ex post facto) ccompare two groups that differ on the independent variable (e.g., gender) on the dependent variable (e.g., examination malpractice). A researcher cannot manipulate a person's gender, so instead males and females are compared on their examination malpractice behavior. Lesson Summary So now, the scientific version of our first sentence will read like this, 'A researcher manipulates the independent variable with the goal of measuring changes in the dependent variable, while accounting for and controlling confounding, extraneous and moderator variables by using control variables.'. Ah, the bane of developing 'good' category codes! Therefore, once the general research topic has been identified, the researcher should identify the key variables of interest. It's easy to confuse the " independent variable itself " with its "levels!" In other words, it would be wrong to say, "The independent variable in the preceding example is the hands-on method of science instruction." That's only part of it! Therefore: it is variables that we will be focusing our main attention on in research questions/problem statements - and collecting data (information) on them - and looking at how they 'vary' to answer our research questions! For example, if you are investigating the relationship between corporate environmental sustainability efforts the independent variable and dependent variables associated with measuring employee satisfaction at work using a survey instrument, you would first identify each variable and then provide background information about the variables. Then you'll know whether it is "discrete" (categorical) or "continuous" (same name!) Just to review and practice: When we defined 'type of school' by its 'raw value or 'exact current school population that would be ratio scaled (possible 'true zero school still under construction. Dependent variable: ul li Number of paper clips picked up number of paper clips observed and counted (measured).

Instructions of what to do, moderator variables are variables that can increase or decrease the relationship between the independent and dependent variables. Correlational: Describes the relationship between variables. For example, the researcher needs to identify specific variables that define literacy: reading fluency (the ability to read a text out loud reading comprehension (understanding what is read vocabulary, interest in reading, etc. Please note, from the preceding example, that I thought up an "overall descriptive label " for the independent variable itself : " Method of Instruction." Next, I identified each of its "levels; " that is, how many subgroups are contained within. In our original example of hungry people throwing the ball, there are several confounding variables we need to make sure we account for. Graphic Tutorial ; Case Example for Independent and Dependent Variables. That's because it stays exactly the same for each and every student (research subject; research unit)! In the methods section, you build on the literature review of prior studies about the research problem to describe in detail background about each variable, breaking each down for measurement and analysis. For example, a descriptive study might examine teachers' knowledge of literacy development. In our ball throwing example, if you secretly placed a research assistant - someone who works for you - among the participants and made them complain loudly about how bad they're failing, this would likely make everyone else's ball throwing worse. Next, return to Educational Research Steps, copyright 2012, Katrina. It might be thought of as the outcome.
Dependent variables are the " target outcomes the ones you expect to change as a result of the independent variables. Descriptive studies are the most simple research design and provide the least amount of information about improving education.
