Assignment 1

On 3rd December 2015, a survey was conducted among undergraduate students who

joined the Ningen Ryoku class at the University of Technology Malaysia Kuala Lumpur

Campus. The purpose of the survey was to discover the most favorite flavor of the

students toward the Hattendo cream buns. Six flavors of the cream buns which were

chocolate, custard, matcha, whipped cream, red bean and strawberry were provided to

students for a tasting survey session.

The survey was divided into two sessions which were pre survey and main

survey. During the pre survey session, a talk was given by President of the Hattendo

Company, Mr Takamasa Morimitsu and six favours of the cream bun were introduced

and presented visually to the students. Students were asked to rank their favorite flavors

through their instinct. Then, a tasting session was conducted and students were asked to

rerank their favorite flavors in the main survey. According to the data, 126 students are

expected to join the surveys, however, only 125 students turned up in the pre survey and

120 students were participating in the main survey. The response rate for the survey are

99.2% and 95.2% respectively in pre survey and main survey.

Result of the pre survey is shown in the Figure 1 and the main survey result is

shown in Figure 2. According to the pre survey result, the first most desired cream bun to

eat is custard and chocolate which get the percentage of 24.8% and 24% of respondents

while the most not interested to eat in the first place are red bean and strawberry with

only 8.8% and 7.2%. The highest percentage of the second most desired cream bun to eat

is whipped cream with 24.8% while custard stay at the second highest with 19.2%. In the

third most desired cream bun to eat, custard occupies 22.4% which is the highest and

matcha with 12% is the lowest percentage. Figure 3 shows the trend of the ranking, as we

can see, the custard flavor post a trend of irregularly decrease in the percentage from

24.8% to 9.6% which is the decrease of 15.2% while red bean and strawberry flavor show

an irregularly increase in the percentage from 8.8% to 20.8% and 7.2% to 24%

respectively. Matcha flavor posts a quite stable trend and the percentage hike to highest

percentage which is 27.2%  in the 6th most desired cream bun to eat. In short, before the

tasting session, we can conclude that custard is the flavor most desired to eat by the

respondents while the strawberry and red bean are less favorable by the respondents to

eat.

The result of the post tasting session which is the main survey shares almost the

same trend with the pre survey. This can be compared and seen from both of the Figure 3

and Figure 4 which shows the both ranking trends of pre survey and main survey. The

data of the main survey shows that custard is the 1st favorite flavor respondents like which

occupies the highest percentage 29.2% while the least favorite are red bean with only

10%. Then, chocolate being ranked at the top of the 2nd favorite with the percentage of

22.5% followed by custard with 20.8%. In the third favorite, the custard share the highest

percentage with 20.8%. Custard post a gradually decrease trend as shown in Figure 4,

custard flavor with the 29.2% on the 1st favorite has been decreased to 8.3% on the 6th

favorite with a 20.9% decrease while chocolate also shows an irregularly decrease from

25% to 6.7% with a decrease of 18.3%. In other words, this shows that chocolate and

custard are the most favorite flavors to the respondents while both strawberry and red

bean which post a gradually increase trend are the least favorable flavors to the

respondents. Strawberry and red bean increase from 11.7% to 25.8% and 10% to 25%

from 1st favorite to 6th favorite respectively. The whipped cream shows an uncertain trend

while matcha shows a quite stable trend.

In conclusion, the flavors which show the gradually decrease in percentage from

the 1st to 6th are more flavorable by the respondents compared to the flavors that show

gradually increase in trend. Hence, we can conclude that custard, chocolate and whipped

cream are the top 3 favorite flavors while strawberry,red bean and matcha are less

favorite to the respondents.
