Question

Scientists did a 10-year study to investigate the effect of tagging penguins with either a metal strip or an electronic tag. In the student, a sample of 100 penguins were randomly assigned to one of two groups, then followed for 10 years. The study learned that, overall, penguins tagged using a metal strip had fewer chicks, had a lower survival rate (percent to survive over the decade), and on average took significantly longer on foraging trips than penguins who were tagged with an electronic tag.

• Which variable is the explanatory variable? Which ones can be considered response variables?

Answer 1

ANSWER::

1) The explanatory variable : Explainatory variable is also known as the independent variable.

Explanatory variables are

* Electronic tag and

* Metal strip tag for penguins.

These variables are categorical variables as they cannot be measured in numbers.

2) Response variables is also known as a dependent variable :

Response variables are

* Survival rates

* Number of chicks and

* Foraging trip duration by penguins.

These variables are quantitative variables as they can be measured in numbers.
