Question

A scientist hypothesizes that the temperature at which an alligators egg is incubated will determine whether the alligator will be male or female. What is the variable?

Answer 1

Variable is the object where the observation will either influence or receive the effect from the other object or variable. Hence, variables divided into two distinct parts in a study or traditionally an experimental study which is the independent variable and the dependent variable. The independent variable is the variable that can stand for itself until it affects the dependent variable, which is the variable that was influenced by the independent variable.

IV: Gender of the alligator
DV: Temperature at which the alligator mother will need to supply.

Answer 2

Answer:

Variables refer to the components of an experiment that change during the course of the experiment.

There are usually three types of variables in any experiment:

Independent variables: these are variables which are change or control by the scientists. Alternatively, they are defined as the variables the effects of which are bring studied.

Dependent variables: these are variables which depend upon independent variables.

Controlled variables: these are the set of variables the quantity of which are kept constant throughout the experiment.

• So, temperature at which eggs are being incubated form the independent variables.

• The gender of the offspring form dependent variables as it depends upon the temperature of incubation.

• Controlled variables may include surrounding factors such as food, water, environmental conditions et cetera.
