WEEK 2 Flashcards
of measurement use to assign numbers to objects where different numbers indicate different objects into discrete categories.
MEASUREMENT SCALES
Nominal Scale
is categorize data in natural order, also assign numbers (like nominal), but here the numbers also have meaningful order.
MEASUREMENT SCALES
Ordinal Scale
Numbers have order, but there are also equal intervals between adjacent categories or have an order difference between categories is identical.
MEASUREMENT SCALES
Interval Scale
The difference are meaningful, plus ratios are meaningful and there is a true zero point.
MEASUREMENT SCALES
Ratio Scale
It refers to the practice of categorizing and classifying data to make it more usable. It refers to the arrangement of figures in such a form that comparison become easy and conclusion can be drawn.
Organization of Data
When data are classified on the basis of location or areas.
4 TYPES OF CLASSIFICATION OF DATA

4 TYPES OF CLASSIFICATION OF DATA
Qualitative Classification Data
Refers to the classification of data according to some characteristics, which can be measured such as height, weight, income, profits, etc.
4 TYPES OF CLASSIFICATION OF DATA
Quantitative Classification
Distribution is one in which the data can only take on certain values, for example integers.
Types of Quantitative Classification of Data
Discrete Frequenc y
Distribution is one in which data can take on any value within a specified range (which may be infinite).
Types of Quantitative Classification of Data
Continuous Frequency
Refers to the characteristics that varies in magnitude quantity.
Elements of Quantitative Classification of Data
Variables
Refers to the number of times each variable gets repeated.
Elements of Quantitative Classification of Data
