- 9. z Data - a set of information or observations under study. Data gathered from a population or a sample. Data may be classified as quantitative or qualitative
- 10. z Qualitative - are data which can assume values that manifest the concept of attributes. - can be taken on non-numerical values such as name of colors, labels and others. ( Categorical ) Example Flavor of ice cream Sizes of t-shirt ( large, medium, small )
- 11. z Quantitative - are data which are numerical in nature. ( Numerical ) Example 1. Hours of sleep 2. Number of students in Don Carlos Ledesma National High School.
- 13. z Variable - it is a characteristics of a population or a sample which makes the members different from each other. - variables can be discrete or continuous..
- 14. z Discrete variable - is a variable whose values are obtained through the process of counting. ( Counted ) Example Number of chairs in the classroom The number of teachers in the school The number of pots in the hallway.
- 15. z Continuous variable ā is a variable that can be obtained through the process of measuring. ( Measured ) Example Weight Height The distance between your house and school.
- 17. z 1. What is statistics? 2. What is the difference between qualitative and quantitative data? 3. How do you differentiate discrete and continuous variable? ANALYSIS
- 18. z Abstraction Statistics - is a scientific body of knowledge which deals with the collection, organization, presentation, interpretation, and analysis of data. Qualitative - are data which can assume values that manifest the concept of attributes. - can be taken on non-numerical values such as name of colors, labels and others. Quantitative - are data which are numerical in nature. Qualitative is categorical while Quantitative is numerical.
- 19. z Discrete variable - is a variable whose values are obtained through the process of counting. Continuous variable - is a variable that can be obtained through the process of measuring. Discrete variable is counted while Continuous variable is measured.
