A variable that is both (1) mutually exclusive, (2) exhaustive, (3) has a rank order AND (4) has equal distance between categori
es (i.e., usually continuous variables without a true zero like Fahrenheit temperature readings -- the difference between 18 & 19 is the same as between 75 and 76) are called _______________ variables. a) interval
b) ordinal
c) nominal
d) ratio
<em>An interval variable which is also refereed to as ordinal variable with the additional property that t has differences in magnitudes of the between two meaningful values</em>
<em>An example of an interval variable is ,when a temperature of 90 degrees and 100 degrees is the same difference as between 90 degrees and 80 degrees.</em>
<em>Interval variables are also said to be mutually exclusive , exhaustive and also having a rank or ranking order.</em>
if 600 people were surveyed it means that 10% equals 60 since 60x10=600. Since we now know that 10% is 60, this would mean that 20% is 120. meaning that 120 people took the bus
