is time a continuous variable?

Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person's age in years.

Psykolord1989 . Answer: Continuous if looking for exact age, discrete if going by number of years. If a data set is continuous, then the associated random variable could take on any value within the range.

is that duration is an amount of time or a particular time interval while timing is (obsolete) an occurrence or event.

Difference between Variable and Constant A constant does not change its value and it remains the same forever. A variable, on the other hand, changes its value from time to time depending on the equation. Constants are usually represented by numbers.

Variable Type Vs. Consider the variable age. Age is frequently collected as ratio data, but can also be collected as ordinal data. ... Variables that are naturally ordinal can't be captured as interval or ratio data, but can be captured as nominal.

Discrete variables are measured across a set of fixed values, such as age in years (not microseconds). These are commonly used on arbitrary scales, such as scoring your level of happiness, although such scales can also be continuous.

The absolute value function is continuous at 0. Computations of the two one-sided limits of the absolute value function at 0 are not difficult to complete. Since |x| = x for all x > 0, we find the following right hand limit. ... In fact, the absolute value function is continuous (on its entire domain R).

Money changes in steps of 1p and so is a discrete variable. However, if you are dealing with hundreds of pounds the steps are so small that it may be treated as a continuous variable.

When a function is differentiable it is also continuous. But a function can be continuous but not differentiable. For example the absolute value function is actually continuous (though not differentiable) at x=0.

A continuous variable can take on any score or value within a measurement scale. In addition, the difference between each of the values has a real meaning. Familiar types of continuous variables are income, temperature, height, weight, and distance. There are two main types of continuous variables: interval and ratio.

Observations can take any value between a certain set of real numbers. The value given to an observation for a continuous variable can include values as small as the instrument of measurement allows. Examples of continuous variables include height, time, age, and temperature.

A discrete variable has a complete range of values. ... A continuous variable is uncountable while a discrete variable has countable values. The data set for a discrete variable is finite meaning it has an end value while a continuous variable can take up an infinite value which implies that it can have endless values.

What is the difference between a categorical and continuous variable? a). Categorical are assigned to discrete categories; continuous can take any value in a range.

What is the Difference between Constant and Variables? A constant does not change its value over time. A variable, on the other hand, changes its value dependent on the equation. Constants are usually written in numbers.

Discrete-time signals are defined at the discrete moment of time and the mathematical function takes the discrete set of values. Continuous-time signals are characterised by independent variables that are continuous and define a continuous set of values.
