Question 1

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 the population is more important in sampling because it determines the maximum sample size that can be used to have a representative sample. The percentage of the sample size, standard deviation, and average all depend on the absolute number of the population.

Question 4

Qualitative 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

Qualitative documents can be text-based, such as memos, signs posted on bulletin boards and in work areas, procedure manuals, and policy handbooks. Pictures, flags, and banners would not typically be considered qualitative documents.

Question 5

Data-gathering bias can be reduced by sampling.

Accepted Answer

Sampling involves selecting a representative portion of the population, which reduces the likelihood of data-gathering bias. By choosing a diverse sample, the results are more likely to be applicable to the entire population, decreasing the possibility of bias. However, sampling, even with a diverse population, cannot completely eliminate data-gathering bias.

Question 6

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 7

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 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

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

Accepted Answer

In most organizations, information flows from higher level to lower level, which is the downward flow. Information also flows horizontally between individuals or departments on the same level. Therefore, option A is the best choice as both downward and horizontal information flows are common in most organizations.

Question 10

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

Accepted Answer

Qualitative documents can come in various forms such as email messages, memos, or signs on bulletin boards. Therefore, all of the above options are correct.

Question 11

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 stands for "Strengthening the Reporting of Observational Studies in Epidemiology." It is a checklist of items to include when reporting observational studies in fields such as epidemiology, public health, and healthcare. The elements in STROBE include things like study design, population, data sources, variables, bias, and statistical methods. None of the elements listed in the choices (office location, desk placement, office lighting, desk chair fabric) are relevant to the STROBE checklist.

Question 12

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

Accepted Answer

Sampling only collects a portion of data from the population, which helps save time and resources.

Question 13

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 comfortable and relaxed atmosphere, which generally leads to casual communication. It is not necessarily indicative of any specific interest in external information or use of memos, as these can be present in any office environment regardless of lighting type. Formal communication may be more associated with brighter, cooler lighting.

Question 14

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

Accepted Answer

The passage explicitly states that the reports in question are comparing "actual versus intended performance," which pertains directly to the concept of performance. While sales and production may be factors that contribute to performance, they are not the focus of the comparison being made. Data capture is not synonymous with performance reporting and is not mentioned in the passage. Therefore, the best answer is A) performance.

Question 15

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 systems analyst is responsible for identifying the variables that need to be gathered in the sample. Constants refer to factors that do not change, and sample size and leaders are not directly related to this task.

Question 16

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 17

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 is widely regarded as a useful tool for assessing various variables in HCI (Human-Computer Interaction), interpersonal relationships, and organizational environments. It can be an indicator of a person's overall mood, their attitudes towards certain topics, their level of stress or anxiety, and their ability to communicate effectively. Additionally, the use of humor can also reveal cultural differences and attitudes towards diversity in a particular setting. Therefore, humor is a valuable barometer of several variables and can contribute to a better understanding of the dynamics of a given situation.

Question 18

________ 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 choosing a representative group from a population, often with the goal of making inferences about the larger population.

Question 19

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

Accepted Answer

This statement is true. Stratified sampling is a commonly used sampling technique in statistics and research methods, which involves dividing a population into subpopulations or strata based on certain characteristics or variables, and then randomly selecting samples from each stratum in proportion to its size or importance. This helps to ensure that the sample is representative of the population and can improve the accuracy and precision of estimates or inferences based on the data collected.

Question 20

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

Accepted Answer

Setting a sample size greater than one ensures that there is some variability in the data that is being collected, while setting it less than the size of the population ensures that the sample is representative of the population as a whole.
