what is the difference between discrete and continuous numerical data?
16272
Discrete data is information that can only take certain values. ... Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.

Digital signal - signal is continuous in time but discrete in amplitude. Discrete in amplitude means signal cannot have multiple amplitude values . It can be a 1 or 0 . Discrete signal - signal is discrete In time but continuos in amplitude .

Digital signals must have a finite set of possible values. The number of values in the set can be anywhere between two and a-very-large-number-that's-not-infinity. ... That's the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.

Nominal, ordinal, or numerical variables? ... Nominal data is classified without a natural order or rank, whereas ordinal data has a predetermined or natural order. On the other hand, numerical or quantitative data will always be a number that can be measured.

A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. ... A discrete random variable X has a countable number of possible values. Example: Let X represent the sum of two dice.

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. Discrete data is a count that can't be made more precise.

Analog signals use a continuous variety of amplitude values whereas digital signal takes a limited set of distinct values at consistently spaced spots in the time. Analog signals are continuous in nature, whereas digital signals are discrete.

A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation. Examples of discrete quantitative variables are number of needle punctures, number of pregnancies and number of hospitalizations.

Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable. Foot length is also a continuous random variable.

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.

A discrete function is a function with distinct and separate values. ... For example, a discrete function can equal 1 or 2 but not 1.5. A continuous function, on the other hand, is a function that can take on any number within a certain interval.

The difference between a "Continuous" Transform, and a "Discrete" Transform in the wavelet context, comes from: 1) The number of samples skipped when you cross-correlate a signal with your wavelet. ... 3) The CWT uses only a wavelet, while the DWT uses both a wavelet and a scale-let.

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.

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

Analog is a continuous waveform (or record) whereas a digital recording is composed of discrete bits of data, usually represented as ones and zeroes.

Discrete data is based on counts. Only a finite number of values is possible, and the values cannot be subdivided meaningfully. ... Attribute data (aka discrete data) is data that can't be broken down into a smaller unit and add additional meaning. It is typically things counted in whole numbers.
