Discrete data usually involve counting a number of items, such as the number of books, computers, people, and so forth. The random variable is continuous, because it has an uncountable number of possible outcomes C. Among these two categories, quantitative data can be further classified into two types, discrete and continuous data. Example: the number of students in a class. We can compare discrete and continuous data by looking at how water comes out of a tap. A continuous time signal is an analog representation of a natural signal, with characteristically smooth transitions between peaks and valleys. And as such, money is a discrete quantity. $\endgroup$ - kjetil b halvorsen ♦ Sep 13 at 16:18 The figure below may help you understand the difference between discrete and continuous data? The best kind of aggregations come from the combination of discrete and continuous variables and do the aggregation like average sales per customers where sales is the aggregation of a continuous variable, and unique count is the aggregation of a discrete variable and finally they are combined to calculate a new average that is average sales . There is a large difference in the number of unique observations (4,999 for the continuous set and 9 for the discrete Poisson set). Continuous Variables. A discrete variable is a quantitative variable that has either a finite number of possible values or a countable number of values. Comparing discrete and continuous data. Continuous data are also referred to as variable data. The Lake of Distress is contaminated with flesh-eating bacteria!! Visually, this can be depicted as a smooth graph that gives a value for every point along an axis. Variables that take on a finite number of distinct values and those that take on an infinite number of values. Continuous Data Tutorial | Sophia Learning › discrete-vs-continuous-data-top 1. 900 seconds. And we'll give examples of that in a second. A variable whose value can be obtained by measuring is known as a continuous variable. However, if you are dealing with hundreds of pounds the steps are so small that it may be treated as a continuous variable. can only be one answer . Practice. Temperature, weight, height, and length are all common examples of continuous variables. We therefore begin by distinguishing what is continuous from what is discrete.

Sometimes variables which are strictly discrete may be treated as continuous. For example, you can have either 2 or 3 accidents but you cannot have 2.3 accidents in a month. Answer (1 of 5): Hi Khan, I usually consider money as a continuous variable, but money can also be in discrete terms: Like, oranges, per pound, in Market X a) $0.23 b) $1.05 c) $0.78 d) $0.50 e) $0.27 In Market X, oranges are only those 5 values because there are only 5 orange sellers. However, money is continuous because it can have many and any value and be of any amount, considerably. Is Money discrete or continuous? Hover on the negative side, continuous data is complex and requires a measuring instrument which adds to the cost of gathering the data. Histograms are great for presenting continuous data, while bar charts and pie charts work best for discrete data. The number of heads could be any integer value between 0 and plus infinity. Bar Graphs are good when your data is in categories (such as "Comedy", "Drama", etc). . They can assume a finite number of isolated values. However, money is continuous because it can have many and any value and be of any amount, considerably. For most analysis needs, money is continuous. With that said, I believe that currency values are discrete, because we only ever work with terminating decimal fractions of the fundamental unit of a currency, when doing intermediate calculations, and of course the final value must be an integer multiple of the fundamental unit. A continuous variable is a variable whose value is obtained by measuring, ie one which can take on an uncountable set of values. $\endgroup$ - kjetil b halvorsen ♦ Sep 13 at 16:18 The answers to the above questions are: a) Discrete, b) Discrete, c) Continuous, d) Discrete, and e) Continuous. Money does not have this property - there is always an indivisible unit of smallest currency. is a line graph discrete or continuous? The difference between discrete and continuous variables is that the former relates to a specific and often simplistic number, the value of which has been obtained purely through counting, whereas the latter is a progressive, changing number that is instead measured over time and is often complex. For example, pay, whereas it can have an infinite value. Discrete, when the variable takes on a countable number of values. Discrete date, on the other hand, can only take on integer values, and it is typically things counted in whole numbers. Discrete data can take on only integer values, whereas continuous data can take on any value. Discrete Data can only take certain values. The half of a penny cannot be valued, unless we had a half a penny coin, therefore is discrete. What we're going to see in this video is that random variables come in two varieties.
