IQ Tests and the Normal Distribution – IQ tests are a type of assessment that measures cognitive abilities. They provide a score that is intended to serve as a measure of an individual’s intellectual abilities and potential. IQ scores follow a normal distribution, i.e. bell curve.
Begin by reviewing the normal distribution and how to calculate probabilities associated with it:
• This video will review the important features of the normal distribution, https://www.youtube.com/watch?v=mtbJbDwqWLE
• This video shows how to calculate probabilities using the normal distribution in Statcrunch, https://www.youtube.com/watch?v=H_O2GcFCDCw
Next, review the websites below that discuss various IQ tests and how their scores are distributed:
• This website reviews the types of IQ tests (Weschler IQ Test and Stanford-Binet) and how they compare on the normal curve, http://www.assessmentpsychology.com/bellcurve.htm
• This website provides IQ classifications (Very Superior, Superior, High Average, Average, Low Average, Borderline, Extremely Low), and the IQ scores that are associated with those classifications for the Wechsler Adult Intelligence Test, http://www.assessmentpsychology.com/iqclassifications.htm
In your main post, do the following:
1. Select a particular IQ test, such as the Weschler or Stanford-Binet.
a. Describe how the IQ test measures intelligence.
b. Proide the mean and standard deviation of the test.
c. Discuss what score values fall within 1, 2 and 3 standard deviations of the mean and what the Empirical Rule tells us about this.
2. Select a random IQ score.
a. Calculate the probability of a person scoring at least this high. In other words, the probability of a person achieving this score or a higher score. You may use technology to find this value.
b. How is this score classified on the IQ test’s scale (i.e. Average, Above Average, etc.)?
c. Based on the information above, do you think this score is appropriately classified? Please explain from a statistical standpoint as well as a personal perspective.

What is the relationship between anxiety and long hours worked among women?

• The first assignment of the project consists of a descriiptive analysis that motivates the research question and the proposed hypothesis, the statement of the research question and of
the guiding hypothesis in such a way that they can be analyzed through statistical inference
methods. The students are asked to identify a research question that is relevant for them,
state the hypothesis and motivate the relevance of the research question and the proposed
hypothesis.
• The second assignment of the project asks students to state the causal mechanisms that they
want to analyze in the study using the different tools of the potential outcomes framework
and, in general, those of causal analysis.
• Finally, the students are asked to identify the appropriate empirical strategy for their question, providing a robust argument for their methodological selection and highlighting the
data necessary to address the research question with the specified empirical strategy to obtain causal results. The students are not asked to perform the empirical analysis themselves,
but if they are motivated to do so, the effort will be rewarded.

Grades
The project as a whole represents 20% of the course’s final grade. Each partial submission represents 5% of the final course grade, and the final, complete submission represents the 10% left.
As the partial submissions will receive feedback from the instructor, the 10% of the final submission will not necessarily correspond to the performance in the partial submissions. However,
submission of the materials in the intermediate due dates is mandatory for the final submission
to be considered towards the final grade of the cours

Big data is everywhere, and various businesses around the world are driven by big data. While some businesses rely on big data for organizational decision making, this does not mean that the implications and applications of big data are properly used to ensure optimal effectiveness for the organization

For this scenario, you have been appointed as a business analyst for Big D Incorporated, charged with providing authoritative recommendations to the Board of Directors. As the business analyst, the recommendations that you provide will be based upon data calculated from statistically appropriate formulas. Be reminded that you are not the company’s statistician yet. However, as the business analyst, you are therefore responsible for interpreting statistical data and making the appropriate recommendations.

Big D Incorporated was offered a series of business opportunities, and it is your job as the business analyst to provide expert insight and justification for recommendations regarding these potential prospects.

Big D Incorporated needs to prepare an assessment regarding the feasibility of making a recommendation for expansion into another market. The new market is in Chicago with the 60614 zip code.

You have just received your next assignment that will contribute to your next decision. For the outdoor sporting goods client, based upon your prior decision on whether or not to expand to the next market or retain your current position ( I choose to expand to the new market in the Chicago withe the 60614 zip code), justify your decision further utilizing the chi-square distribution tool. One key criterion point: You do not have adequate data to formulate a full chi-square for the outdoor sporting goods client. However, you have sufficient data to initiate this process. You are charged to demonstrate the initial steps of a nonparametric test that are qualitative. Utilizing the null and alternative hypotheses, further present your justifications for your selection and what it means beyond the mere formulas. What is this going to tell the Board of Directors and contribute to the decision-making process?

The following are assumptions that might make the assignment more helpful and make the responses more uniform:

Continue to utilize the Big D scenario. Work under the assumption that the sample is based upon 2 different proposed product lines.
Additionally, work under the assumption that the same demographics are utilized for each product.

The powerpoint attached will help support why I choose to expand in Chicago.
