What is meant by errors in prediction?
a) Inaccuracies in forecasting future outcomes
b) Fluctuations in the data
c) Variations in the sample
d) Outliers in the dataset

Compare with deviation scores?
a) Error in prediction is similar to deviation score
b) Deviation scores measure the accuracy of predictions
c) Deviation scores and errors in prediction are unrelated
d) both a and c

What is meant by the standard error of the regression line?
a) It measures the accuracy of the predictions made by the regression line
b) It shows the spread of data around the regression line
c) It is the same as the standard deviation
d) It represents the average error in the predictions made by the regression line

Compare with the standard deviation as a measure of variability.
a) Standard error of the regression line and standard deviation are the same
b) Standard error of the regression line measures the error in predictions while standard deviation measures the spread of data
c) Both the standard error of the regression line and standard deviation measure the accuracy of predictions
d) Standard deviation is used for linear regression while standard error is used for other regression methods
