The two main types of data are qualitative and quantitative. Qualitative data is descriptive and is usually expressed in words. Quantitative data is numerical and is often represented by numbers. Here are some examples of each type:
Qualitative data:
- Colors of cars in a parking lot
- Opinions of students on a new school policy
- Names of different types of fruits in a grocery store
Quantitative data:
- Height of students in a classroom
- Temperature in a room
- Number of books in a library
By understanding the difference between qualitative and quantitative data, we can better analyze and interpret data and make informed decisions.
