Ch 3 Ivy Software Business & Math Stats ACTUAL UPDATED QUESTIONS AND
CORRECT ANSWERS
regression analysis method of forecasting, not limited to predicting unknown variable solely from
historical levels of that same variable but is able to predict based on
y=what forecaster wishes to predict, dependent variable
x=which forecast depends, independent variable
coefficient of determination how much variation about mean line
variable you are trying to predict with regression analysis false-dependent variable
is referred to as the independent variable. true or false
regression analysis attempts to find the line through a true
scatter of data points which decreases the sum of the
squared deviations of the points from the line. true or
false
the coefficient of determination is the unexplained false explained/total
variation divided by total variation. true or false
