Assume that you must choose between a face-to-face survey and a web-based survey. What is the trade- off between threats that you are dealing with and how would that influence your decision as to which method to use?



Answer: A face-to-face survey will probably have higher experimenter realism (i.e., the subject will take the questions seriously) but it will also evoke higher levels of reactivity (mostly evaluation apprehension) in the subject. So, if the issues being studied are "touchy" (such that subjects would have a better reason to give inaccurate/dishonest answers, go with the web-based study. If it is crucial that the subjects really think about their answers, go with the face-to-face survey.

Discuss the seven characteristics of useful information. Answer: The seven characteristics of useful information are: relevant, reliable, complete, timely, understandable, verifiable and accessible. These characteristics are qualities that information should possess to be useful in a business environment. Briefly stated, in order for information to be useful it must be: 1) relevant, meaning that it reduces uncertainty and adds to the decision-making process; 2) reliable information is information that is free from error, and is accurate in its nature; 3) complete information is information that does not omit any important data, facts, or aspects about events or activities; 4) information is timely when it is fully available to enable the decision-making process to proceed; 5) understandable information must be both in an intelligible and useful format; 6) information is considered verifiable if two people, acting independently of each other, produce the same inform

Why have accounting software packages been designed with separate transaction modules?

Why have accounting software packages been designed with separate transaction modules? Answer: : Since every organization does not necessarily use all of the transaction cycles in its operations, it is to the advantage of the organization to be able to "pick and choose" from among various software modules that track and record different transaction cycles. For example, a law firm would have no need to implement a production cycle module. Also, the nature of a transaction cycle varies across the broad spectrum of business organizations. Again, a law firm would have a revenue cycle, but it would not involve the purchase, receipt, and payment for products or merchandise; likewise a retail store chain may not sell any consulting services to its customers.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved. (Be sure to clearly state the principles addressed in your discussion.)
