Research Question: Would the packaging of a famous brand affect people’s rating on a product?

Introduction
Many people believe that brand names tell the quality of a product (Erdem, 1998). They tend to choose products on a basis of brands. Yet, it was found that many people enjoy drinking their favourite beer the most only when the brand label are shown. Most of them could not identify their favourite brands of beer when the brand label is removed (Mauser, 2013). In the light of this, an experiment has been designed to see whether people’s rating on a product is influenced by the provision of the packaging of a famous brand.

Experimental Design and Procedures
In this experiment, the product used is mini egg custard mooncakes of the restaurant “Spring Moon” from The Peninsula Hong Kong. The hypothesis is the packaging of a famous brand affects people’s rating on a particular food. The independent variable is the packaging of a famous brand. Its operational definition is the packaging of mooncakes from Spring Moon, which is a box showing the brand name clearly. The dependent variable is people’s rating on a particular food. Its operational definition is to give marks on the taste of the mooncake, which is rated by the participants. The full mark is 10. The higher the marks, the tastier the mooncake is.
The experiment will be conducted in a mobile lorry. There will be only one participant and two observers inside the lorry. The target participants are adults from Hong Kong. Random sampling will be adopted. The lorry will be driven to different districts, so that 50 participants will be randomly chosen and invited to attend our experiment. Also, single-blind procedure will be used. Participants will not know the aims of this experiment.
After choosing the participants, randomly assignment will be used to group the participants into experimental group and control group. Each group will have 25

    Experimental Design and Quasi- Experimental Design Cherry Spelock Ohio University An experimental study is defined by the way a researcher manipulates independent variables to prove or disprove a hypothesis. Outcomes are then measured and recorded. Experimental studies are considered one of the most valid ways of determining causal relationships (Byiers, Reichle, & Symons, 2012). When the independent variable cannot be controlled or other factors important to the study are out of the…

    Experimental design is a research method in which researcher tries to examine causal effects by manipulating independent variable under controlled settings and measures whether it produces any change to the dependent variable. In an experiment experimenter deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response. This differs from an observational study, which involves collecting and analyzing data without changing existing conditions. In an experimental…

    A fundamental characteristic of experimental approaches in relation to psychological studies is that researchers can observe and analyse certain behaviours in an environment of that they can control. By exposing participants to certain treatments or conditions, researchers are able to attain identification of causality. There are two primary designs in which experimenters can construct said treatments or conditions. In a “within-subjects” design experiment, all participants are exposed to every…

    Critical Appraisal of a Quasi-Experimental Design Nursing research is an essential part of a nurse’s profession; it has a remarkable influence on current and future evidence-based practice (Tingen, Burnett, & Murchison, 2009). Therefore, it is vital that nurses develop the skill of critiquing a research paper to know how to read and understand those reports. Because evidence-based practice is embedded in the foundation of nursing, it is vital that nurses develop the ability to recognize research…
