what is meant by independent and dependent variable as
it pertains to correlation? Provide an example how do we
quantitatively measure the strength of correlation between the two
variables?
Regression and Correlation Analysis
Use the dependent variable (labeled Y) and one of the
independent variables (labeled X1, X2, and X3) in the data file.
Select and use one independent variable throughout this analysis.
Use Excel to perform the regression and correlation analysis to
answer the following.
Generate a scatterplot for the specified dependent variable (Y)
and the selected independent variable (X), including the graph of
the "best fit" line. Interpret.
Determine the equation of the "best fit" line, which...
Explain the difference between two independent samples and two
dependent samples.
Provide examples of each type of pairs of samples.
Compare and contrast the hypothesis testing process of two
independent and two dependent samples. (Do not conduct the
hypothesis testing.)
