Aim:

Recently in the our year group, selling
chocolate (specifically Freddo's and medium
sized Cadbury blocks), has been a popular
method of fundraising. It was our aim to
determine which chocolates were most
popular through our survey, and
consequently be able to increase the profits
and minimise losses of these sellers.
How the survey was
conducted

We conducted our survey by simply
walking up to year 9 girls with a printed
questionnaire. We chose to do this method
because we found people were much more
likely to take time to complete the survey if
it was face to face, compared to alternatives
such as online surveys. This method
effective because everyone we asked did
take the time to complete the questionnaire.
Results: What is your favourite type of
Freddo chocolate?
Strawberry
Chocolate 6%

Crunchie
Chocolate 8%
Milk Chocolate 32
%
Peppermint
Chocolate 6%
Caramello
Chocolate 20%
Popping Candy
Chocolate 6%
White Chocolate
10%
Dark Chocolate
12%
Analysis

From this data it is clear that people prefer
plainer types of chocolate; with the majority
of the preferences being the plain flavours
(milk chocolate with a preference of 32 %,
dark chocolate with a preference of 12%, and
white chocolate with 10%). Caramello was
also immensely popular with 1/5th of all
preferences, however all of the other
unconventional flavours had less than 10%
preference.
Results: Do you prefer $1 freddos (35g) or
$2.50 Cadbury blocks (85g)

$2.50 For a Small
Block
28%
$1 for a Freddo
72%
Analysis

There was a significant difference of peoples
preferences between the two, with only 28%
choosing the small Cadbury blocks, and 72%
choosing Freddos. As the survey was being
conducted many people justified their
choose by stating Freddos are better value,
however per dollar a block is 34g and a
Freddo is 35g, only a 1g difference. These
results also infer that people are more
willing to spend money in small amounts.
Conclusion
From this survey we were able to conclude
that the most popular type of chocolate was
milk, and Freddos were preferred over
blocks. Consequently if we were to
implement these results the most successful
box would look like this:
