific group or location which may be biased.

Question 6

Stratification is the process of identifying subpopulations (or strata)and then selecting objects or people for sampling within these subpopulations.

Accepted Answer

This is an accurate definition of stratified sampling.

Question 7

Observing ________, their physical environment, and their interaction with their physical, ergonomic environment is an important unobtrusive method for a systems analyst.
A)software developers
B)administrative assistants
C)decision makers
D)receptionists

Accepted Answer

The answer of Observing ________, their physical environment, and their...

Question 8

________ provide periodic updates of what is occurring in the business.
A)Performance reports
B)Records
C)Data capture reports
D)Blank forms

Accepted Answer

The answer of ________ provide periodic updates of what is...

Question 9

Sampling helps accelerate the process by gathering selected data rather than all data for the entire population.

Accepted Answer

Sampling allows for a representative subset of data to be collected and analyzed, thereby saving time and resources compared to collecting data from the entire population.

Question 10

The absolute number is more important in sampling than the percentage of the ________.
A)sample size
B)standard deviation
C)population
D)average

Accepted Answer

The absolute number of individuals sampled from the population is more important than the percentage of any other variable. This is because the absolute number determines the representativeness of the sample and the accuracy of the statistical inference made from the sample to the population. A larger sample size generally leads to more accurate estimates of the population parameters.

Question 11

Typically, most information flows ________.
A)downward and horizontally
B)upward and vertically
C)Both A and B.
D)Neither A nor B.

Accepted Answer

Most information flows downward from management to lower-level employees and horizontally between employees at the same level. Upward communication is less frequent and mostly includes feedback and reports from employees to their superiors.

Question 12

An office lighted with warm, incandescent lighting indicates a tendency toward:
A)formal communication.
B)gathering information from memos.
C)casual communication.
D)a person that is interested in external information.

Accepted Answer

Warm, incandescent lighting creates a cozy and relaxed atmosphere, which suggests a tendency toward casual communication. This type of lighting may not be the best for formal communication or reading memos, and it does not necessarily indicate an interest in external information.

Question 13

The simplest method of probability sampling is called ________ sampling.
A)convenience
B)systematic
C)simple random
D)purposive

Accepted Answer

The answer of The simplest method of probability sampling is...

Question 14

When the systems analyst asks an opinion of a permanent feature of the installed information system, the executive interviewed may provide an unbiased evaluation since there is little possibility of changing it.

Accepted Answer

The answer of When the systems analyst asks an opinion...

Question 15

________ is the process of systematically selecting representative elements of a population.
A)Questioning
B)Calling
C)Sampling
D)Learning

Accepted Answer

Sampling is the process of selecting a representative sample from a population in order to make inferences about that population. This involves choosing a subset of individuals or items from the larger group that share similar characteristics or traits. This can be done using a variety of methods, such as random sampling, stratified sampling, or convenience sampling, depending on the research need and available resources.

Question 16

Assessing use of ________ provides a quick and accurate barometer of many HCI, interpersonal, and organizational variables.
A)humor
B)anger
C)rage
D)indifference

Accepted Answer

Humor can serve as a valuable indicator of many different factors in HCI, interpersonal interactions, and organizational dynamics. For example, the use of humor can help to establish rapport and create a positive atmosphere, both of which are important for effective communication and collaboration. Additionally, the type and frequency of humor used can reveal information about personality, values, and priorities, as well as group norms and social dynamics. Overall, tracking the use of humor can provide valuable insights into a wide range of factors that influence communication, collaboration, and organizational effectiveness.

Question 17

It is necessary to set a sample size greater than one but less than the size of the population itself.

Accepted Answer

A sample size greater than one is needed to capture variability in the population and reduce bias in the sample. However, the sample size should not be the same as the population size since this would defeat the purpose of sampling. Instead, a smaller sample size can provide reliable estimates of population parameters if it is randomly selected and representative of the population.

Question 18

When the systems analyst selects a group of documents or people to study, it is an example of ________ sampling.
A)cluster
B)simple random
C)purposive
D)systematic

Accepted Answer

The answer of When the systems analyst selects a group...

Question 19

Qualitative documents include:
A)email messages.
B)memos.
C)signs on bulletin boards.
D)All of the above.

Accepted Answer

All of the listed options (email messages, memos, signs on bulletin boards) are considered qualitative documents as they relate to communication and contain non-numeric information.

Question 20

Most ________ reports take on the general form of actual versus intended performance.
A)performance
B)sales
C)production
D)data capture

Accepted Answer

The statement clearly mentions "actual versus intended performance" as the general form of the reports, which indicates the topic is related to performance reports. Sales, production, and data capture reports are not mentioned and are not related to the given information.
