THE RESEARCH PROCESS

Distinguish between an independent and a dependent variable

Introduction

Independent and dependent variables are arithmetical tools used in a research to keep trail of what 's going on . They permit you to uphold control over your research in a quantitative way (Schwab , 2004 ,

. 65

Independent variable is a variable in an equation that may possibly have its value liberally chosen without taking into account values of any additional variable . A good illustration can be seen in an equation

such as y 8x - 4 , the independent variable is x . In an nutshell , an independent variable is a variable which can be assigned any allowable value with no any limit imposed by any additional variable (Austin Pinkleton , 2001 ,

. 79

A dependent variable on the other hand is a variable that depends on one or more other variables . If we go back to our equation y 8x - 4 , the dependent variable is y . The value of y depends on the value selected for x . It should be noted that a dependent variable is more often than not isolated on one side of an equation . In an nutshell , a dependent variable is a variable in an equation , function or expression that has its value dogged by the option of value (s ) of other variable (s (Schwab , 2004 ,

In calculus , the identification of the self-governing and reliant variable is important , in the sense that the rate of change , or copied of the reliant variable is designed with respect to the self-governing variable . Dependent and independent variables refer to values that alter in affiliation to each other . The reliant variables are those that are observed to alter in reply to the independent variables . The independent variables on the other hand , are those that are intentionally manipulated to appeal to a change in the reliant variables . For instance , if x is given then y occurs , where x stands for the independent variables and y stands for the dependent variables (Austin Pinkleton , 2001 ,

While independent variables are also identified as forecaster variables controlled variables , descriptive variables , regressors , manipulate variables or input variables reliant variables on the other are also identified as the regress variable , the experimental variable , the responding variable , the result variable , the output variable , just to mention but a few (Schwab , 2004 ,

Conclusion

In an experimental research , the investigator manipulates at least one variable and subsequently measures at least one result . Manipulated variables are termed as self-governing variables while outcome variables are termed as dependent variables

A self-governing variable is a variable whose value determines the value of additional variables . The dependent variable depends on the result of the self-governing variables

Name and define the measures of central tendency and of variability

Introduction

Central tendency is an arithmetical measure that identifies a particular score as envoy of a whole distribution of scores . The objective is to discover the single score that is the most envoy of the whole distribution . Unluckily...
