measurement scales
Measurement scales are ways to classify and quantify data in research and statistics. There are four main types: 1. **Nominal**: categories without inherent order (e.g., types of fruit). 2. **Ordinal**: categories with a meaningful order but no consistent difference (e.g., rankings in a competition). 3. **Interval**: ordered categories with consistent differences but no true zero (e.g., temperature in Celsius). 4. **Ratio**: like interval but with a true zero, allowing for meaningful ratios (e.g., weight). Understanding these scales helps determine how to analyze data and draw conclusions from it.

Measurement scales are ways to categorize and quantify data. There are four main types: 1. **Nominal**: Labels or names without any order (e.g., types of fruits). 2. **Ordinal**: Ranks items in order (e.g., a satisfaction survey). 3. **Interval**: Measures with equal distances between values but no true zero (e.g., temperature in Celsius). 4. **Ratio**: Like interval, but has a true zero, allowing for meaningful comparisons (e.g., weight). Understanding these scales helps in organizing data and choosing the right statistical methods for analysis.

Measurement scales are systems that categorize and quantify data. There are four main types: 1. **Nominal**: Labels or names without a numeric value (e.g., types of fruit). 2. **Ordinal**: Ranks data in order but does not specify the difference between ranks (e.g., movie ratings). 3. **Interval**: Measures differences between values, but lacks a true zero point (e.g., temperature in Celsius). 4. **Ratio**: Similar to interval but has a true zero, allowing for comparison of absolute values (e.g., weight). Understanding these scales helps in choosing the right methods for data analysis and interpretation.
