I will also place 2 classmate post for a response. Unable to post until I post my initial post. Please be aware I will also need responses to post
POST 1
If my learning path in ALEKS is any indication, transcription errors seem to be my biggest problem, followed by the occasional interpretation error. Several of my failures to clear a topic without providing an incorrect answer are the result of either typing/clicking the wrong number or symbol (a malfunctioning mouse isn’t helping) or seeing a word problem like one I’ve just completed and failing to catch one of the variables in the word problem was changed. You’d think by now I’d realize I won’t see the exact same problem twice! As a result, I’ve learned I need to double-check my entries before I hit submit, and make sure I pulled the right numbers out of a word problem.
Since starting this course, my confidence level has risen slightly. I attribute this in large part to ALEKS and how it approaches introducing topics. I find myself making it through probably 80-90% of the problem sets it throws at me without making any errors. The learning path and explanation buttons seem to be all I need in most cases - I’ve really only opened the textbook when doing the problem sets to see how my assigned problem lines up with the examples listed.

1. Agree or disagree with one of the Math Myths listed above. Find a link to one article on the Internet to support your response.
I agree with all of the myths listed except for myths 1 and 5. I do believe that the most important thing in math (as far as the U.S. education system appears to be concerned with) is getting the correct answer. In addition, I believe that math is a very logical and calculating field that often requires a keen analytical mindset. I do not agree with the statement that men are better than women at math in natural sense as this could be blamed on a societal construct versus anything from nature. For example, teachers often underestimate the ability of females to perform math functions, leading many of them to abandon the idea of pursuing a professional career in the field by the 8th grade (AAUW 2). While this is obviously a hot-take that is not true in the slightest, it is easy to see this being the case from a historical point of view. However, times have changed and this is no longer the case. Women have pursued careers in this field at a much higher rate; so much so that I can say that I’ve only had 1 or 2 male math teachers in my entire life versus dozens of female teachers. In addition, I am not above admitting that I am not that great at math and I am sure there are plenty of women within this class and outside of here that are much better at math than me. This statement, while dated and continuously evolving, is simply incorrect.
2. Share your own current or former feelings of math anxiety. Explain how you plan to deal with it in this course.
This is the first time I’ve heard this phrase before and I can genuinely say that I have a pretty rough case of math anxiety. When I first registered for classes at UMGC, I contacted my advisor and told her to tell me what the simplest math class is because I am “too stupid for anything else”. Part of that is just my sense of humor but another part of that is because I have always struggled with math and I was just saying how I felt albeit lightheartedly. Preparation is my key to getting through this anxiety; ensuring I stay ahead of the work and don’t have to rush through everything at a later date to avoid the feeling of being overwhelmed will help me avoid these thoughts. After all, I’ve made it this far by doing this and I can make it through this class by keeping this up.

I'll address Math Myth #1: Aptitude for math is inborn. I disagree with the statement - to a point. However, there a certain stereotypes associated with math that have elements of truth which tie in to this myth. I recall listening to a podcast a couple years ago which broke down the "Asians are good at math" stereotype and why it often appears to be true. Perhaps the thing I found most intriguing was discussion of a Chinese language (I don't recall if it was Cantonese, Mandarin, or both) and how it is constructed in such a way that numbers can be communicated much more efficiently than in English. Rather than having weird linguistic constructs like "eleven, "twelve", "fourteen" and "thirty-seven", the Chinese language(s) use mono-syllabic words to say "one ten and one", "one ten and two", "one ten and four", and "three tens and seven". Additionally, aspects of culture play into approach to learning as well. So, aptitude for math isn't inborn, but some people are exposed to things at an early age and given tools that enable them to excel at math.
The article I found supports both points of view, and basically concludes that certain abilities related to mathematics, such as pattern recognition, may be inborn; however, crunching numbers isn't can't exist without numbers and a way to write and say them. dissenting viewpoint addresses precisely what I described in the previous paragraph.

Stanford University Probability Distributions Calculations
Imagine if you were offered a job in a different state and a major consideration for you is rent prices (assuming you planned to rent instead of buy). Your main concerns are the affordability in relation to your income and the location/condition of the property. Perhaps you would look for the cheapest rent possible within a quiet, residential community. Or, you might be willing to spend at little more than average to live in the heart of downtown. As you research the city, you learn that the mean for rents of your preferred home size are $1,300 a month. Many people might base their decision on this number alone, but you—equipped with the knowledge of standard deviation—know there is more to that number.If the most you could afford is $1,100 a month in rent, then a standard deviation of $250 might be good news because the amount you can afford is still within 1 deviation of the mean. With a standard deviation of $75, however, you might be unwilling to make the sacrifices necessary to rent a place that you could afford. Additionally, if you were willing to spend a little more than average to live in a nice place or area, then you could easily find an amazing place with a standard deviation of $100 but might not be able to afford the upgrade with a standard deviation of $300.In this Discussion, you will use the data that you gathered in the Week 1 Discussion to calculate a standard deviation and explain how this concept can affect decision making.To prepare for this Discussion:Review this week’s Learning Resources.Locate the data that you gathered for the Week 1 Discussion.Calculate the sample standard deviation from your cigarette price data in Week 1. Use that (and your sample average and sample size) to calculate the following (assuming a normal distribution):Within what range would you find 90% of cigarette prices in your area?What are the chances that someone in your area would pay 4 dollars or less per pack?What are the chances that someone in your area would pay 10 dollars or less per pack?Review the Academic Writing Expectations for 2000/3000-Level Courses, provided in this week’s Learning Resources.BY DAY 3Post a 150- to 225-word (2- to 3-paragraph) explanation of how probability distributions affect management decisions. In your explanation, address the following:Provide your results of the following:Your calculations for your standard deviationThe range within which 90% of the prices of cigarettes in your area fallsThe chances of anyone paying less than 4 dollars for a pack of cigarettesThe chances of anyone paying more than 10 dollars for a pack of cigarettesDescribe what implications this concept has for management decision making.Explain how you might use information like this in your current work.To support your response, be sure to reference at least one properly cited scholarly source.

Estimate the model and report results. Note: You are expected to perform regression diagnostics and report that as well.Once you perform your analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Part 2 Assignment:Write a 2- to 3-page analysis of your multiple regression using dummy variables results for each research question. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output.By Day 7Submit Parts 1 and 2 of your Assignment: Testing for Multiple Regression.
