Experimental Designs II - Assignment Example For example, in a 2x2 factorial ANOVA with levels A1 and A2 of Factor Aand levels B1 and B2. An ANOVA test would test the significant differences between the marginal means, which are called simple Main Effects of each factor. This is because they illustrate the overall difference between the levels of each factor, independently of the levels of the other. The ANOVA also tests for the significance differences between the Cell Means; in other words, the four means relevant to the AxBinteraction effect (Jackson, 2012). According to Jackson, the test also determines if the effects of the independent variable (IV) are independent of each other, or whether the effects of one IV depend on the level of the factor. Key effects are differences in means over levels of one factor that is collapsed over levels of the other factor (s) (Jackson, 2012). No.6 The difference between a complete factorial design and an incomplete factorial design is laid out in how experimental conditions are dealt wit h. A Complete Factorial Design (CFD) consists of all factors and levels of each factor, it is also capable of estimating all factors, and their interactions (Jackson, 2012). An incomplete factorial design is arrived at when experimental conditions are removed from a complete factorial design. ... No.8 The difference between a two way ANOVA and a three-way ANOVA is that a two-way ANOVA test is used when there are more than one IV requiring multiple observations for each IV. The two-way test determines the main effect contributions of each IV and indicates if there is a significant interaction effect amongst the IVs. The three way ANOVA is used to determine the effect of three nominal predictor variables that are based on a continuous outcome variable. The three-way test evaluates the effect of the IV on the expected outcome together with their relationship in the outcome (Jackson, 2012). Random factors are considered to have no statistical impact on a given data set, unlike systematic factors that are considered to hold statistical significance.

Analyzing Ragged Dick and comparing its depiction of status and Essay

Analyzing Ragged Dick and comparing its depiction of status and identity with that of Black Protest and the Great Migration and - Essay Example The boundaries which are created through each story show how culture is based on creating divisions within society because of stereotypes, status and ways in which relates to material goods. The first concept related to identity and status and the divisions which this creates in American society comes from the ideal of class. In each of the stories, there is a division of class which occurs, specifically between the lower, middle and higher classes. The point which is made with each of these classes shows that this is based on wealth and money, which allows any individual to change their class if they can make wealth. When these specific classes clash or the information about wealth is recognized, then it creates the division. For instance, in â€Å"Ragged Dick,† Dick is known to have lived on the streets and without a home; however, if this is disclosed to those in the middle class, which he is trying to turn to through wealth and money, then it will create division. For inst ance, when he is seen walking with Frank, there is recognition that Frank has a wealthy home while Dick has been on the streets.1 This information shows the divisions between class and how it turns from financial situations into social status. The concept of social status and the relationship to wealth is not only important in determining divisions between rich and poor. The concept of status created more divisions that were based on other stereotypes created within American society. One’s identity was furthered with divisions of color, race and the area which one was from, such as displayed in â€Å"The Great Migration†.2 This story is similar to that of Dick’s, specifically because the looks which one has and the ethnicity which they belong to create the same division. The identity then relates to the class which one belongs to. The revelation in this story is important because it defines not only divisions created in American society through race, but shows h ow society has created the boundaries of identity beginning with stereotypes of race, then leading to wealth expectations, neighborhoods which one should live in and the lifestyles which one has. Each of these attributes of division are seen with the movie â€Å"Lady and the Tramp† as a way of showing how the identity and status become a sense of conflict. The main plot of this story shows how a dog from the other side of the tracks falls in love with a mongrel from the other side of town. When looking at the division between these two, it can be seen that there are complexities with wealth, looks, race and the class divisions between the two. The boundaries are based on the identification of several attributes which are incorrect in the two being together3. This creates the central conflict in the story and shows how division is based on the superficial identities which are created in society. The differences which occurred within in society and identity, all which are divid ed according to the wealth, ethnicity and identity of an individual, come into conflict when the stereotypes of class are no longer effective. The economic, social and political concepts tie together, specifically because of the status which is held. If one has a specific social status based on wealth, then begins to change into a
