If you're a strict literalist, the answer is "yes"—when we measure a property that's continuous, like height or distance, we are de facto making a discrete assessment. In the real world, money could also be considered both discrete and continuous- you cannot have $ π in your bank account so therefore in that sense, money is discrete. Discrete Or Continuous: The discrete variable is the variable that can take only a finite number of values in an interval. Another clue is that continuous variables are often stated as fractions or decimals, as in 2.5 gallons of gas. Clear, concise examples. For example, take age. Really helpful.. The number of parts damaged during transportation. When we collect a lot of those discrete measurements, it's the amount of detail they contain that will dictate whether we can treat the collection as discrete or continuous.

You can treat any numerical variable as continuous if it has enough possible values. Example: The amount of money spent by a family in one month. Discrete if measured in a number of years, minutes, seconds. Let’s see the definition: Continuous data is information that could be meaningfully divided into finer levels. The definition of a continuous quantity. That is why, when we do something with discrete and continuous data, actually we do something with numerical data. CONTINUOUS VERSUS DISCRETE. For example, 1 and ½ pennies can’t be measured; the monetary value of one and ½ pennies can only be valued as a rounded amount of 2 pennies. Eduardo_Bernal03. Online Tables (z-table, chi-square, t-dist etc. If both Y and Xs are continuous then Regression can be used. There could be 1 pint, 2 pints, or any other amount up to the capacity of the jug. Thank you for clarification!! For example, money is measured in increments, for example of 1 cent, so that should make it discrete. 1.Discrete Data 2.Continuous Data Below table illustrates how data type determines which statistical test can be applied in a given scenario. Continuous random variables are usually measurements. Time to complete a task is continuous since it could take 178.8977687 seconds. Tabulation of discrete data, done against a single value, is called as an ungrouped … The half of a penny cannot be valued, unless we had a half a penny coin, therefore is discrete. the numbers go on and on until infinity), you have what’s called a continuous variable. You can’t count 1.5 kids. A person’s weight, gallons of water, the length of a football field, the speed of a car, the temperature of the ocean, price of gas, all must be measured, so they are continuous variables. As they are the two types of quantitative data (numerical data), they have many different applications in statistics, data analysis methods, and data management. If your data values are all integers, this means that the "total work" and "sleep" are both being measured in whole minutes (i.e., part minutes are not being recorded). Discrete data may be also ordinal or nominal data (see our post nominal vs ordinal data). The amount of time it takes to sell shoes. Because it would literally take forever.

However it would be continuous if measured to an exact amount of time passed since the start of something. Thanks to the developers. The number of test questions you answered correctly. A discrete variable is always numeric. Discrete Data. Discrete time views values of variables as occurring at distinct, separate "points in time", or equivalently as being unchanged throughout each non-zero region of time ("time period")—that is, time is viewed as a discrete variable.Thus a non-time variable jumps from one value to another as time moves from one time period to the next. T HE SUBJECT MATTER OF DIFFERENTIAL CALCULUS is rate of change; specifically, the rate of change at a given value of a continuous function, such as the speed of motion. For example, if Y (dependent variable) is continuous and Xs (independent variables) are discrete then we can use ANOVA to test means. You can count them.
