-
Each child's gender
-
His or her favorite color
-
Whether he or she owns at least one pet
-
How he or she gets to and from school
You can identify qualitative data by noticing that it links an attribute — that is, a quality — to each member of the data set. For example, four attributes of Emma are that she's female, her favorite color is green, she owns a dog, and she walks to school.
On the other hand, quantitative data provides numerical information — that is, information about quantities, or amounts. For example, quantitative data on this same classroom of students can include the following:-
Each child's height in inches
-
Each child's weight in pounds
-
The number of siblings each child has
-
The number of words each child spelled correctly on the most recent spelling test
You can identify quantitative data by noticing that it links a number to each member of the data set. For example, Carlos is 55 inches tall, weighs 68 pounds, has three siblings, and spelled 18 words correctly.
