is iq continuous or discrete?

IQ test scores don't increment in decimals, but in whole numbers (e.g., 138, 140, 150 etc.). In other words, IQ tests only provide discrete scores [not continuous] (No body can get an IQ score of 115.568...).

continuous Discrete Attribute Has only a finite or countably infinite set of values Examples from text: zip codes, counts, or the set of words in a collection of documents, binary data.

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. ... In such a case, Y , representing the age of an individual in years, could take on a finite number of values within our range.

Discrete data can be numeric -- like numbers of apples -- but it can also be categorical -- like red or blue, or male or female, or good or bad. Continuous data are not restricted to defined separate values, but can occupy any value over a continuous range.

['Discrete variables represent counts (e.g. the number of objects in a collection).', 'Continuous variables represent measurable amounts (e.g. water volume or weight).']

Discrete variables are numeric variables that have a countable number of values between any two values. A discrete variable is always numeric. ... Continuous variables are numeric variables that have an infinite number of values between any two values. A continuous variable can be numeric or date/time.

Continuous mathematics is, roughly speaking, math based on the continuous number line, or the real numbers. ... In discrete mathematics, you're working with distinct values - given any two points in discrete math, there aren't an infinite number of points between them.

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.

IQ, short for intelligence quotient, is a measure of a person's reasoning ability. ... IQ tests begin to assess this by measuring short- and long-term memory. They also measure how well people can solve puzzles and recall information they've heard — and how quickly. Every student can learn, no matter how intelligent.

A continuous variable is a variable whose value is obtained by measuring. A random variable is a variable whose value is a numerical outcome of a random phenomenon. A discrete random variable X has a countable number of possible values. ... A continuous random variable X takes all values in a given interval of numbers.

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 .

Collectively, these skills are known as "symbolic logic." Among other things, IQ tests do not measure creativity;[i] they do not measure "practical intelligence" (otherwise known as "street smarts");[ii] and they do not measure what some psychologists call "emotional intelligence."

Why IQ test "discrete scores" are said to have "Normal shape" IQ test scores don't increment in decimals, but in whole numbers (e.g., 138, 140, 150 etc.). In other words, IQ tests only provide discrete scores [not continuous] (No body can get an IQ score of 115.568...).

An IQ score of 115 means performance one standard deviation above the median, a score of 85 performance, one standard deviation below the median, and so on. Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number by either procedure.

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.

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.

Qualitative Data are not numbers. They may include favorite foods; religions; ethnicities; etc.. Discrete Data are numbers that may take on specific, separated values. ... Continuous Data are numbers that may take on all sorts of decimal or fractional values.
