Why is time a continuous variable?
a variable that may in theory have an infinite number of possible values. For example, time is a continuous variable because accurate instruments will enable it to be measured to any subdivision of a unit (e.g., 1.76 seconds).
How do you know if it is continuous or discrete?
A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring.
What is discrete data give examples?
Discrete data is information that we collect that can be counted and that only has a certain number of values. Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit.
Is absences discrete or continuous?
For the percentage of people absent in the class, it is a ratio of two discrete numbers and hence should be treated as discrete.
Is weight continuous or discrete?
Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.
Is time measured discrete or continuous?
Time is a continuous variable, it can take any positive value in an interval. Even when we measure it in minutes, it can be measured with infinite precision, for example: 0.125 minutes or 0.13333 minutes.
Is time continuous data?
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.
Is student ID number discrete or continuous?
The word discrete means countable. For example, the number of students in a class is countable, or discrete.
Is height discrete or continuous?
Height, weight, temperature and length are all examples of continuous data.
Is the speed of a car continuous or discrete?
The speed of a car is an example of continuous variable.
Is number of days a continuous variable?
If a variable is measured by counting, such as the case if a researcher is counting the number of days a hospital patient has been hospitalized, the variable is on a ratio scale and is treated as a continuous variable.
What is an example of discrete time?
Discrete time is often employed when empirical measurements are involved, because normally it is only possible to measure variables sequentially. For example, while economic activity actually occurs continuously, there being no moment when the economy is totally in a pause, it is only possible to measure economic activity discretely.
Is time discrete or continuous in nature?
Time itself is continuous, i.e. intervals shorter than the Planck Time exist. But these shorter intervals are trivial, so time may as well be discrete. Additionally, if time is discrete then distance as well must be discrete. It’s weird to think of the universe as pixelated… – chharvey Sep 5 ’12 at 23:25
What is an example of continuous time?
Continuous time. Continuous time makes use of differential equations. For example, the adjustment of a price P in response to non-zero excess demand for a product can be modeled in continuous time as where the left side is the first derivative of the price with respect to time (that is, the rate of change of the price),…
How do you represent continuous and discrete data?
Continuous information is information that falls into a continuous series. Discrete data is countable. There are distinct or different values in discrete data. Every value within a range is included in continuous data. The bar graph is used to graphically represent discrete data. A histogram is used to graphically represent continuous data.
