Answer: 5
Step-by-step explanation:
Answer:
numerator degree of freedom = 3
Denominator degree of freedom = 47
Step-by-step explanation:
The numerator degree of freedom is given by :
p - 1 ; where p = number of predictors ;
p = number of independent variables + 1
Number of independent variables = 3
p = 3 + 1 = 4
Numerator degree of freedom = p - 1 = 4 - 1 = 3
The denominator degree of freedom = n - p ; where n = number of observations
Number of observations, n = 51
Denominator degree of freedom = n - p = 51 - 4 = 47
Answer: c. Nominal
Step-by-step explanation:
Level of measurement determines the nature of description .
The four levels of measurements scales are
1. Nominal scale
- Categorize the data on the basis of the quality such as Gender, color, etc.
2. Ordinal scale
- Order attributes according to their ranks. For example : 1 < 2 < 3 .
3. Interval scale
- Describe the feature of the difference between any two categories. For example : Fahrenheit scale to measure temperature.
4. Ratio scale
- Consist of the features of nominal, ordinal, and interval measures but in includes a "true zero" point.
For example : Age.
∴ A<u> nominal</u> variable is a qualitative variable such that there is no meaningful ordering or ranking of the categories.
Hence, the correct answer is c. Nominal .
