1. KINDS OF VARIABLES AND ITS USES

2. Lesson objective: Differentiate kinds of variables and their uses – CS_RS12-Iac-c-3

3. What is a variable? it refers to the characteristics or attribute of an individual or an organization that can be measured or observed and that varies among people or organization being studied. the most common variables in social research are age, sex, gender, education, income, marital status, and occupation.

4. NOMINAL VARIABLES represents categories that cannot be ordered in any particular way. These are variables whose data are non-numeric labels that do not reflect quantitative information. EXAMPLES: gender, political affiliation, social status THE NATURE OF VARIABLES AND DATA

5. 2. ORDINAL VARIABLES represents categories that cannot be ordered from smallest to greatest. It refers to variables where there is a meaningful order or categories but there is no measurable distance between categories . EXAMPLES: grade level, sibling rank THE NATURE OF VARIAqBLES AND DATA

6. 3. INTERVAL VARIABLES values that lie along an evenly dispersed range of numbers. It is a variable whose data values are ranged in a real interval and can be as large as from negative infinity to positive infinity. EXAMPLES: Temperature, IQ Level THE NATURE OF VARIABLES AND DATA

7. 4. RATIO VARIABLES have values that lie along an evenly dispersed range of numbers when there is an absolute zero. EXAMPLES: enzyme activity, dose amount, reaction rate, flow rate, concentration, pulse, weight, length, temperature in Kelvin (0.0 Kelvin really does mean “no heat”), survival time THE NATURE OF VARIABLES AND DATA

8. KINDS OF VARIABLES Independent variables- those that probably cause influence or affect outcomes. They are invariably called treatment, manipulated, antecedent or predictor variables. Dependent variables- those that depend on the independent variables; they are outcomes of the influence of the independent variable. Intervening variable- “stand between” the independent and dependent variables and they show the effects, of the independent variable on the dependent variable.

9. KINDS OF VARIABLES 4. Control variables- special type of independent variables that are measured in a study because they influence the dependent variable. Researchers use statistical procedures (analysis of covariance{ANCOVA}) to control this variables. 5. Confounding variables- those that are not actually measured or observed in a study. They exist but their influence cannot be directly detected in a study.

10. Independent Assessment 1 Directions: Examine the given examples of research study and identify which is the IV- Independent Variable and the DV- Dependent Variables . Write your answer in another sheet of paper. 1. High School Students Study Habits and the Video Games They Play 2. Social Media in the Context of Fake News 3. Internet as the New Platform of Distance Learning Approach 4. Relevance of Mental Health amid the COVID 19 Pandemic 5. Social Amelioration Program on Non- Working Individuals during “Bayanihan Act of 2020”
