Instrumentation. The research instruments for this study were developed by the researcher and are titled “Principals’ Quality Assurance Strategy Questionnaire “(PQASQ), “Teachers’ Role Performance Questionnaire (TRPQ) and Students’ Academic Performance Records Proforma” (SAPRP). The instruments are structured in Likert scale format of Strongly Agree (SA.), Agree (A), Strongly Disagree (SD), and Disagree (D), from which respondents are to tick as applicable to their opinion. It is divided into sections A and B. Section A contains personal information about the principals and teachers, while Section B contains information on variables of quality assurance strategy and teachers’ role performance in relation to students’ academic performance in …show more content…
The introduction letter will be presented at the schools to obtain permission for the administration of the questionnaire, as well as for the extraction of the results of students from records. The administration of the questionnaire will be done directly by the researcher with the aid of three research assistants who will be briefed on how to go about the exercise. After the questionnaires are filled by the respondents, they will be retrieved on the spot and kept away for …show more content…
Statistical Package for Social Science (SPSS) software will be employed for the analysis. The researcher will employ the use of percentages and frequencies for demographic data, while mean scores and standard deviation will be used to answer the research questions. Hypotheses one will be tested using multiple linear regression (Being a test of relationship between two independent variables and the dependent variable). Hypotheses two and three will be tested using linear regression analysis (Being a test of relationship between one independent variable and the dependent variable). Hypotheses four and five will be tested using t-test statistic (Being a test of significant difference between two sets of measurement). Hypotheses six will be tested using Analysis of Variance (ANOVA) (Being a test of significant difference between more than two sets of
To make this a fair test, we need to keep the same all variables that
4) Repeat this same test three time in order to gather and average later on.
Regression analysis is also used to understand which among the independent variables are related to the dependent variable, and to explore the forms of these relationships. In restricted circumstances, regression analysis can be used to infer causal relationships between the independent and dependent variables. However this can lead to illusions or false relationships, so caution is advisable;[2] for example, correlation does not imply
To research this hypothesis, I would use aspects of a descriptive study, relying heavily on a question-and-answer format. The data would be dependent on the responses of the subjects.
Identify the chosen research method (experimental, survey, observation or correlational research) and if appropriate, the design used. (1 mark) I am using a lab experiment as my research method. I am using an independent groups design. PB4: Identify the advantages(s) and disadvantage(s) of the chosen research method. (2 marks)
..., as well as the control, no picture, would be tested, a total of twenty trials, with four trials per picture during the subject’s test. The pictures were named Picture A, Picture B, Picture C, and Control. Then, the data gathered would be examined for similarities and differences with the picture shown, and the data would reveal whether the pictures influenced what the person saw in the inkblots. The independent variable of this test would be the pictures shown to the subjects before the test, and the dependent variable would be what was seen in the inkblots during the tests. There were four levels of independent variables including no picture, the control. The computer the test was taken on would be kept constant, the order of the slides shown, and the order of the pictures shown before the test. These factors are all needed in the experiment for clear data.
The authors of this article have outlined the purpose, aims, and objectives of the study. It also provides the methods used which is quantitative approach to collect the data, the results, conclusion of the study. It is important that the author should present the essential components of the study in the abstract because the abstract may be the only section that is read by readers to decide if the study is useful or not or to continue reading (Coughlan, Cronin, and Ryan, 2007; Ingham-Broomfield, 2008 p.104; Stockhausen and Conrick, 2002; Nieswiadomy, 2008 p.380).
The tennis ball is the constant variable factor (the variable that is kept the same, to make the investigation valid). The ball will dropped from increasing heights (cm-25, 50, 75,100,125,150,175,200) and the bounce of the ball will be measured. A sample size of 3 results will be taken from each height the ball is dropped. The same investigation will then be repeated, but one of the independent variables will be changed.
In our experiment, we are testing the affects sodium has on our blood pressure. If increased amounts of sodium are consumed, will that increase blood pressure? The hypothesis is when more sodium is introduced and consumed, then the person's blood pressure will increase, when blood pressure is a function of sodium. Our independent variable is different amounts of sodium introduced to noodles. We are using different amounts of sodium added which would be: 1 gram, 3 grams, 5 grams, and 7 grams. Our dependent variable is the diastolic and systolic readings will increase. The control in our experiment is our test subjects eating no noodles. The constants would be the same person taking the blood pressure, same three guys eating the food, the test subjects are all 17, and the same food with added sodium fed to each person in each trial. In this experiment, the first step we would took in this was acquiring three guys that are all 17 . One person would get high amounts of sodium, another person would have medium, and one person with very low amounts of sodium, our control. Then, we would take each person blood pressure and record it. After that we would give each person their assigned amount of sodium. Lastly, we would take the blood pressure of each person after they ate the different sodium foods. We will do this for two weeks three times a week and record our data and at the end compare our data. The materials we will need
Working with the Hypothesis involves the processes of look at both the data collected and the test results and if it confirms the hypothesis. (Salkind, 2012)
The two questions were designed to provide useful information. The respondents who are female and age between 18-24 or 25-35 contributed to the research. Others were seen as invalid questionnaires. The third section is the most important section of the questionnaire. There were ten closed questions in the third section which follow an easy to hard order, but eight of them were single answer questions whereas the rest two were multiple choice questions.
In order to obtain an A in this examination, students will demonstrate an in-depth understanding of each of the analyses. These analyses will typically include at least one of the more complex analyses (e.g., M...
d. high scores on the x variable are associated with low scores on the y variable.
Analysis of variance (ANOVA) is a collection of statistical models used in order to analyze the differences between group means and their associated procedures. In the ANOVA setting, the observed variance in a particular variable is partitioned into components attributable to different sources of variation. The following equation is the Fundamental Analysis-of-Variance Identity for a regression model.
