favourite brands of beer when the brand label is removed (Mauser, 2013). In the light of this, I have designed an experiment 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.

3.2.1 Local educational institutions Local educational institutions, which include formal institutions such as primary schools and second- ary schools, as well as non-formal institutions such as Community Learning Centres and community- based education programmes, are the key sources of data about education. Records kept in these institutions contain data about education in the local area and are particularly useful as the basis for reporting data in response to the annual school census. 3.2
EXPERIMENTAL RESEARCH DESIGNS There are a number of ways to ascertain the relationships between variables, one of which is the experiment. The advantage of an experiment is that it offers the best conditions for the control of extraneous variables, which are those variables that are present but which are not the focus of the study. The most widely used experimental designs are (a) Pre-experiments; (b) True experiments and (c) Field experiments (Quasi-experiments). PRE-EXPERIMENTS All the types
Experimental Design: Plant Density Aim: Effect of plant density on plant growth. Hypothesis: The closer of the seeds, the less growing will occur. Equipment: Water, sunlight, soil, fertilisers (if needed), Greenhouse (if needed), trowel, 5 pots, a pack of 1 gram garlic chive seeds (approx. 250 seeds), worms, measuring cup. Background information: Density-dependent growth in plants occurs when resources are limited. At high density, individuals must share resources, and thus a smaller amount
background studies are insufﬁcient. In other words, what question(s) do they leave unresolved that you would like to study? - Make sure you include your hypothesis, as well as, the independent and dependent variables. - Lastly, identify your research design. Dependent Variable: • What behavior are you going to measure? • How often are you going to measure the behavior? • What is the type of observation? • What is the recording method? How will data be recorded? Independent Variable/Subject Variable:
respondents who provide measures based on the experimental manipulation BLOCKING VARIABLES: A categorical (less than interval) variable that is not manipulated like an experimental variable but is included in the statistical analysis of experiments EXPERIMENTAL CONDITION: One of the possible levels of an experimental variable manipulation MAIN EFFECT: The experimental difference in dependent variable means between the different levels of any single experimental variable INTERACTION EFFECT: Differences

amounts of data into a small summary. Inferential statistics is best used to test the relationship between two variables. 2. What are the similarities between single case and small-N research designs? What are the differences? When should you use single-case and small-N research designs? Single case or the case study method is the intensive study of one individual.
psychology 1301109 24/10/2013 979 “A true experimental design as the most accurate form of experimental research, in that it tries to prove or disprove a hypothesis mathematically, with statistical analysis” Shuttleworth (2008). This means that an experimental design basically tries to see how accurate an hypothesis is through statistical analysis. So, for an experiment to be classed as a true experimental design, the sample groups must be assigned randomly, in which there must
