Intro to Statistics - MATH 1040
Welcome to the Math 1040 - Intro to Statistics coursework page. This course was in my Spring Semester of 2013 and finishes the current mathematical requirements for my Associate of Science degree in Psychology.
I was presented with an option of Math 1040 (this course) or Math 1050 to complete the requirements and I, obviously, chose statistics. The reason for this choice is this; I work as an analyst full time for InterContinental Hotels Group and am quite frequently presented with data that requires a statistical analysis. It would be good to better understand exactly what I am doing as I analyze these data sets and also better understand how to communicate my findings.
As a result of this course I have already seen an improvement in the quality and efficiency of my work.

Reflection:
This class included a group project. I'll be the first to admit that I do not care much for group projects in a school environment and especially not in an online class. That being said the project, in no small part due to my group, went very smoothly.
We were divided into groups, our group consisted of seven people and nearing our first deadline for topic choice and data collection plan I was more or less elected to be the group spokes person. The members of the group that were participating at this point chose to study the relationship between the number of children an adult woman has and the amount of sleep she receives per night. We decided on a collection plan modeled as follows: To provide for a random sample of the population each group member was to select a location or multiple locations and survey every third adult woman they encountered, to determine the number of children she had and the amount of sleep she receives in an average night. This sampling method would continue until each group member had recorded a minimum of fifty (50) records. If each group member participated fully we would have 350 records.
To my surprise I received collected data from all seven group members and we completed the data collection phase with 356 records. As spokesperson I compiled all the data into one table, submitted it to our professor and then made it available to the members of the group so they could complete their individual written reports.

While completing my own written report I found the linear correlation coefficient for our two variable to be 0.042 with a required critical value of 0.195. Comparing the required critical value for a linear correlation and our coefficient it was apparent that our data did not have a linear relationship. This means that our data indicates no linear relationship between the number of children a woman has and how much sleep she receives.
Thus far I have talked solely about the processes of accomplishing this project and to this point it was pretty much roses. The challenges came into being as we embarked on the next section of the group work: the Visual Presentation.
I gathered the group together again and asked if anyone wanted to do a specific slide or sets of slides for the presentation and there were a few takers. Assignments were made for the slides and a requested due date to have them back was provided. All group members with exception of two provided their slides on time. Those others, one informed me the day before our due date that they had withdrawn from the class, and another the day of the due date that they would be unable to complete the slide due to a work emergency. I resolved to complete these additional slides myself when one of our other group members asked if I needed any help and offered to take on of the additional slides.
This project provided real world application of some of the concepts and statistical analysis we learned in class, which made the use of and application of those concepts in my daily life much easier.
