Lecture 2: Measurement Scales and its Types | Nominal - Ordinal - Interval and Ratio Scale 

In this video, we'll explore the fundamental concept of measurement scales in statistics, including the four main types: Nominal, Ordinal, Interval, and Ratio scales.
Topic Covered:
- What is a scale and scale of measurement?
- Nominal Scale: Definition, example, and explanation
- Ordinal Scale: Definition, example, and explanation
- Interval Scale: Definition, example, and explanation
- Ratio Scale: Definition, example, and explanation
Scale Definitions with Examples:
- Nominal Scale: Assigns labels or categories without order or hierarchy. Example: Gender (Male/Female)
- Ordinal Scale: Assigns ranks or orders with hierarchy, but unequal distances. Example: Education level (Dropout, High School, Bachelor's, Master's)
- Interval Scale: Assigns values with equal intervals, but arbitrary zero points. Example: Temperature in Celsius (0°C, 10°C, 20°C, ...)
- Ratio Scale: Assigns values with equal intervals, true zero points, and equal ratios. Example: Height (160cm, 170cm, 180cm, ...)
Key Takeaways:
- Understand the differences between each scale of measurement
- Learn how to identify and apply the appropriate scale for your data
- Enhance your statistical analysis skills with a solid grasp of measurement scales
