Lesson Transcript
Instructor: Yuanxin (Amy) Yang Alcocer

Amy has a master's degree in secondary education and has taught math at a public charter high school.

Watch this video lesson to find out the difference between saying you have seven apples and saying that those apples are delicious. You will learn about quantitative data and why it is useful.

What Is Quantitative Data?

What's the difference between having seven apples and saying that they are delicious? Well, for one, we can count or measure the seven apples, but we can't put a number to how delicious they are. Those apples might be delicious to one person and be completely sour to another person.

What does this have to do with quantitative data? It has everything to do with quantitative data because it shows you what is considered quantitative data and what is not. Saying you have seven apples, because they can be represented numerically, is a piece of quantitative data. But, saying that they are delicious is not because you can't write that using numbers.

There are two types of data that quantitative data covers. They are data that can be counted and data that can be measured. Let's talk about what each data type looks like.

Data That Can Be Counted

Another way of saying that the data can be counted is to call it discrete data. Having the seven apples, for example, is discrete data because you can count seven apples. If you were to count the number of apples each tree produced in an apple orchard, that data is quantitative since the apples can be counted.

Other examples of discrete data include the number of girls in a math class, the number of boys who come to eat ice cream at three pm, and the number of kittens that a particular mom cat has. All of these are discrete and quantitative data because they can be represented by a mathematical number, and you can physically count them.

Data That Can Be Measured

Quantitative data is also data that you can measure. In math lingo, this is called continuous data. The weight of seven apples is continuous data because you can put the apples on a scale and weigh or measure them.

Other examples of continuous data include the height of your mom, the length of a football field, and the weight of a wolf. All of these are continuous data because you can measure them and represent them in a numerical manner.

Uses of Quantitative Data

All this information is very useful. What can you do with all this quantitative data? You can turn a collection of quantitative data into a report. By counting the apples of each apple tree in an orchard, you will be able to pinpoint any problems the orchard has. If some trees are not producing, you can locate them and find out why. If all the trees are producing very little, you can start to figure out what the orchard is doing wrong. And, if all the trees are producing a lot, you can find out what the orchard is doing right. Without quantitative data, you wouldn't know any of this.
