What are meristic traits examples?
Meristic traits are those in which the phenotypes are recorded by counting whole numbers. Examples of meristic traits include the num- ber of seeds in a pod or the number of eggs laid by a chicken in a year. These are quantitative traits, but they do not have an infinite range of phenotypes.
What is derived variable?
Derived variables are variables that are created from other variables using an expression. For example, you might create a numeric derived variable to show the sum of the values stored in two or more other numeric variables.
What are interval variables?
An interval variable is a one where the difference between two values is meaningful. The difference between a temperature of 100 degrees and 90 degrees is the same difference as between 90 degrees and 80 degrees. When the variable equals 0.0, there is none of that variable.
Is gender a nominal?
Gender is an example of a nominal measurement in which a number (e.g., 1) is used to label one gender, such as males, and a different number (e.g., 2) is used for the other gender, females. Numbers do not mean that one gender is better or worse than the other; they simply are used to classify persons.
What is meristic variation?
numerical variation in taxonomic characters such as numbers of bristles, vertebrae, spots etc.
What are meristic counts?
Meristics is an area of ichthyology which relates to counting quantitative features of fish, such as the number of fins or scales. A meristic (countable trait) can be used to describe a particular species of fish, or used to identify an unknown species.
What is difference between discrete and continuous variable?
A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A discrete random variable X has a countable number of possible values.
What is interval data example?
Interval data is measured on an interval scale. A simple example of interval data: The difference between 100 degrees Fahrenheit and 90 degrees Fahrenheit is the same as 60 degrees Fahrenheit and 70 degrees Fahrenheit.
