Answer:
(a) Continuous,
(b) Discrete,
(c) Continuous.
Step-by-step explanation:
We are asked to classify each variable as discrete or continuous.
(a) The time it takes to drive to University.
We know that continuous data can take any values within a range, while discrete data can take only certain values.
Height, weight, time are typical examples of continuous data.
Since it can take some minutes or hours to reach university, therefore, the given variable is continuous.
(b) The number of credit cards a person has.
The number of credit cards a person can take lie in the group of positive integers. Since a person can take finite number of credit cards, therefore, the given variable is discrete.
(c) The weight of pumpkins.
We know that the weight of all pumpkins cannot be similar. The weight of pumpkins can be between some kg to some pounds, therefore, the given variable is continuous.
By analyzing each variable, we will see:
- a) Continuous.
- b) Discrete.
- c) Continuous.
How to identify the variables?
There are two types, discrete and continuous.
Continuous variables are the ones that can take any real value in a given interval.
Discrete variables are the ones that can only take some selected values on a given interval.
Now let's analyze each option:
a) "The time it takes to drive to University."
Time can take any real value, so this is a continuous variable
b) "The number of credit cards a person has."
This number can only be a whole number (a person can't have 0.423 credit cards). Then only a few values are accepted, meaning that this is a discrete variable.
c) "The weight of pumpkins"
Mass, like time, can take almost any real value (if you go to quantum mechanics this is not the case) but macroscopically, we say that mass is a continuous variable, so also is weight.
