That is, what type of correlation is this? 4 _________ What is the predicted voltage for a current of 4 amps (for this calculation, presume that the relationship remains linear beyond 2 amps)? 5 _________ What is the predicted current for a voltage of 20 volts (for this calculation, presume that the relationship remains linear beyond 10 volts)? 6 _________ Calculate the linear correlation coefficient r for the the current and voltage. 7 _________ Is the correlation none, low, moderate, high, or perfect? 8 _________ Calculate the coefficient of determination. 9 __________________ What does the coefficient of determination tell us about the relationship between per the current and voltage? 10 __________________ Does the relationship appear to be a linear relationship between the current and voltage? 11 __________________ There are actually two functions involved, one being a linear component. Do you have any idea what the other function might be (nota bene: it helps if you took MS 101...).
