Variables of Quantitative research power point presentation

These are the list of variables used in research project

1. V a r i a b l e s o f Q u a n t i t a t i v e R e s e a r c h

2. V a r i a b l e Each person/thing we collect data on is called an observation. Such observation possesses a variety of characteristics, it could be the same for every member of the group and called constant

3. T y p e s o f V a r i a b l e s

4. I n d e p e n d e n t V a r i a b l e Variables that are manipulated or controlled or changed. It is what the researcher studies to see its relationship or effects (presumed possible cause).

5. T w o t y p e s o f I n d e p e n d e n t V a r i a b l e

6. Experimental independent variables - c a n b e directly manipulated by researchers . Subject variables cannot be manipulated by researchers, but they can be used to group research subjects categorically

7. D e p e n d e n t V a r i a b l e t h e dependent variable is a response variable or output. It is the factor that is observed and measured to determine the effect of the independent variable;

8. Control Variable Control variables are factors controlled by the experimenter to cancel out or neutralize any effect on the observed phenomenon. A single study cannot examine all of the variables in a situation or in a person; some must be neutralized to guarantee they will not exert different or moderating effects on the relationship between the dependent and independent variable.

9. Intervening Variable It is the factor that theoretically affect observed phenomenon but cannot be seen, measured or manipulated; its effects mustbe inferred from the effects of the independent and moderate variable in the observed phenomenon.

10. Confounding Variable Those that are not actually measured or observed in the study. They exist but their influence cannot be directly detected in the study.

11. A. Continuous Variable

12. 1. Interval Variables Values that lie along with an evenly dispersed range of numbers. It is a variable whose data values are ranged in the real interval and can be as large as from negative infinity to positive infinity.

13. 2. Ratio Variables Have values that lie along with an evenly dispersed range of numbers when there is an absolute zero.

14. B. Discrete Variables

15. Nominal Variables Represents categories that cannot be ordered in any particular way. These are variables whose data is non-numeric labels that do not reflect quantitative information.

16. Ordinal Variables Represents categories that could be ordered from smallest to greatest. It refers to variables where there is meaningful order or categories but there is no measurable distance between categories
