hi i'm teacher reddy welcome to another tech vlog for practical research too for today's topic we're going to learn the different kinds of variables used in quantitative research for this topic here is the most essential learning competency that you need to master your words [Music] one of the aspects of research is to describe and explain verbs that's why it is called the central concept of conducting research but do you know what is a variable the verbal is a measurable characteristics the changes in the volume is anything that may assure very numerical or categorical values for instance gender is a verbal it may be a male or a female but it won't be applicable as a variable if the setting of the research is an exclusive school for girls [Music] a variable can be classified as continuous or discrete variable a continuous variable is any variable that can take infinite number on the value that can occur within a population the values can be divided into fractions for example age height and temperature while this current variable is also known as the categorical or classificatory volume it is in a variable that has a limited number of distinct values in which cannot be divided into fractions for example we have sex blood group and number of children in the [Music] or decimals halimbawa in temperature composition means volume temperature now point five point seven point nine eight continuous verbal can be further classified into two types we have interval variable where it is in a variable that is a measurement where the difference between two values this had meaning example we have temperature on the other hand ratio variable possesses the properties of interval variable and has a clear definition of zero indication that there is none of that variable for example we have height weight and distance discrete variables can also be further classified into two types we have nominal variable it is any variable with no quantitative value it is two or more categories but does not imply ordering of cases like i cover business type and religion while original variable is in a variable that has two or more categories which can be ranked for example we have level of performance level of satisfaction educational highest to lowest or lowest to highest lagging variables a variable can be also be classified as independent or dependent variable independent variable is the cause variable or the one responsible for the conditions that act on something else to bring out changes while dependent variable is called the outcome variable where it is the result or effect of the changes brought by another variable ebics being undergo constant change i am independent variable at an effect dependent variable let's try solving these examples this is our test figure out the independent independent variables in the following situation first situation a soap manufacturer wants to prove that their detergent powder works better to remove puff stains our first step here is to list all the vulnerables that we can observe on the situation so we have one branch of detergent powder next is visibility of the stain so in this example our independent verbal is the brand of detergent powder and the changes that affects with the brand is the visibility of the stain that's why it is the dependent variable another situation you want to study the health benefits of walking so we have our variables occurrence of diseases and how often you walk a week so our independent variable is how often you want a week and the dependent variable is the occurrence of diseases because the number of times you walk affects the occurrence of diseases in your body that's why it is the dependent variable thank you very much for learning with me today i enjoy learning with you i am teacher randy happy to serve [Music] [Applause] you
