QUESTION 1
Levels of measurement
a. Number of bedrooms: This is a ratio type of measurement. This is because it has
a true zero. That is, having zero number of bedrooms does not mean any other
thing other than there is no bedroom. Compare this, in some data, like in a likert
scale, zero could mean a different thing.
b. Number of bathrooms: This is also a ratio measurement as it has a true zero.
c. Dishwasher (yes or no): This is a nominal variable as it has no quantitative value.
d. Walking distance (in minutes): This is a ratio type of measurement. This is
because it has a true zero. Zero minutes means no distance walked.
e. Total travel time in minutes: This is a ratio type of measurement. This is because
it has a true zero. Zero minutes means no travel.
f. Rent per week: This is a ratio type of measurement. This is because it has a true
zero. There is no zero rent.
