Our first

quantitative variable is: (Height). The unit of measurement for this variable

is (inches). A few possible values for this first quantitative variable are (72

inches), (65 inches), and (70.5 inches). Our second quantitative variable is:

GPA (grade point average). The unit of measurement for this variable is (scale

0.00 to 4.00). A few possible values for this second quantitative variable are

(2.00), (3.33), and (4.00). Our research question is “Is height of a student”

related to “GPA?”

To answer

this research question, we will gather data as follows: We will randomly select

25 men and 25 women and ask them what their height is (in inches) and what

their current GPA is. This will be done in the stratified sampling method. Each

member of our team has classes and those classes were placed in a hat. Then

three of the classes were drawn at random from the hat and each member of those

classes was asked these questions on a piece of paper: 1) What is your height

in inches? 2) What is your current GPA? 3) What is your gender? After filling

out the paper they folded it and handed it back to the surveyor without the

surveyor seeing the answers. These papers were then placed back in a hat and

drawn in random order until we had 25 men and 25 women. There were no

replacements used.

#### My Reflections

*For our project we asked the question is the height of a person related to their GPA. So we conducted a survey to find out the answer to this question. Our results showed no relation to a person’s height and their GPA. There appeared to be no correlation between the two.*

*The difficulties we experienced on this project were 1) some students didn’t want to report to us their GPA. 2) We had to go on the honor system concerning a student’s GPA. This posed a problem because many of the students surveyed reported GPA’s of 3.5 or higher. With several of them reporting perfect 4.00. This appeared to us to be higher than one would think would be the average. Having said this, the conclusion of the survey and the statistical analysis of it did show no correlation between GPA and height. This would seem to comply with common sense, as IQ is not determined by a person’s height. Nor is a person’s motivation to work hard and study, all precursores to receiving good grades and thus having a good GPA.*
