Which variables are always discrete?

Discrete variables are numeric variables that have a countable number of values between any two values. A discrete variable is always numeric. For example, the number of customer complaints or the number of flaws or defects.

Which variables are discrete?

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 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.

What are 3 examples of discrete data?

Which data are discrete?

Discrete data is information that can only take certain values. These values don't have to be whole numbers (a child might have a shoe size of 3.5 or a company may make a profit of £3456.25 for example) but they are fixed values – a child cannot have a shoe size of 3.72!

What are the two types of discrete variables?

Discrete variables may be further subdivided into: Dichotomous variables. Categorical variables (or nominal variables)

Discrete and continuous random variables | Probability and Statistics | Khan Academy

Are ordinal variables discrete?

Variables may be classified into two main categories: categorical and numeric. Each category is then classified in two subcategories: nominal or ordinal for categorical variables, discrete or continuous for numeric variables.

Is interval data discrete?

Interval data is one of the two types of discrete data. An example of interval data is the data collected on a thermometer—its gradation or markings are equidistant. Unlike ordinal data, interval data always take numerical values where the distance between two points on the scale is standardised and equal.

Which is not discrete data?

Discrete data take particular values, while continuous data are not restricted to separate values. Discrete data are distinct and there is no grey area in between, while continuous data occupy any value over a continuous data value. Cite.

Is time a discrete or continuous variable?

Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person's age in years.

Is weight continuous or discrete?

So it is obvious that weight is a continuous variable as it can be quantified with decimal precision;like 10.2 kg and 3.0122 kg.

Is population discrete or continuous?

Population counts are typically referred to as discrete or quantitative data. Why is population density a continuous data type when it is typically measured for aggregate areas such as census tracts or districts/neighbourhoods (ie, it can't be measured at any point on a surface like gradient or temperature).

Is height a discrete variable?

As a result, we can say, that height is a continuous variable. Because we cannot define a specific set of values, that incorporate every possible height of any human being.

Is color a discrete variable?

Examples. The following are examples of discrete variables: Gender. Eye color (brown, blue, green, hazel)

Is length discrete or continuous?

Length of a film is a continuous variable. Number of pages in a book is a discrete variable. Shoe size is a Discrete variable. E.g. 5, 5½, 6, 6½ etc.

Is age a discrete variable?

Is Age Discrete or Continuous? Technically speaking, age is a continuous variable because it can take on any value with any number of decimal places.

How do you know if data is discrete or continuous?

Discrete data is countable while continuous data is measurable. Discrete data contains distinct or separate values. On the other hand, continuous data includes any value within range. Discrete data is graphically represented by bar graph whereas a histogram is used to represent continuous data graphically.

Is price discrete or continuous?

Price is a continuous variable because it can be scaled up and down. It lowest unit of measurement is, for example, a cent. Even other continuous variables have lowest units of measurement, not just price.

Is speed discrete or continuous?

Yes, speed is a common continuous variable, and the value is chosen by a random process. We know it is continuous because there is always another possible value between any two speed values.

Is temperature discrete or continuous?

Temperature is continuous variable as it does have fractional value too. For example: Today's temperature is 30. 5 degree Celsius, here 30. 5 is not a discrete variable and hence is a continuous variable.

Are nominal variables discrete?

Categorical variables are also known as discrete or qualitative variables. Categorical variables can be further categorized as either nominal, ordinal or dichotomous. Nominal variables are variables that have two or more categories, but which do not have an intrinsic order.

What is discrete data example?

Examples of discrete data

The number of customers who bought different items. The number of computers in each department. The number of items you buy at the grocery store each week.

Is ordinal scale continuous or discrete?

Categorical and dichotomous usually mean that a scale is nominal. "Continuous" variables are usually those that are ordinal or better.
