PHASE TWO: Plus Minus Grading System Opinions of Flagler College Students in Fall 2016

Introduction:

On the first phase of this project, the plus minus grading system opinionsof a sample of 150 Flagler College students from fall semester 2016 was explored.  In this phase of the report, this same sample of 150 students will be divided into two smaller samples.  The two samples are the sample of Flagler College students who have previously attended a school that used the plus-minus grading system and the sample of Flagler College students who had not previously attended a school that used the plus-minus grading system.  For purposes of this report, the two samples will be defined with a simple phrase.  The term “Plus-Minus Students” will define the sample of those Flagler College students who have previously attended a school that uses the plus-minus grading system and the term “Not Plus-Minus Students” will refer to the sample of those Flagler College students who did not previously attend a school that used the plus-minus grading system.  There are 76 Plus-Minus Students and 74 Not Plus-Minus Students sampled.

Students surveyed answered many other questions.  They reported their academic standing, their GPA, and other opinions of the specifics regarding the plus-minus grading system .  In this report, three comparisons will be investigated.  First, a comparison will be made between the reported hours spent studying per week between the Plus-Minus and Not Plus-Minus Students.  Then the responses to if they were aware that Flagler used the grading system and if they thought if the grading system was profitable toward students will be compared between the Plus-Minus and Not Plus-Minus Students.

Comparison #1: Hours Studying Weekly

The following stacked boxplots and corresponding summary statistics represent the hours spent studying weekly for the Plus-Minus Students and Not Plus-Minus Students.  One of the Plus-Minus Students stated that she spent 50 hours a week studying.  Since there are 168 hours per week, this is incredible but not impossible.  Therefore, this student is included in the sample for this comparison.

Overall, there was not much of a difference in the reported time spent studying per week between the Plus-Minus Students and Not Pls-Minus Students.  The median hours spent studying for the Plus-Minus Student was 10 hours per week while the median hours spent studying for the Not Plus-Minus Students was the same 10 hours per week. The upper and lower quartiles for the samples were slightly different the first group at 6 and 20 hours and the second group at 5 and 15 hours. The minimum and maximum number of hours studying per week were also very similar (at 0 and between 45 and 50 hours respectively).  Both sample distributions had outliers.  In fact, the upper fence of 20 hours for the Not Plus-Minus Students was greater than the upper fence of 15 hours for the Plus-Minus Students.  This goes against my intuition that the Not Plus-Minus Students would spend less time studying because they believe the plus-minus grading system is going to bump their GPA up.  Furthermore, the variability of the responses is the slightly different between the two groups based on an IQR of 14 hours for the Plus-Minus Students and 10 hours for the Plus-Minus Students. It seems that those students who have not yet experienced the plus-minus grading system slightly tend to study longer during the week.

Comparison #2: Knew Flagler’s Use of Plus-Minus Grading

The following split bar plot shows that Plus-Minus Students and Not Plus-Minus Students differ in their responses to their knowledge of Flagler College’s use of the plus-minus grading system.  Approximately 61% of both groups were not aware and approximately 48% of both groups were aware.  This is certainly an interesting result.  Regardless of a students’ previous experience of plus-minus grading in school they still have a greater chance of not being aware of Flagler’s grading system. This may be a positive factor when thinking about how a student decides on a college. They may be better off not knowing before choosing to keep their interest in programs the school provides a priority. 

Comparison #3: Plus-Minus Profitable toward Students

The following contingency table compares the responses to Plus-Minus Profitable toward Students between the Plus-Minus Students and Not Plus-Minus Students.  Overall, 98 out of the 150 students surveyed believe that plus-minus grading system is profitable while only 52 students do not.  Thus, 65.3% (98/150) of all the students surveyed feel that plus-minus grading system is profitable.  Therefore, the majority of the students surveyed feel that plus-minus grading system is profitable.

Of the 74 Plus-Minus Students surveyed, 54 feel that plus-minus grading system is profitable and of the 76 Not Plus-Minus Students surveyed, 44 feel that plus-minus grading system is profitable.  That is, 73.0% (54/74) of the Plus-Minus Students feel that plus-minus grading system is profitable while 57.9% (44/76) of the Not Plus-Minus Students feel that plus-minus grading system is profitable. There is certainly a significant difference in opinion on the profitability of the plus-minus grading system between these groups.

Conclusion

 

In this comparison of the opinions between the students surveyed who did previously attend a school that used the plus-minus grading system (Plus-Minus Students) and those students surveyed who did not attend a school that used the plus-minus grading system (Not Plus-Minus Students), it was found that these two groups did not differ in the time they invest studying each week and there was a very high percent of difference in their knowledge of Flagler’s use of the plus-minus grading system.  It was found, that the two groups did differ in their opinion on how profitable they thought the plus-minus system would be for students.  More of the students surveyed who came previously from a school with the plus-minus grading system (Plus-Minus Students) felt the grading system would be profitable than the students surveyed who did not previously attend a school with the plus-minus grading system (Not Plus-Minus Students).  This is not surprising to me.   If a student has had exposure and experience, then they are more apt to embrace the plus-minus grading system as a part of their academic measurement (and hopefully success) and would consider it to be profitable, possibly because of familiarity.
