Introduction

In this assignment we needed to do a survey on smartphones users in Taylor’s

University Lakeside Campus. We had a total of five members which were Ooi Kai Yang,

Siau See Sing, Thun Shao Xun, Yee Algel and Egbert Chin Haw Hoong. It was our second

and notably our final group assignment which focused on statistics.

In this topic, we were required to apply all of our knowledge that we had learnt from

Miss Ann regarding statistics and its application in our survey. It all involved collecting data

from all the fill-out hand out and rearranging it and form out the different types of data

collecting to see which one fits our data.

We, as a group started to print out a total of 100 copies of the hand-outs. Then we

would be randomly distributing the hand-outs to any passer-by we met on that day. Soon after

that was done, we started collecting the data and organizing it in Microsoft excel form so we

could have an idea of which types of data collecting tools to use that suited our calculation.

After that was done, next up was formulating an A2 board showing all of info graphic work

and finally, a report.

Objectives

The objective of our survey was to compare the usage of smartphones and their

applications based on the different demographical age groups in Taylor’s University Lakeside

Campus. The reason why we chose smartphones as the main subject of our survey was

because as of now our generation is very technology and media based, our phones, or

smartphones, being a very important part of our daily lives. Likewise, the reason why we

chose age as a very defining factor is because we wanted to show the comparison of the

usage between age groups, as the amount of time, money and interest invested into

smartphones is increasing as we get closer to the younger generations. As of such, we thought

it would be a subject that many people can relate to and can easily understand. We did this

comparison by asking and selecting between specific age groups between the ranges of 18 to

23, and we focused on the amount of money spent, brands of smartphone, time as well as

specific applications that we deemed reasonable for these age group ranges.

We will be representing these ideas in the form of tables and charts, as well as

explaining the data in forms of paragraphs, since we believe that this method would make it

more functional and easier for anyone to read and understand, to gather data without

extensive background knowledge on what we did and how we did it.

In our survey, over 100 students between age group 18-23, there are 39 females and

61 males. Besides, young adults aged 21 is the modal class. The 22 age group is the least in

the data which only has 8 persons.

Therefore, we have actually assigned the ages into two specific groups, which are Teenagers

(18 to 20 years old) and Young Adults (21 to 23 years old).

Question 3: Which types of keypad phone did you use previously, before switching to a

smartphone?

Figure above shows the brand of mobile of each age group before they started to use

smartphone. They are too many types of mobile phone brands and so, the ‘others’ is the

highest in the bar chart. From the bar chart, the most welcomed mobile brand is Nokia and

the least welcomed mobile phone brand is Motorola. However, the number of young adults

who have used Motorola are obviously greater than teenagers.

Question 4: Which brand of smartphone do you prefer?

Figure above shows the type of smartphone used by the teenagers and young adults

which consists of Sony, Nokia, HTC Samsung and Apple. It is obviously that Apple is the

most welcomed brand among all the smartphones, because about 52% of people are using it.

Then, followed by Samsung which has 29% of people using it. Comparing both age groups,

both group prefer to use Apple then follow by Samsung. However, Sony is more preferred by

teenagers than young adult.

Battery Life

Young Adult Teenagers

Human need energy to work and therefore, smartphones need battery to function.

Figure above shows the battery life of the phones they have. The conclusion that can be made

is these people do not really charge their phones often due to the long battery lives.

Therefore, power banks in this scenario, are not really necessary. A smartphone’s battery life

usually lasts for 5-7 hours, as you can see from the bar chart above.

Charge How many time perday

Teenagers Young Adult

Based on the figure above, most people here charge their phones once per day. This is

common and logic because if we relate this question to the previous question, number 5, we

can conclude that the long battery lives of their smartphones causes them to charge not that

often. However, some people still need to charge often due to the frequent usage for

important purposes such as doing assignments.

Teenagers Young Adults

Based on above, it clearly shows that people usually have a smartphone rather than 2

or 3. This is because, with just one, we can already do a lot of things and it’s more than

enough. People who have 2 or 3 smartphones must really be big fans of them and they always

tend to change their smartphones often.

Question 8: Which functions do you use the most on your smartphone?

Teenager Young Adults

Smartphones are awesome devices that give us entertainment. Based on the figure,

many people like to use their smartphones to surf social apps. This is because the main

benefit of a smartphone is to be able to surf the internet social sites conveniently without

computer. Also, features such as camera, games and music can be run better in DSLRs, Play

Stations and iPod. Therefore, with these alternative, it’s no wonder out that they don’t really

use them on their smartphones.

Question 9: Which social media do you use the most on your smartphone?

As we know, Facebook is the most popular social site in the world, created by Mark

Zuckerberg. As on 3rd October 2013, there were 500 Million People use Facebook, and that’s

a huge amount of people! Therefore, people usually use Facebook the most on their

smartphones due to its popularity.

Question 10: Which feature of the smartphone is the most important to you?

Smartphone Feature


Based on the figure, we can know how important the features of Internet and the ability to

surf the social medias among other features on smartphones. Usually people won’t use the

camera because they have their alternatives such as DSLRs, compact cameras and many

more. Besides that, number of people that play games on the phones is lesser. This is because

the alternatives, such as PS3, XBOX, PSP and many more would give better performance in

gaming.

Question 11: What age did you start to use a smartphone?

Most people in this scenario are so fortunate and great, because they got their very first

smartphones at the age of 15, when they were middle school students. However, smart

phones may bring many benefits, but they must not abuse it. Some parents are worried of

getting a smartphone for their kids at a young age due to their maturity. At the age of 16,

student might have exam, so the number of the smartphone will drop. On the age of 17, the

number of smartphone that the student have increased dramatically due to the rewards from

their parents after SPM. There is a slight drop in 18 years old due to students started their

university life.

Type or Voice Message


Based on the bar chart, it’s obvious that the Young Adults prefer to use voice message rather

than typing. Perhaps these people prefer to socialize and chat with their voices. It is a good

sign for the young adults because if we chat with our voices, we would hear the other

person’s voice and expression, rather than chatting using words and emoticons that do not

feel realistic.

Based on the bar chart, it is obvious that people prefer IOS and Android over Windows. This

is because these two operating systems (OS) are the oldest operating systems for smartphones

and meanwhile, Windows is new in developing smartphone operating systems. It is highly

possible that they prefer older companies over the others because of the experience they have

got.

Question 14: How you take pictures using your smartphone

Young Adults

Based on the above figure, it shows that most of the teenagers (18yrs-20yrs) and young adults (21yrs-

23yrs) tend to use their phones to take selfies rather than asking someone else to take it for them.

This is because most of the selfies that are taken involves only one individual. On the other hand, we

will only ask someone help when we are with our friends and such. Also, there is a song named

“Selfie” sung by The Chainsmokers actually promotes and gives the idea of taking selfies awesomely.

Therefore, it’s no wonder out that they prefer taking selfie since this is a “culture” and that’s what

everyone’s been doing!

Question 15: Duration you take to change your phone

1 year 2 years 3 years 4 years0

Based on the above figure, it clearly shows that most of the students that ranges from teenagers to

young adults tend to change their phone after two years.

This is due to the fact that they might have misused or poor handling of their phones. Other than that

it is quite normal for them to change their phones after three to four years as the software tend to be

downgraded over the phones causing a few problems to the users.

While on the other hand, it is quite rare for them to change their phones after one year as their phones

are still in good conditions. So this results in a few changes for the one year period as it is most

probably caused by poor judgement when buying the phone of their choice.

Question 16: How much do you spend on your phone every month?

Rm1-Rm50 Rm51-Rm100 Rm101-Rm150 Rm151-Rm2000

Based on this figure, students tend to spend RM 1 – RM 50 and RM 51 – RM 100 more. This is

because students don’t usually spend so much money on their smartphones compared to the people

who work, such as businessmen. Businessmen usually spend money on their smartphones when

they’re in another country because they need the mobile network to make urgent and crucial phone

calls, it is called ‘rooting’ which is extremely expensive!

Question 17: What size of smartphone do you prefer?

62%

38%

Teenagers

Small Large

58%

42%

Young Adults

Small Large

Based on above, these students prefer small phones rather than large phones. This is because they may

think it’s lighter and convenient to bring. People who are older, such as the “Aunties and Uncles”

would prefer to use larger phones because as they grow older, they’re sight become worse and that’s

why they need a larger phone.

Question 18: How many smartphone cases do you have?

Smartphone cases are important if you want to protect your phone. Technically, 1 is enough.

Therefore, most people have one. Some people, however, like to change cases as their hobbies and

likes. This is common among people who is a big fan of smartphones and cases.

Question 19: What features do you look for while buying a new phone?

Camera Os Hardware Price0

Based on the graph above, operating system is the main criteria for Young Adults.

This is because different operating systems affect the productivity of the smartphone. Where

else young adults focus more on hardware. Hardware also plays and important role, different

hardware will produce different qualities software of the phone. Nowadays camera like

DSLR are heavy and inconvenient for the people. All thanks to the technology, smartphones

now can take picture with high quality resolutions. Smartphone cameras can also take

different kinds of picture and you can directly edit the picture without using your laptop or

computer. In price wise, 6 teenagers and 1 young adult did care about the price of the

smartphone. This shows that price does not matter, because the higher the price, the better the

functions and qualities.

Question 20: What service line do you use?

Digi Maxis Celcom U-Mobile0

In this chart above, we can see that maxis has got the highest rate of teenagers and young

adult who are using it. This is because Maxis provides better services and network coverage.

Where else Digi has the second highest rate compared to the other 2 companies. Digi

provides cheap plans but does not provide better services due to the poor network coverage.

U-mobile has more teenager that’s using it compared to young adults. U-mobile does provide

good service but the plan is too expensive compared to the others. Celcom has the lowest rate

among the other 3 companies. This is because Celcom’s plan is too expensive but they do

provide good network coverage.

Question 21: The need for power bank when going out

YES NO23

Based on the above figure, it shows that most of our teenage students tend to bring out their

power bank more than their young adults counterparts.

This is because the teenagers (18 yrs – 20 yrs) tend to use more of their phones for works,

assignments, checking out their notifications, chatting or just for playing games. This results

in them using a lot of power from their phones. So in order to solve this problem, a power

bank is a must for them when going out.

On the other hand, it is not such a serious case for the young adults as they have their iPads

and laptops along with them if their smartphones run out of power. What if their smartphones

are in low battery? They can actually charge them via a cable connected to their laptops.

Question 22: Do you have a data plan on your smartphone?

YES NO0

Based on figure, both teenagers and young adults have same opinions regarding the usage of

mobile data plan. Mobile Data Plan is really important to those who are always busy and

need to travel everywhere , such as businessmen, they may need to be able to access the

internet to read their emails, make video calls or even surfing the internet for urgent

information’s and news.

CONCLUSION

In this assignment, we learned the study of statistics. This assignment required us to

compare the survey of the age between 18-20 and 21-23. In this assignment, we had to

distribute 100 copies of survey form to the people to fill in the form. We had to analyse the

data according to the survey form that we distributed. Based on what we went through, I

think that different people have got different choices, just like what Walt Disney has said :

“The more you like yourself, the less you are like anyone else, which makes you unique.”

Nevertheless, the different age’s group of 18-20 and 21-23 may not be obvious, but

there are tremendous differences when they are making decisions and even what they like and

dislike. After doing this survey, we could understand more about the students’ thoughts.

As a conclusion, no matter what, there isn’t such thing as ‘better choice’ or ‘you have

no taste’. In the end, everyone is different and have got different choices. We have got to

learn how understand and acknowledge their decisions. However, there’s a saying: “The

more the people have it, the greater the product” It may be true, but still, totally up to you!
