Regression analysis is a statistical procedure for developing a mathematical equation that describes how?
one dependent and one or more independent variables are related.
A procedure used for finding the equation of a straight line that provides the best approximation for the relationship between the independent and dependent variables is the?
Least Squares method
What is the difference betwene simple linear regression and multiple regression?
Simple linear regression is performed between one independent variable and one dependent variable. Multiple regression is performed between more than one independent variable and one dependent variable. Multiple regression returns results for the combined influence of all IVs on the DV as well as the individual influence of each IV while controlling for the other IVs. It is therefore a far more accurate test than running separate simple regressions for each IV. Multiple regression should not be confused with multivariate regression, which is a much more complex procedure involving more than one DV.
It has to do with the accuracy and precision of a measurement procedure?
Reliability!
A planned procedure to test a hypothesis is called bias?
No, it is not.
Regression analysis is a statistical procedure for developing a mathematical equation that describes how?
one dependent and one or more independent variables are related.
What are the definition between indeoendent and dependent variables?
The independent variable determines the value of other variables and is change by the person doing the experiment. The dependent variable is what is affected by the independent variable; it "depends" on the independent variable.
What needs to be on a science fair project?
Hypotheseis Procedure Materials Problem Question controls Independent variable Dependent variable Data Graphs Conclusion
A procedure used for finding the equation of a straight line that provides the best approximation for the relationship between the independent and dependent variables is the?
Least Squares method
What are the dependent and independent variables in a fruit and nut chocolate bar?
Your question isn't valid because you need an experimental procedure in place before you determine the variables.
What is a set of rules for performing a mathematical procedure called?
An algorithm, perhaps.
How do you calculate roots?
The roots of an equation in two variables is calculated by setting the dependent variable, y, equal to 0 and then solving the resulting equation for the independent variable, x. The procedure for solving the equation in x will depend on the nature of the equation.
A mathematical procedure used in vector graphics to describe curved paths is called?
Bezier
What is a definition for math algorithim?
It is a step-by-step procedure for carrying out some mathematical process.
How do you choose the most appropriate statistical procedure?
To choose the appropriate statistical test, the following four question must be answered; What are your dependent and independent variables? What is scale of measurement of the variables? How many groups/samples are there in the study? Have I have met the assumptions of the statistical test?
What are the importance of office procedure?
to let people gain skills and knowledge
Linear regression is a mathematical procedure that calculates a best fit line through the data It is called a best fit line because the parameters of the line will minimizes the sum of the squared?
It will minimise the sum of the squared distances from the points to the line of best fit, measured along the axis of the dependent variable.
