Class Reflection – Week 9 By: Alyssa Karpouzis 999120179
What we learned:
In today’s class, the group presenting did their presentation on the case that was due this week
about Juice Guys. After their presentation, we discussed as a class about the case and how we felt
the researchers did when they were trying to establish a sample and develop research to see
whether or not the Juice Guys store would be a success. A main topic that we discussed was
about what type of research should be conducted whether it is qualitative research or quantitative
research. We established that if the researchers know what questions they want to ask then they
should do qualitative research. However, if the researchers do not know then they should do
quantitative research and exploratory work. After the discussion about the type of research,
another thing to know is that the order of the questions matter. This is because the sequence of
the questions could result in biased answers.
My Participation:
During this class I participated several times and below I have just stated examples of when I
participated. To start off with, as soon as the presenters finished their presentation I began the
class discussion and asked a question about what type of sampling should the researchers have
used. I suggested to the class that the stratified sampling method should be used and I explained
why that method would have been a good method. I also went on to explaining about why other
types of sampling methods would not be as beneficial. The professor also asked me a question
during the class about if I thought anything was wrong with the sample that the researchers chose
in the case and I said that they did not pick a good sample because they selected people that were
not from the Boston area and the people they selected were already involved with smoothie/juice
companies. Another instance where I participated in class is that I said that the biggest question
that had to be answered in the case was whether or not Juice Guys would be successful. When
the professor asked about what other questions market researchers would have to consider, I said
that they would also have to collect data about what type of products consumers would purchase
in the shop so therefore, what type of products Juice Guys should sell whether it was juice,
smoothies, merchandise, healthy snacks, etc. Another instance of when I participated in class was
that at the end, the professor asked what type of scale would be a good scale to use and I
suggested a Likert scale because it is an unbiased scale. Overall, these were just some examples
of when I participated in the class.
