Is hair continuous variable?

Since hairs are something we can count, this is a discrete random variable. Even though the number of hairs may be very large, that we wouldn’t actually want to count them, there are no “half hairs” or fractional amounts of hair, only whole number amounts of hairs.

Is hair color a discrete random variable?

These quantitative values associated to outcomes are called random variables. In this section, we explore random variables that take on numeric values that can be listed. For example, number of books is a discrete random variable. On the other hand, hair color is not a random variable because hair color is not numeric.

Is water pressure continuous or discrete?

Volume is continuous, so the amount of water would be represented by a continuous random variable. The number of minutes is countable, so it would be a discrete variable.

Which of the following random variables is an example of a discrete random variable?

If a random variable can take only a finite number of distinct values, then it must be discrete. Examples of discrete random variables include the number of children in a family, the Friday night attendance at a cinema, the number of patients in a doctor’s surgery, the number of defective light bulbs in a box of ten.

Is hair color discrete or continuous data?

discrete data
Hair colour is a type of discrete data because the values are distinct. You either have one hair colour or another! Continuous data covers a range, so each category is not separate but runs into the next.

Is hair colour discrete or continuous?

Hair colour is a type of discrete data because the values are distinct. You either have one hair colour or another! Continuous data covers a range, so each category is not separate but runs into the next.

How do you know if a variable 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.

How do you know whether a random variable is continuous or discrete?

A random variable is called discrete if its possible values form a finite or countable set. A random variable is called continuous if its possible values contain a whole interval of numbers.

What is the difference between continuous and discrete random variable?

A discrete random variable has a finite number of possible values. A continuous random variable could have any value (usually within a certain range).
