Question

Bald eagles are an endangered bird species suffering from loss of habitat and pesticide contamination of rivers. A field biologist studying the reproduction of bald eagles records the following variables. Specify whether the following variables are nominal, dichotomous, ordinal, discrete or continuous.

a. Number of eggs laid b. Incubation period (in days) c. Parental care (mostly mother, mostly father, both parents) d. Nest size (in centimeters) e. Presence of pesticides in samples of local waters (yes/no)screte or continuous.

Explanation / Answer

Answer

Here we have,

Bald eagles are an endangered bird species suffering from loss of habitat and pesticide contamination of rivers. A field biologist studying the reproduction of bald eagles records the following variables where we have to specify whether the following variables are nominal, dichotomous, ordinal, discrete or continuous.

Now as we know,

Nominal variables have two or more category without having any natural order.

Dichotomous variable is the one which takes one of the two possible values.

Ordinal variables have two or more category with having a specific natural order.

Discrete variable takes finite or countably infinite values.

Continuous variable takes uncountable values (or sometimes the values within a real valued interval).

So under these definition here we have,

a. Number of eggs laid - Discrete variable

b. Incubation period (in days) - Discrete variable

c. Parental care (mostly mother, mostly father, both parents) - Nominal variable

d. Nest size (in centimeters)- Continuous variable

e. Presence of pesticides in samples of local waters (yes/no) - Dichotomous variable.

Hence the answer..............

Thank you.............
