It can be continuous or discrete:
If you're only talking about whole numbers of years (integers) then it's discrete. If you can include parts of years (for example "I've been studying for 4 and a third years") then it's continuous.
"...4 and a third years" is not in itself discrete or continuous as a number on its own does not have this property. It's the act of breaking down the year into sub-sections (of which there are an infinite number) that makes the SCALE "years of education" continuous.
To clarify: if you're breaking a scale up into a number of sub-sections that you can count (eg. even if you specify half-years as a measure it is still discrete, as there are only 2 half-years for every year). If you're not specifying the accuracy of the measure then it's continuous as you can say 4.5, 4.6 and you can always go more accurate (4.5158956398365 for example).
It is a continuous variable.
Yes it is.
yes
What is a CONTINUOUS VARIABLE?!? If you mean a CONSTANT, then yes. Read your text. (signed) Your Teacher
It is discrete even though time itself is continuous.
continuous discrete
It is a continuous variable.
It is a continuous variable.
It is a continuous variable.
Yes. It is a continuous variable. As used in probability theory, it is an example of a continuous random variable.
No, Patient's gender is not a continuous variable. It is discrete variable.
No, it is a continuous process but not a continuous variable. The magnitude of star-shine, across all stars is a continuous variable. The magnitude of a star's shine over time is a continuous variable.
Not continuous => Discrete variable. Continuous => Continuous variable.
ocean depth is a continuous or discrete variable?
Absorbance is considered a continuous variable.
Both. It is correct to consider age as a continuous variable, but we collect data on people's ages as if they were discrete variables. Age is generally given in years, at least in humans. When we round off our numbers, we make age a discrete variable. We say a person turns 21 as if one day he's 20 years old and the next day he's 21 years old. This is the way we treat age as a discrete variable. If we considered age as a continuous variable, we would say he is 20.99 years old a day before his birthday and exactly 21 years old only on his birthday, on the exact time of his birth. After that he is 21.001 years old.
Continuous variables have an unlimited number of possibilities between two points. In the scientific realm, age is a continuous variable.
