A numerical characteristic of a population is known as a parameter, which summarizes a specific aspect of the population's attributes. Common examples include the population mean (average), population variance, or population proportion. These parameters provide valuable insights into the overall behavior and distribution of the population being studied. For example, the mean income of a city's residents is a numerical characteristic that reflects the economic status of the population.
They have the same form for any variables, but the numerical coefficients can be different.
Either.
Population Parameter
The answer is Statistics
It is a characteristic that is being studied which is different for different members of the population. The characteristic need not be numeric and the population need not be people - for example, you could be studying the colour of cars.
parameter
You need numerical data on some characteristic of a population.
characteristics of numerical computing
Non-numerical nominal characteristics can be the brands of cars we drive, the names of cities were we live, our race, religion, etc. Numerical nominal characteristics can be area codes, zip codes, numbers on the back of jerseys of basketball players. Numerical, non-nominal data is someone's weight or height.
physical quantities have numerical magnitude and unit
Parameter
They have the same form for any variables, but the numerical coefficients can be different.
A parameter is a numerical measurement of a population; a statistic is a numerical measurement of a sample.
Categorical
Favorite color is qualitative data because it represents a characteristic or quality, rather than a numerical value. It cannot be measured or quantified in a numerical sense.
Either.
