Identify which of the following variables are discrete and which are continuous: a. Number of warts on a toad b. Survival time after poisoning c. Temperature of porridge d. Number of bread crumbs in 10 meters of trail e. Length of wolves' canines

1. Number of warts on a toad ⇒ discrete variable

2. Survival time after poisoning ⇒ continuous variable

3. Temperature of porridge ⇒ continuous variable

4. Number of bread crumbs in 10 meters of trail ⇒ discrete variable

5. Length of wolves' canines ⇒ continuous variable

A discrete variable is the one which takes over range of real number, for a value in range that variables are permitted to take, there is minimum distance to nearest permissible value. In contrast, continuous variables are the one which can take infinitely many values.
