is average speed discrete or continuous?

Yes, speed is a common continuous variable, and the value is chosen by a random process. We know it is continuous because there is always another possible value between any two speed values.

It is different from average speed because average speed is measured by the total time of a journey divided by the total distance. In contrast, instantaneous speed measures the smallest interval possible divided by the time it took to move that distance.

A discrete variable is one that cannot take on all values within the limits of the variable. ... The variable cannot have the value 1.7. A variable such as a person's height can take on any value. Variables that can take on any value and therefore are not discrete are called continuous.

Average velocity is defined as the ratio: displacement divided by time elapsed. It has both magnitude and direction. Average speed is defined as the ratio: distance traveled divided by time elapsed.

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.

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.

Speed is a scalar, and average velocity is a vector. Average velocity indicates direction and can be represented as a negative number when the displacement is in the negative direction. Average speed does not indicate direction and can only be positive or zero.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time. Movement can be shown in distance-time and velocity-time graphs.

The difference between discrete and continuous data can be drawn clearly on the following grounds: ... Discrete data is countable while continuous data is measurable. Discrete data contains distinct or separate values. On the other hand, continuous data includes any value within range.

Quantitative Flavors: Continuous Data and Discrete Data There are two types of quantitative data, which is also referred to as numeric data: continuous and discrete. As a general rule, counts are discrete and measurements are continuous.

Instantaneous velocity is a vector and can be negative. Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time.

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.

There are two types of random variables, discrete and continuous.

Discrete data is normally recorded on a block graph or bar chart. There should be gaps between the bars to show that data is discrete. Continuous data results from measurements such as lengths of caterpillars or weights of crisp packets, and may be organised in touching but non-overlapping groups.

The most common discrete graphs are those that represent sequences and series. These graphs do not possess a smooth continuous line but rather only plot points above consecutive integer values. Values that are not whole numbers are not represented on these graphs.

The instantaneous velocity is the specific rate of change of position (or displacement) with respect to time at a single point (x,t) , while average velocity is the average rate of change of position (or displacement) with respect to time over an interval.

Continuous and discrete are mathematical terms. Continuous means "forming an unbroken whole, without interruption"; discrete means "individually separate and distinct." ... When you drag a field from the Data pane to Columns or Rows, the values are continuous by default and Tableau creates an axis.
