collection of all possible information worths for a given topic under considerationexample: if we are researching the weight of adult woguys, the populace is the collection of weights of all the women in the human being.

You are watching: A set of all possible data values for a subject under consideration is called ___.


In statistics, a categorical variable is a variable that have the right to take on one of a restricted, and also normally resolved, number of possible worths, thus assigning each individual to a details team or "category."
Quantitative Variable. Variables that have are measured on a numeric or quantitative scale. Ordinal, interval and also ratio scales are quantitative. A country"s population, a person"s shoe size, or a car"s rate are all quantitative variables.
A type of variable, also dubbed a categorical or nominal variable, which has actually a finite number of feasible values that perform not have actually an natural order. For instance, hair shade would certainly be a discrete variable, because it can just have actually a limited variety of values, such as red, brvery own, and black, that does not occur in any kind of certain order
If a variable can take on any type of value between its minimum worth and its maximum value, it is referred to as a continuous variable; otherwise, it is referred to as a discrete variable. example: Suppose the fire department mandates that all fire fighters should weigh between 150 and 250 pounds. The weight of a fire fighter would be an example of a consistent variable; given that a fire fighter"s weight could take on any kind of value between 150 and also 250 pounds.
A value that "lies outside" (is a lot smaller or bigger than) many of the various other worths in a collection of information.exactly how to find:For the data 2, 5, 6, 9, 12, we have the complying with five-number summary:minimum = 2first quartile = 3.5median = 6third quartile = 10.5maximum = 12IQR = 10.5 - 3.5 = 7, so 1.5·IQR = 10.5.To identify if there are outliers we must take into consideration the numbers that are 1.5·IQR or 10.5 beyond the quartiles.initially quartile - 1.5·IQR = 3.5 - 10.5 = -73rd quartile + 1.5·IQR = 10.5 + 10.5 = 21
The standard deviation is a numerical worth used to indicate how extensively individuals in a team varyexactly how to find: square root of the variance
In probability concept and also statistics, variance procedures how far a set of numbers is spcheck out out. A variance of zero suggests that all the values are identical.how to find: To calculate the variance follow these steps: Work out the Typical (the straightforward average of the numbers) Then for each number: subtract the Typical and square the outcome (the squared difference). Then work out the average of those squared distinctions.

A formula for the variety of feasible combicountries of r objects from a set of n objects. This is written in any of the ways displayed listed below. All forms are read aloud "n select r.
A permutation is an arrangement of all or part of a collection of objects, with regard to the order of the arrangement. For instance, expect we have actually a set of three letters: A, B, and C. We can ask exactly how many kind of methods we deserve to arvariety 2 letters from that set.nPr
