Identify the correct data type and level of measurement of the variables listed below by stating if they are qualitative, quantitative, discrete, continuous, nominal, ordinal, interval, and ratio.
a. Hair colour of women in the Open Campus
b. Weights of washing machines
c. types of sedans
d. time it takes to sing the National Anthem
e. total income for Economists in St. Lucia
f. body temperatures of seals in Antarctica
g. supervisors being rated as superior, above average, average, below average, or poor
a. Hair colour of women in the Open Campus
=> Data type is categorical and the level of measurement is Nominal and they are qualitative. Because hair color is describing quality of hair.
b. Weights of washing machines:
=>Weights are discrete because they are countable and quantitative in nature and level of measurement is Ratio.
c. types of sedans:
=>Types of sedans are categorical , qualitative and the level of measurement is ORDINAL.
d. time it takes to sing the National Anthem.
=> Variable is discrete and type of variable is quantitative and level of measurement is Ratio
e. total income for Economists in St. Lucia
=> Variable is discrete and type of variable is quantitative and level of measurement is Ratio.
f. body temperatures of seals in Antarctica
=> Variable is continuous (Because it is infinite measure) and type of variable is quantitative and level of measurement is Interval (because the zero points are arbitrary)
g. supervisors being rated as superior, above average, average, below average, or poor
=> Variable is categorical and type of variable is qualitative and level of measurement is ORDINAL( Because they are in order)
