Q2.2 - Elementary Statistics

Question

Explain the meaning of 

a) Qualitative Variable 

b) Discrete, Quantitative Variable 

c) Continuous, Quantitative Variable 

Step-by-Step Solution

Answer

Qualitative can't be measured in numbers, Discrete Quantitative can be measured only in whole numbers, Continuous Quantitative Variable can be measured in both whole & non whole numbers. Step 1 : Basic Definitions

Step 1 : Qualitative Variable

Qualitative Variable is a variable that can't be measured in numerical units. 

Examples are - Level of honesty, Intensity of love etc 

Step 2 : Discrete Quantitative Variable

Quantitative Variables can be explained in numerical units 

• Discrete Quantitative Variable can be measured only whole numbers (non fractional & non decimal) 
• Quantitative Discrete examples are - Number of people (can be only 1,2,3...) ; & numbers on die (1,2,3,4,5,6) 

Step 3 : Continuous Quantitative Variable

Quantitative Variables can be explained in numerical units

• Continuous Quantitative Variable can be measured in both whole & non whole (fractional & decimal) numbers. 
• Quantitative Continuous Variables are - Weight & height of people, which can be in form of 45.3 kg & 5.5 inch respectively.
