Hypotheses, Causal Model, and Operationalization Form Essay

Hypotheses, Causal Model, and Operationalization Form - Essay Example Thus, anyone who eats a balanced diet or eats well will have to live longer than those who do not. C) Draw a causal model of your hypotheses—using textboxes, arrows, and proper notation. If you do not already know how to create textboxes, or resize textboxes, or draw and move arrow, or align plusses and minuses along the lines, or make all of the lines and arrows black— this is when to learn. In terms of layout and formatting, your model ought to look like those in the samples and exercises from class. (Simply bump it all to the next page if you need additional space.) 5. Where You Have Access to Data for Your Time Period and Cases to Actually Measure the Variable as Operationalized Above (NOT ‘hope’ to find and have access to, or ‘might’ find and have access to, or ‘will start to look for’ or anything other than KNOW where the needed info/data is and KNOW you have access to it.) The variables will be measured using the most appropriate methods for each of them. Since they have a direct influence on the findings, the choice of the variable will have to be made after considering its effectiveness. For instance, while dealing with eating habits as one of the variables in the research, the researcher will have to conduct a thorough survey to ensure that the most appropriate and proportionate population sample is studied and analyzed. This will help in ensuring that the research is accurate and valid to be relied

Movie Review - Essay Example The flask was then place on the magnetic stirrers of the bench and then stirred. 0.5mL of p-anisalaldehyde was then dissolved in 2mL of ethanol into the beaker and then swirled to mix the reactants well. The p-anisalaldehyde solution was then added drop wise with the pipette to the acetone and NaOH solution for a given period of time before the next drop was added to ensure that the solution was mixed well. The reaction was stirred well for 25 minutes. The color change of the solution provided the visible indication of the product formation. At the end of the experiment, the stir bar was returned to the instructor and left the magnetic stirrer on the table. In the Dianisalacetone synthesis, acetone was used as a reagent in the reaction. During the experiment, 3 mL of aqueous NaOH solution was added to 25mL flask then later on 10 mL of acetone was added. The flask was then place on the magnetic stirrers of the bench and then stirred. 1 mL of p-anisalaldehyde was then dissolved in 10 m L of ethanol into the beaker and then swirled to mix the reactants well. The p-anisalaldehyde solution was then added drop wise with the pipette to the acetone and NaOH solution for a given period of time before the next drop was added to ensure that the solution was mixed well. The reaction was stirred well for 20 minutes. At the end of the experiment, the stir bar was returned to the instructor and left the magnetic stirrer on the table. To find the isolation and purification of Anisal or Di-Anisalacetone, the reaction mixture was diluted in the Erlenmeyer flask 10mL of tap water. After submitting to the supervisor, the diluted mixture was then transferred to the separatory funnel found at the HOODS. After draining the yellow organic layer, the solution was later dried with the anhydrous sodium sulfate and then filtered into the round bottom flask. The solvent was later removed with the help of the rotary evaporator and water bath found at room temperature. The
