2. The Race for 2013 Senatorial Election
Rationale: As I approach the May 2010 election. Our group conducted a quick survey to test the Filipinos’
maturity and integrity in choosing their candidates in our democratic institution. Thus, this project will try to
determine the bet of some of our fellow countrymen for the presidential race in the May 2010 election.
Statement of the Problem: The aim of this first term statistical research project is to find out who is JRU
students’ choice for president in 2010. Specifically, it will try to find the following:
1] The profile of the respondents according to
a] gender
b] age
2] JRU students’ choice for president
3] Male JRU students’ choice for president
4] Female JRU students’ choice for president
5] JRU students’ perception of their candidates’ chance of winning the presidency in the 2010 election
6] Male JRU students’ perception of their candidate’s chance of winning the presidency in the 2010 election
7] Female JRU students’ perception of their candidate’s chance of winning the presidency in the 2010 election
8] JRU students’ degree of optimism that their choice for president can make a difference in the lives of Filipino
people
9] Male JRU students’ degree of optimism that their choice for president can make a difference in the lives of
Filipino people
10] Female JRU students’ degree of optimism that their choice for president can make a difference in the lives
of Filipino people
11] If there is a significant difference on the degree of optimism between male & female JRU students that their
choice for president can make a difference on the lives of Filipino people
12] If there is a significant difference on the proportion of votes garnered by ESCUDERO & VILLAR as the
JRU students’ choice for president

3. Hypotheses Tested:
The following hypotheses were tested at 0.05 level of significance:
1] Hypothesis on mean: Our group wants to know if there is a significant difference on the average degree of
optimism between male and female respondents that their choice for president can make a difference on the
lives of Filipino people.
Ho: µEscudero = µVillar; There is no significant difference on the average degree of optimism between JRU
male and female students that their choice for president can make a difference on the lives of Filipino people.
Ha: µEscudero ≠ µVillar; There is a significant difference on the average degree of optimism between JRU
male and female students that their choice for president can make a difference on the lives of Filipino people.
2] Hypothesis on proportion: Our group wants to know if there is a significant difference on the average degree
of optimism between male and female respondents that their choice for president can make a difference on the
lives of Filipino people.
Ho: PEscudero = PVillar; The proportion of votes garnered by Escudero and Villar are equal.
Ha: PEscudero ≠ PVillar; The proportion of votes garnered by Escudero is significantly higher than the
proportion of votes garnered by Villar.
Population and Sample: The population in this research is JRU students who are enrolled this first semester SY
2008-09. Our group has estimated JRU for having 22,000 students enrolled this first semester of SY 2009-10.
Using Slovin’s formula and a 5% margin of error, the required number of samples is 393. (Please see
computation below.) But our professor only required us to gather 200 samples, but our group managed to gather
up to 250 samples. Our group decided to use random sampling. Thus our samples are 115 randomly selected
male and 135 randomly selected female UE students.

Sampling and Data Gathering Techniques: Our group used simple random sampling in choosing the 250 sample
respondents in this research. We also utilized the indirect or questionnaire method. The group distributed 250
questionnaires from June 25 to July 2 to UE students around the campus. Our group had contacts inside the UE
campus, thus making things easier to get in touch with UE students. Having only 3 members in the group the
group divided the questionnaires into 3, with 2 members having 75 questionnaires each and 1 member having
100 questionnaires. From June 25 to July 2 our group would drop by UE to randomly give out survey
questionnaires to UE students, and with the help of our contacts in UE, our group was able to have access inside
the UE campus, thus giving the group more respondents for the survey.
Research Design: Our research is descriptive comparative since we will be comparing the responses of male and
female UE students.
Questionnaire: The questionnaire is composed of three items. The 1st
item asks the respondents about their
choice for president in 2010. The 2nd
item asks about their choice’s chances of winning the presidency. The last
item is a likert scale composed of five statements which try to assess the respondent’s degree of optimism that
their choice for president can make a difference on the lives of Filipino people.

Do not reject the null hypothesis
Following is the 5-step solution:
1] Ho: µMale = µFemale; There is no significant difference on the degree of optimism between male and
female UE students that their choice for president can make a difference on the lives of Filipino people.
Ha: µMale ≠ µFemale; There is a significant difference on the degree of optimism between male and female
UE students that their choice for president can make a difference on the lives of Filipino people.
2] 05.0=α ; p-Value = 0.338934
3] Decision Rule: Reject Ho if p-Value(0.338934) < α(0.05)
4] Decision: Do no reject Ho because p-Value(0.338934) > α(0.05)
5] Conclusion: There is no significant difference on the degree of optimism between male and female UE
students that their choice for president can make a difference on the lives of Filipino people.

18. Statement 12: if there is a significant difference on the proportion of votes garnered by Escudero & Villar as UE
students’ choice for president.
Below is the PHStat printout for testing the significance of difference between the number of votes garnered by
Escudero and Villar as the respondents 1st

Following is the 5-step solution:
1] Ho: pEscudero = pVillar; There is no significant difference on the proportion of votes garnered by Escudero
and Villar.
Ha: pEscuero > pVillar; The proportion of votes garnered by Escudero is significantly higher than the
proportion of votes garnered by Villar.
2] 05.0=α ; p-Value = 0
3] Decision Rule: Reject Ho if p-Value(0.0000000000329151) < α(0.05)
4] Decision: Reject Ho because p-Value(0.0000000000329151) < α(0.05)
5] Conclusion: The proportion of votes garnered by Escudero is significantly higher than the proportion of votes
garnered by Villar.
INFERENCE: If this trend will continue, and if election is held today and the voters are only UE students then
Escudero is a sure winner.

leader dropped out of class, and as
Co-Leader I had to take over as the
leader of the group, and I did my
part as the new leader of the group
by closely monitoring the progress
of our research work.

INDIVIDUAL REFLECTION
MY ELEMSTA EXPERIENCE
Leader: Mark Anthony Quijano_
I learned a lot in my ELEMSTA class, and I know these things will help me out in the next subjects that I will
be taking up in the next semesters, surveying for example will be helpful when I do feasibility studies, and in
my course Export Management that will have a big factor when I start doing my thesis. Also things were made
easier for us by our professor so the research work wasn’t really that hard. But overall my ELEMSTA class was
a learning experience.
Co-Leader:_Robert Santos_
ELEMSTA for me is a good learning experience. It gave me an idea on how to gather data, it could even help
me in the future when I finish my college years, the subject to me is challenging yet fun, it feeds me idea on
how I could survey on things, well I could even use it on my years here at CSB. The most thing that’s why I
really love ELEMSTA is we can choose where we want to survey so we could go to the place and really survey
people and meet new ones. I really felt the importance of this subject, it really opened my eyes on things how
people really gather data here and else where, with the help of our professor I really learned a lot.
Analyzer:_Michael Catabran_
My experience in ELEMSTA is fast and easy one. There was some difficulty on some lessons but most of the
time, it was mostly easy to understand. I didn’t expect ELEMSTA to be this easy as I’m not that good in math
but thanks to an excellent method of teaching it wasn’t a problem.
