Preparing for a thesis defense 🍏Preparing for a thesis defense is an important step in the completion of your academic program. To ensure a successful defense, here are some steps you can take to prepare yourself: 👍Understand the requirements: Familiarize yourself with the specific requirements and guidelines for your thesis defense. Review your department's guidelines and any feedback provided by your advisor or committee members. 👍Revisit your thesis: Review your thesis thoroughly to ensure you have a clear understanding of its content, methodology, and findings. Identify the key points, arguments, and supporting evidence. 👍Anticipate questions: Prepare a list of potential questions that your committee members may ask during the defense. These questions can cover various aspects, such as the background and motivation for your research, the methodology employed, results obtained, and implications of your work. Practice formulating concise and coherent answers to these questions. 👍Practice your presentation: Create a concise and engaging presentation that summarizes your research. Pay attention to the structure, flow, and clarity of your slides. Practice delivering your presentation multiple times to ensure you stay within the allotted time and become comfortable with the material. 👍Seek feedback: Share your presentation and thesis with your advisor and colleagues for feedback. Incorporate their suggestions to improve the clarity and effectiveness of your presentation. 👍Conduct a mock defense: Organize a mock defense with your peers or colleagues. Ask them to play the role of committee members and provide constructive feedback. This exercise will help you simulate the actual defense and identify areas where you need to improve. 👍Prepare visual aids: Prepare any visual aids, such as charts, graphs, or diagrams, that can help illustrate your research findings. Ensure they are clear, visually appealing, and support your main points. 👍Address potential weaknesses: Reflect on any potential weaknesses or limitations of your research. Develop strategies to address them and be prepared to discuss them during the defense. 👍Stay updated: Be aware of recent developments in your field of study. Familiarize yourself with any relevant literature or studies published since the submission of your thesis. 👍Stay calm and confident: On the day of the defense, try to remain calm and composed. Take deep breaths, maintain eye contact, and speak clearly. Remember that your committee members are there to evaluate your work and provide feedback, not to intimidate you. 👍Be open to feedback: During the defense, listen attentively to the questions and comments from your committee members. Respond thoughtfully and respectfully, even if you encounter challenging or critical questions. Use feedback as an opportunity to demonstrate your knowledge and willingness to learn. 👍Follow up: After the defense, consider implementing any suggestions or revisions recommended by your committee members. If revisions are required, work diligently to address them in a timely manner.

Cutting/copying and pasting text or note from internet and using as your own work. 3. Purchasing someone's work and describing it as your own work. 4. Citing a source but reproducing the exact word/Statement without quotation marks. 5. Borrowing the structure of another author's phrases/sentences without giving the source. 6. Borrowing all or part of another paper. Note that plagiarism above 20% is not allowed for Masters thesis paper and above 35% is not permitted for PhD dissertation paper. Research designs + Research design is an arrangement of conditions for collection and analysis of data based on purpose of the study. + It constitutes the blue print for the collection, measurement and analysis of data aimed at answering specific research questions. + There are different research designs. + The selection of a research design depends on its purpose. + Some of commonly mentioned research designs are:        Qualitative Designs Phenomonology Ethnography  Historical            Quantitative Experimental Cross-sectional Cohort Explanatory Quasi-experimental Descriptive 1. Descriptive research design # It emphasis on determining the frequency with which something occurs or the extent to which two variables are correlated. # It tries to discover answers to the question who, what, when, where, and sometimes how. # It clearly describes a situation or behavior obtained at a particular time. 2. Explanatory research design @ It investigates whether the value of one variable causes or determines the value of other variable. @ It assesses relationship between variables in order to explain certain problems or events. @ It attempts go explain the reasons for the phenomenon. @ It uses theories or hypotheses to study about forces that  caused a certain phenomenon to occur. @ It focuses on relationship between variables. @ It uses different models of relationship. 3. Experimental research design = It focuses on testing the change of variables by considering at least two groups (both experimental. = It usually involves practical measurement of data using various methods. = It is based on the principle of randomization. That is, to be representative, experiments should be done on random samples. STATEMENT OF THE PROBLEM © Statement of the problem needs to discuss the practical problems that you have observed or get in the form of feedback concerning the topic that you are interested in doing the investigation. © In addition, you need to do an empirical review related to your topic and identify the gap that needs to be filled. Research gap/ literature gap @ It is based on review of theoretical and empirical literature. @ Research gap refers to: ® Unavailability of studies on the issue of the study. ® Presence of very few studies on the issue under study. ® Lack of outdated studies on the issue of study. ® Due to conflicting findings on the issue under investigation. ® Practical problems noticed in an entity with no explanation of it in the empirical studies. Conceptual framework Conceptual/theoretical framework of the study indicates the relationship   between variables. The conceptual framework should show a diagrammatically demonstration of the relationship between the Independent and dependent variables. የማማከር አገልግሎት እንሰጣለን

It seems there might still be a typo with "korthosis." Assuming you meant "kurtosis," here is an elaboration on how skewness and kurtosis are used in academic research: ### Skewness Skewness measures the asymmetry of a probability distribution. Here's how it is used in academic research: 1. Definition: Skewness indicates the direction and degree of skew: - Positive skew (right-skewed): The tail on the right side is longer. - Negative skew (left-skewed): The tail on the left side is longer. 2. Applications: - Economics and Finance: Used to analyze income distributions or the distribution of asset returns. For example, a positively skewed distribution of income suggests a large number of people earn below the mean income, with a few earning significantly above it. - Healthcare: Examines distributions of medical data such as response times, age at diagnosis, or recovery times. - Social Sciences: Analyzes survey data to determine the distribution of responses. 3. Interpretation: - Helps in understanding the nature of the data, particularly if it deviates from a normal distribution, which is important for choosing the right statistical tests and models. ### Kurtosis Kurtosis measures the "tailedness" of the distribution. It describes the shape of the distribution's tails in relation to its overall shape: 1. Definition: Kurtosis can be: - Leptokurtic: Distributions with heavy tails (more outliers). - Platykurtic: Distributions with light tails (fewer outliers). - Mesokurtic: Distributions similar to a normal distribution. 2. Applications: - Risk Management in Finance: High kurtosis in the return distribution of an asset indicates a higher risk of extreme returns. - Quality Control in Manufacturing: Ensures product measurements follow the expected distribution, identifying processes that might produce more outliers. - Psychometrics: Analyzes the distribution of test scores to ensure they align with expected distributions. 3. Interpretation: - Indicates the likelihood of outliers, which is crucial for assessing the robustness of statistical analyses and models. ### Use in Academic Research #### Data Analysis and Model Selection In academic research, skewness and kurtosis are used to understand the distributional characteristics of data. This understanding guides the selection of appropriate statistical methods and models. For example, data that are heavily skewed or have high kurtosis might require non-parametric methods or transformation before applying parametric tests. #### Examples of Research Utilization 1. Economic Studies: Researchers analyze the skewness and kurtosis of income distributions to understand inequality and the presence of outliers (extremely high incomes). 2. Medical Research: Studies often report the skewness and kurtosis of biological measures, like blood pressure or cholesterol levels, to assess whether the assumptions of normality hold. 3. Educational Testing: In psychometrics, test score distributions are examined for skewness and kurtosis to ensure fair assessments and the validity of test results. #### Statistical Reporting Academic papers often report skewness and kurtosis as part of the descriptive statistics. This reporting helps in: - Providing a complete picture of data characteristics. - Justifying the use of specific statistical techniques. - Interpreting the results within the context of data distribution. By understanding and applying skewness and kurtosis, researchers ensure more accurate data analysis, leading to more reliable and valid conclusions.

Kothari's "Research Methodology: Methods and Techniques" is a comprehensive guidebook widely used in academic research. This text covers the foundational principles and practical methods for conducting research in various fields. Here are some key concepts and components covered in Kothari's research methodology: ### Key Concepts 1. Research Design: - Definition: A framework for collecting and analyzing data. - Types: Exploratory, descriptive, and experimental research designs. 2. Sampling Design: - Definition: The plan for selecting a sample from a population. - Types: Probability sampling (random sampling, stratified sampling) and non-probability sampling (convenience sampling, judgmental sampling). 3. Data Collection Methods: - Primary Data: Data collected directly from first-hand sources. - Techniques: Surveys, interviews, observations, experiments. - Secondary Data: Data collected from existing sources. - Sources: Books, journals, reports, online databases. 4. Measurement and Scaling Techniques: - Measurement: The process of assigning numbers or labels to units of analysis. - Scaling: The process of creating a continuum on which measured objects are located. - Types of Scales: Nominal, ordinal, interval, and ratio scales. 5. Data Processing and Analysis: - Data Processing: Editing, coding, classification, and tabulation of data. - Analysis: Applying statistical methods to interpret data. - Descriptive Statistics: Mean, median, mode, standard deviation. - Inferential Statistics: Hypothesis testing, regression analysis, ANOVA. 6. Hypothesis Testing: - Formulation: Developing a null hypothesis (H0) and an alternative hypothesis (H1). - Testing: Using statistical tests to determine the likelihood that H0 is true. - Types of Tests: t-tests, chi-square tests, F-tests, and z-tests. 7. Report Writing: - Structure: Introduction, literature review, methodology, results, discussion, conclusion. - Presentation: Clarity, coherence, logical flow, proper citation. ### Additional Topics - Research Ethics: Ensuring the integrity and ethical standards in research. - Qualitative and Quantitative Methods: Understanding the differences and applications of qualitative (non-numerical data) and quantitative (numerical data) research. - Literature Review: Systematic assessment of existing research to frame the current study. - Problem Formulation: Defining the research problem clearly and precisely. Kothari’s methodology is celebrated for its detailed explanation of research processes, making it accessible to beginners and useful for advanced researchers looking to refine their methods.
