Comparative Study on Mobile Operating System of the Students of Liceo de Cagayan University

Ms. Stephanie Monte Probability & Statistics Class Adviser


CHAPTER 1


Background of the Study

 The

research is all about the operating system (OS) of mobile devices that is widely used by the students of Liceo de Cagayan University. OS are the main software that hosts all other programs in your cellphones. To help you understand OS more, the following are examples of operating systems (OS) of mobile devices. “iOS” for iPhones, “Windows Phone” for some latest Nokia and Sony Ericson models, “Android” for latest Samsung, Alcatel, Cloudfone and etc., “Blackberry OS” for Blackberry mobiles and many others.


Objectives of the Study

ď‚›This

study aims to compare mobile operating systems currently in-used by the public, particularly by the students of Liceo de Cagayan University; and to be able for us to find out the most widely used mobile operating system. More specifically it aims to know the OS of choice of the students excluding money constraints.


Significance of the Study

ď‚›This

study will benefit the researchers, the students and the readers of the output of this research. This will enlighten the minds of the readers to the latest trends of not only mobile devices but also the latest trends in mobile devices’ operating systems. This can be their guide to buying the best, the most stable and the most widely used operating systems of the latest mobile phones.


Scope and Delimitations  This

study will only cover mobile operating system. The mobile’s brand, model, and or manufacturer are not included in the study, but they are being used in the study as a reference, in order for the researchers to identify the mobile’s operating system of the one being surveyed, if ever he/she is unsure, or no knowledge at all of his/her mobile’s OS. The research also focuses on cellular phones. Other mobile devices such as PDAs (Personal Digital Assistants), Tablets, Mobile Gaming Devices and the like which do not have the capacity to text, and or call are excluded.


CHAPTER 2


Definition of Terms ď‚› Mobile

Phone- A mobile phone (also known as a cellular phone, cell phone, and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area ď‚› Mobile OS (Operating System)- A mobile operating system, also called a mobile OS, is an operating system that is specifically designed to run on mobile devices such as mobile phones, smartphones, PDAs, tablet computers and other handheld devices. ď‚› OS (Operating System)- An operating system (OS) is a collection of software that manages hardware resources and provides common services for programs


Definition of Terms  Android

OS- The Android mobile operating system is Google's open and free software stack that includes an operating system, middleware and also key applications for use on mobile devices, including smartphones.

 Blackberry

OS- The BlackBerry OS is a proprietary mobile operating system developed by Research In Motion for use on the company’s popular BlackBerry handheld devices

 Bada

OS- Bada is a proprietary Samsung mobile OS that was first launched in 2010. The Samsung Wave was the first smartphone to use this mobile OS.


Definition of Terms  iOS

(iPhone Operating System)- iOS or iPhone Operating System is the operating system supported by Apple’s own manufactured devices such as iPhone, iPad, iPad 2 and iPod Touch and is not open for third party licensing.

 Symbian

OS- Symbian is a mobile operating system (OS) targeted at mobile phones that offers a highlevel of integration with communication and personal information management (PIM) functionality. It is the mobile OS of the Nokia manufactured phones before it shift to Windows Mobile OS.


Definition of Terms  Windows

Mobile OS- Windows Mobile is Microsoft's mobile operating system used in smartphones and mobile devices with or without touchscreens  Hardware (Mobile)- Hardware is the machine, wiring, and other physical components of a computer or other electronic system.  Graphical User Interface (GUI)- The available interface of your phone. It is consist of icons, color of icons and is the way how graphics look in your cellphone.


CHAPTER 3


Methodology ď‚›This

study uses the methods of nonprobability sampling. The Quota Sampling. Since the population of the School (Liceo de Cagayan University) is big and to minimize the expenses, the researchers will set quota to be reached as a sample size to be surveyed. The base characteristic of getting the sample quota will be the gender such as male and female.


Methodology  Presentation

of Data- In presenting data, researchers will use the tabular presentation using either percentage or frequency table or using cross tabulation or both. To present the data gathered graphically, the researchers will use the bar chart.

 Sample

Size Determination (n)- To determine the Sample size “n”, the researchers will be using the quota sampling method. This means, the researchers will just set a quota to be met as a sample size. In this research, the researchers set 100 as sample size with 50% is set to be female respondents and the other 50% will be male respondents.


Methodology  Standard

Deviation (s) Determination s2 = ((nΣXi2 – (ΣXi) 2) ÷ (n (n-1)) s = √s2 Where n = the sample size and s is the standard deviation.

 Sample

Mean Determination Sample mean = (1/n) (ΣXi) Where n = the sample size.


Statistical Treatment  Hypothesis

Testing- The researchers wish to know the operating system of choice of the students of Liceo de Cagayan University. With the sample size of 100, we found out that 45% of male and female students wanted to have an Android OS. Is there a reason to believe that the number of students who want an Android OS is not 50, at α=0.05?

 Given:

n=100; sample mean=45; α=0.05; μ0 =50


Statistical Treatment 

Hypothesis. H0: μ=50 and H1: μ≠50

Significance level. α=0.05

Test Statistic. Since this is a test concerning population mean where σ is unknown and the sample size is greater than or equal to 30, we apply case 2. Hence, the appropriate test statistic is z= (sample mean- μ0) ÷ (s ÷ √n)

Critical Regions. Since this is a non-directional test, we apply a two-tailed test whose critical regions, as provided in case 2. z <- zα/2 or z >z α/2 z <- z0.025 or z >z0.025 Thus, we reject H0 if z <-1.96 or z>1.96, otherwise, we fail to reject H0.


Statistical Treatment  Computation.

The actual value of test statistic is: z= (45-50) ÷ (5.43 ÷ (√100)) z= (-5) ÷ (5.43 ÷ 10)  z= (-5) ÷ (0.543) z= -9.21

 Statistical

Decision. Since z = -9.21 is in the critical region, that is -9.21 < -1.96, we reject the null hypothesis, H0.

 Conclusion.

The test result provides sufficient evidence that the students who want an Android OS are not 50.

CHAPTER 5


Conclusion ď&#x201A;&#x203A; The

over-all satisfaction of users with grade rating interval of 6 to 10 for their mobile OS in this study says 100% for Blackberry OS; 90% for iOS; 87.5% for Symbian; 88.9% for Windows Phone; 86.1% for Android; and the lowest grade rating for mobile OS comes from others with grade rating of 75.8% and is compose of operating systems which are not famous and less known.


Conclusion  So

who’s the best OS? On some level, it’s too crude a question to take very seriously. There are just too many ways to define “the best,” and neither platform leads in every area. But here’s the closest thing to an objective answer we can manage. “Android is the best if you’re talking about market share; iOS if you mean financial success. So far, this is a strikingly different market than the PC business back in the 1990s, when market share translated directly into financial success.”


Conclusion

ď&#x201A;&#x203A;You,

of course, are entitled to come to a different conclusion because the best OS for you depends on your needs and tastes.
