    CCN1017 Introduction to Psychology Experimental Design 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...

  • Experimental Design and Quasi- Experimental Design
    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...

  • Advantages and Disadvantages of the Experimental Design
    * Advantages and Disadvantages of the Experimental Design Advantages: * As well as controlling the independent variable the experimenter attempts to eliminate unwanted extraneous variables. * Control over extraneous variables is usually greater than in other research methods. * Experimental design involves manipulating the independent variable to observe the effect on the dependent variable. This makes it possible to determine a cause and effect relationship. * Because of strict...

    Lab 3: Experimental Design & Hypothesis Testing 1. Some observations found about termites are that they live in moist, dark environments, they are sterile and lack eyes, and their primary task is to collect food. From this information the hypothesis that due to their lack of eyes, they use feeling of their skin to find what they are searching for and a pencil line would give a feeling of wood that would attract the termites. By making a course that split into two paths of a pen line and pencil...

  • Essay Experimental Design - 1108 Words
    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...

  • Basic Experimental Design Concepts
    "The term experimental design refers to a randomization plan for assigning participants to experimental conditions and the statistical analysis associated with the plan. The simplest experimental design is the randomization and analysis plan that is used with a t test for independent samples. A t test for dependent samples uses a more complex randomization plan, but the added complexity is usually accompanied by greater power. The next level of design complexity is the randomization and...

    THE LOGIC OF EXPERIMENTAL DESIGN The randomized comparative experiment is one of the most important ideas in statistics. It is designed to allow us to draw cause-and-effect conclusions. Be sure you understand the logic: • Randomization produces groups of subjects that should be similar in all respects before we apply the treatments. • Comparative design ensures that influences other than the experimental treatments operate equally on all groups. • Therefore, differences in the response...

    Question 1. When deciding on the research design, one choice is whether to use an experimental or non-experimental design. This depends on the aim of the study. If the aim is to test a prediction that two or more variables are simply associated with each other, the researcher may decide to use a non-experimental or correlational design. However, if the aim is to test a prediction that there is a causal relationship between two variables, then an experimental design is needed. The correlational...

    In psychology, the experimental method involves the manipulation of some aspect of a situation, and observing the effects this has on a particular behavior. In technical terms, the former is the independent variable (IV), and the latter the dependant variable (DV). Only the investigations which involve the manipulation of the independent variables is part of the experimental method. Basically, in other words, we can say that experimental method is the type of research which involves the...
