📋 Operationalization of variables involves determining the type and scale of variables, as well as creating a table to define them.
🔢 Variables can be categorized as categorical (containing words or responses) or quantitative (containing numbers), which can further be classified as discrete or continuous.
🧮 Categorical variables can have two categories (dicotomous) or more than two categories (polychotomous), while quantitative variables can be discrete (whole numbers) or continuous (decimal numbers).
🔑 Variables in research can be quantitative, including continuous and discrete variables, or quasi-quantitative, which have an ordered hierarchy.
📊 Quantitative variables can be further classified into continuous variables, which can have decimal values, and discrete variables, which have integer values.
🔢 Quasi-quantitative variables have categories with an ordered hierarchy, such as levels of education, which can be represented numerically for statistical calculations.
📋 Variables in research can also be classified based on their scale: nominal, ordinal, interval, or ratio scales.
😊 Understanding the different types of variables and scales is essential for conducting accurate and meaningful research.
📊 Variables in social sciences research are often measured using scales, which provide a range for respondents to answer within.
🔢 Interval scales allow respondents to express their agreement or disagreement on a numerical scale, while ratio scales are used for quantitative variables that start from zero.
📝 In addition to defining the type and scale of a variable, researchers also need to provide a conceptual definition to ensure clarity and avoid misinterpretation.
:bulb: The video discusses the importance of defining variables in research and its operationalization.
:books: Researchers should use formal documents or reputable sources to define variables.
:pencil2: Citations and references are crucial in research papers, both in-text and bibliographic.
🔬 Variables in research are operationalized using measurement devices or instruments.
📏 Different fields use different measurement instruments to capture specific variables.
📝 Multiple variables can be measured using the same instrument, but each variable has its own operationalization.
💡 Citations are essential in academic writing to acknowledge sources and provide evidence for our statements.
📚 Citations should be placed at the end of a sentence or paragraph and indicate that the information is taken from another author.
🔎 Lack of citations can lead to errors and incomplete academic work, so it is important to always include proper references.
🔍 It is important to use appropriate citation styles, such as APA, when citing sources in research.
📚 There are different tools available, such as citation machines and Mendeley, to help with finding and properly citing information.
🎓 Understanding the different types of citations, including intra-documentary and bibliographic citations, is crucial for academic writing.
