Is cell phone number discrete or continuous?
It is also a discrete variable because one can simply count the number of phone calls made on a cell phone in any given day. The possible numbers are only integers such as 0, 1, 2, , 50, etc.
Is number of days in a month discrete or continuous?
Twelve is a counting number. Since the counting numbers ( N ) are countable, they deal with the discrete. Discrete is another way of saying not-continuous. Therefore, the calendar months would be a non-continuous random variable.
Is number of days discrete or continuous?
In fact we have discrete-time and continous-time models. It depends how did you record the time, e.g. if you count days, or record hours rounded to the nearest hour then it is rather discrete; when you record days, hours and minutes of something happening, then it is closer to continuous.
How do you determine if it is discrete or continuous?
A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A random variable is a variable whose value is a numerical outcome of a random phenomenon. A discrete random variable X has a countable number of possible values.
What type of data is a phone number?
Numerical Value Categorical data can take values like identification number, postal code, phone number, etc.
Is number of siblings discrete or continuous?
The number of siblings and student height represent numerical variables. Because the number of siblings is a count, it is discrete. Height varies continuously, so it is a continuous numerical variable.
Is the number of classes discrete or continuous?
The word discrete means countable. For example, the number of students in a class is countable, or discrete.
What is an example of continuous data?
Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data. Some continuous data will change over time; the weight of a baby in its first year or the temperature in a room throughout the day.
Are weights discrete or continuous?
So it is obvious that weight is a continuous variable as it can be quantified with decimal precision;like 10.2 kg and 3.0122 kg. If we were to round it to an integer like 10 kg and 3 kg.
What is discrete example?
The discrete values cannot be subdivided into parts. For example, the number of children in a school is discrete data. You can’t count 1.5 kids. So, discrete data can take only certain values.
What are examples of discrete and continuous variables?
Difference between Discrete and Continuous Variable
| Discrete Variable | Continuous Variable |
|---|---|
| Examples: Number of planets around the Sun Number of students in a class | Examples: Number of stars in the space Height or weight of the students in a particular class |
Is a phone number nominal or ordinal?
Nominal variables are sometimes numeric but do not possess numerical characteristics. Some of thee numeric nominal variables are; phone numbers, student numbers, etc. Therefore, a nominal variable can be classified as either numeric or not.
