QUESTION:
Refer to the Baseball 2009 data, which report information on the 30 Major League Baseball teams for the 2009 season. Consider the following variables: number of wins, team salary, season attendance, whether the team is in the American or National League, and the number of home runs hit. a. Which of these variables are quantitative and which are qualitative? b. Determine the level of measurement for each of the variables
ANSWER:Step 1 of 3
Categorical/qualitative variables place the individuals into a category, while a quantitative variable is a numerical variable.
The level of measurement is nominal, if the values of the variables can only be named and not ordered.
The level of measurement is ordinal, if the values of the variables can be named and ordered, but the difference between two values has no meaning.
The level of measurement is interval, if the difference between two values has a meaning, but the variable contains no absolute zero.
The level of measurement is ratio, if the variable contains an absolute zero.
