Correlation and Regression 2
This Quiz contains MCQs about Correlation and Regression Analysis, Multiple Regression Analysis, Coefficient of Determination (Explained Variation), Unexplained Variation, Model Selection Criteria, Model Assumptions, Interpretation of results, Intercept, Slope, Partial Correlation, Significance tests, OLS Assumptions, Multicollinearity, Heteroscedasticity, Autocorrelation, graphical representation of the relationship between the variables, etc. Let us start MCQs about Correlation and Regression Analysis.
Correlation is a statistical measure used to determine the strength and direction of the mutual relationship between two quantitative variables. The value of correlation lies between $-1$ and $1$. The regression describes how an explanatory variable is numerically related to the dependent variables.
Both of the tools are used to represent the linear relationship between the two quantitative variables. The relationship between variables can be observed either using graphical representation between the variables or numerical computation using appropriate computational formula.
Note that neither regression nor correlation analyses can be interpreted as establishing some cause-and-effect relationships. Both of these can be used to indicate only how or to what extent the variables under study are associated (or mutually related) with each other. The correlation coefficient measures only the degree (strength) and direction of linear association between the two variables. Any conclusions about a cause-and-effect relationship must be based on the judgment of the analyst.
Good questions but what are the answer
Dear Belsti, when you will submit the quiz you will get the answers of all MCQS, however, if you don’t get any answer page, it means you need to update your internet browser or use another browser.
Thanks for visiting and liking my work.
knowledgeable materials
Thank you. Keep visiting and sharing itfeature.com
best and knowledge gaining
Really helpful
as I think You should explain the answers too.
great and good for revision
Informative but if you add reference of answers, it will be appreciable
Salam Sir,
Sir l am going to appear in lecturer test therefore I need your kind help
Please share some books for FPSC test.
Quite informative and good source of quick learning and assessing one’s self…
