Corelation and Regression

the x-variable

the independent variable

the predictor variable

all of the above (a-c) are correct

Ordinal

Interval

Nominal

Ratio

0 and 1

1 and 0

1 and 1

None of these

the sign of the slope will change

the magnitude of the slope will change

both a and b are correct

neither a nor b are correct

Regression

Correlation

Skewness

All of these

there is evidence that x causes a change in y

there is evidence that y causes a change in x

there might not be any causal relationship between x and y

None of these alternatives is correct.

the exact value of the response variable can be computed

the computed response to the independent value will always give a minimal residual

the computed value of y will always be the best estimate of the mean response

none of these alternatives is correct.

must have a positive slope

must have a negative slope

could have either a positive or a negative slope

must have a positive y intercept
