## Math 1

Description: I chose these cover letters because I wanted to show an example of my self reflection from the beginning of the year compared to the end, and see what differences and similarities there are.

Cover Letter

In reflection of my overall “mastery” of this unit, I believe it’s an improvement in comparison to the amount of effort I’ve applied to the other units, but that still doesn’t amount to much more than a basic (if not mediocre) understanding of the unit concepts. I understand in the sense that I can collect or use a set of data, graph it and determine an ideal curve and the equation that correlates (incorporating the parent equations) which is best demonstrated in the curve fitting worksheet where we found the best mileage for a VW Jetta. I was also introduced to Normal Distribution and Standard Deviation. I thought it was obvious that it was a way to measure a spread of data, however I learned what a standard deviation from a mean is, how that would be visually represented and the percentages required in a set of data to fall within 1,2 and 3 standard deviations from the mean, and how looking where the curve changes from concave up to concave down can show the length of 1 standard deviation. The mastery grade I’ve chosen to give myself is a 15/30, because I feel I’ve learned and retained the raw content itself, but I still lack vital aspects of completion like describing the unit question and how to answer it. As for my growth, it’s been lackluster throughout the year as a student as well as a person, but this specified period of time has been better than the others. I’ve actually made an effort to understand and demonstrate the content (like in the curve fitting and normal distribution worksheets) and in that small area I feel I’ve improved as I’ve been pushing harder than I usually do, but in reality my growth has been one of my biggest issues for the past few years and this unit made an insignificant dent in it. That’s better than nothing though.

I’m curious about the normal curve of the U.S.’ financial status in population compared to other countries. In that regard, my question would be the following; What is the average financial income in the U.S. and what does it look like within 3 standard deviations? Also, is there a specific social class that falls between the second and third deviation?
