A) Ethnic origin of a candiate for public office
B) Score (0-100) on a placement examination
C) Fast-food established preferred by a student (mds, Burger King, or subway)
D) Mercury concentration in a sample of tuna
Identify each variable as continuous or discrete:
A) Number of homocides in Vancouver during one-month period
B) lenght of time between arrivals at an outpatient clinic
C) Number of typing errors on a page of manuscript
D) Number of defective lightbulbs in a package containing four bulbs
E) Time required to finish an examination
Solution
So based on the above definitions, the following are:
A) Ethnic origin of a candiate for public office - Qualitative
B) Score (0-100) on a placement examination - Quantitative
C) Fast-food established preferred by a student (mds, Burger King, or subway) - Qualitative
D) Mercury concentration in a sample of tuna - Quantitative
Identify each variable as continuous or discrete:
A) Number of homocides in Vancouver during one-month period - Discrete (cannot be a fraction, dead would be either 4 or 5 cannot be 4.5 dead unless it is the monthly average for a year)
B) lenght of time between arrivals at an outpatient clinic - Continuous (the time can be even fraction)
C) Number of typing errors on a page of manuscript - Discrete (cannot be a fraction, mistakes would be either 34 or 35, cannot be 34.5 mistakes unless it is the average mistakes per page across manuscript)
D) Number of defective lightbulbs in a package containing four bulbs - Discrete (Cannot be a fraction, a bulb will be either defective or not)
E) Time required to finish an examination - Continuous (it can be any period of time, even fraction is acceptable)
