Answer the following questions, covering material from Ch. 13 of Methods in Behavioral Research:

1. Define inferential statistics and how researchers use inferential statistics to draw conclusions from sample data. (3 points)

According to Cozby (2009),”inferential statistics are used to determine whether we can, in fact, make statements that the results reflect what would happen if we were to conduct the experiment again and again with multiple samples” (pg. 245).

2. Define probability and discuss how it relates to the concept of statistical significance. (2 points)

Probability is the possibility that an outcome of an experience or an event will occur (Cozby, 2009). Probability and significance are one in the same. For instance if the statistical significance is low then the difference will be counted as a random error, whereas if it is high it will not. If the significance is low then the probability is considered sound.

3. Explain the relationship between the alpha level (or significance level) and Type I error. What is a Type II error? How are Type I and Type II errors different? (3 points)

A significance level α corresponds to a certain value of the test statistic,
So the probability of rejecting the null hypothesis when it is true is the probability that t > tα, which is α.
In other words, the probability of Type I error is α.1 A Type I error occurs when your reject a true null hypothesis (remember that when the null hypothesis is true you hope to retain it). A Type II error occurs when you fail to reject a false null hypothesis (remember that when the null hypothesis is false you hope to reject it). The best way to allow yourself to set a low alpha level (i.e., to have a small chance of making a Type I error) and to have a good chance of rejecting the null when it is false (i.e., to have a small chance of making a Type…...

...Ch.5 Problems and Exercises 1. One of the potential problems mentioned in this chapter with gathering information requirements by observing potential system users is that people may change their behavior when observed. What could you do to overcome this potentially confounding factor in accurately determining information requirements? (Hoffer 148) Employees under observation do in fact act differently than if they were left alone. One way to circumvent the process is to watch them when they do not know they are being observed. Observing over time is another way to be unobtrusive in their environment. An employee acting natural is the key to business operations data collection success. The analyst could also develop anonymous interviews, anonymous surveys, etc to get a more accurate depiction of employee and business operations. Utilizing multiple data collections would result in more accurate data assessments. 3. Suppose you were asked to lead a JAD session. List ten guidelines you would follow in playing the proper role of a JAD session leader. (Hoffer 148) JAD sessions need to be conducted absent workplace. Attendees need to be briefed on the reasoning behind the JAD session with written agendas handed out to each one. All matters MUST be neutral in support (Do not sway one way or another). Participation is a must; each attendee needs to be proactive in the session to handle the issues at hand. Ground rules and issues will be noted during the session while......

They have special talent, such as to regulate their emotions. They have a high sense of self-efficacy and an optimistic worldview. They possess a strong faith or sense of meaning in life.

Week 7 Exercise

...Week 7 Exercise As an entrepreneur I would be very concerned about the amount of power that investors would have in my company. This legally binding document states that not only will the investors own a certain percentage of the company, but are given a set number of seats on the board of the company. The investors should definitely make there money back and should definitely have equity in the company but I would argue that they shouldn’t have as much control within the company in respects to making business decisions. The investors who are giving so much to this company should be concerned about their investment being squandered. If they are giving millions of dollars to a company, they have to make sure that the company is profitable and that they will see a return on their investment. The only way to do this is by having board members who have a say in what goes on in the everyday operations of the company. The investors should also be concerned about the events that will take place should the company fail or go out of business. In the event that the company’s assets are liquidated, there has to be language in the clause that clarifies how much the investors will receive since they are providing most of the funds used for the business. Both the investors and the owners of the company should be worried about the direction of the company and who controls that direction. Even with owning the company, the owners have to give a say to the investors......

...CHAPTER 7: ADVANCED OPTION STRATEGIES END-OF-CHAPTER QUESTIONS AND PROBLEMS 1. (Bull Spread) Buy one put with exercise price X1 and sell one put with exercise price X2. The profit equation is ( = Max(0, X1 – ST) – P1 – Max(0, X2 – ST) + P2 If ST < X1 < X2 ( = X1 – ST – P1 – X2 + ST + P2 = X1 – X2 – (P1 – P2) Recall from Chapter 3 that the difference between exercise prices is less than the difference between premiums. Since X1 < X2 and P1 < P2, the above profit is negative. If X1 < ST < X2 ( = – P1 – X2 + ST + P2 This figure increases dollar for dollar with ST. The breakeven is found by setting the profit to zero, – P1 – X2 + ST* + P2 = 0 and solving for ST* ST* = X2 + (P1 – P2) If X1 < X2 ( ST ( = – P1 + P2 Since P2 > P1, this figure is positive. The minimum profit occurs in the first profit range, ST < X1 < X2 and equals X1 – X2 – (P1 – P2). The maximum profit occurs in the third profit range, X1 < X2 < ST and equals – P1 + P2. 2. (Straddle) A straddle is a strategy based on the expectation that the market will have high volatility. If, however, everyone else in the market believes that the market will have high volatility, then the prices of the call and put will reflect the higher volatility, which will result in breakeven points further away from the current stock price. A straddle is most likely to be successful when the investor believes that the market will be more......

...Chapter 7 Vision – expresses an organization's fundamental aspirations and purpose, usually by appealing to its members' hearts and minds. A vision statement may add soul to a mission statement if it lacks one. Over time traditional statements of mission (example stating the business in which the organization is involved) may change, but the organization's vision may endure for generations. The following statements represent the visions of three organizations: Lowe's – to be our customer's first choice for home improvement in each and every market we serve eBay – to pioneer new communities around the world built on commerce, sustained by trust, and inspired by opportunity. Dell Computer – To create a company culture where environmental excellence is second nature. Bringing value to customers and adding value to our company, our neighborhoods, our communities and our world through diversity, environmental, and global citizenship intiatives. Many organizations don't have a vision statement. They may have a mission statement only. Mission – the organization's purpose or reason for existing. Mission statement answers basic questions such as: 1) What business are we in? 2) Who are we? 3) What are we about? A mission may describe the customer needs the firms aims to satisfy, the goods and service the firm supplies, or the markets the firm is currently serving or intends to serve in the future.
