How can you tell if a graph is discrete or continuous?

How can you tell if a graph is discrete or continuous?

When figuring out if a graph is continuous or discrete we see if all the points are connected. If the line is connected between the start and the end, we say the graph is continuous. If the points are not connected it is discrete.

Is age a discrete or continuous?

We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous. However, in everyday appliances, all values under 6 years and above 5 years are called 5 years old. So we use age usually as a discrete variable.

Is cost a discrete or continuous variable?

The variable “cost” is always rounded to 2 decimal places, and that’s why it cannot take all possible values in an interval, so this technically should be discrete. But if you measure it accurately it should be treated as continuous.

Is tire pressure discrete or continuous?

The tire pressure can take on any value between some minimum and maximum possible value, so it is continuous. If it were discrete, then only certain numbers would be possible: for example, tire pressure can be 29 psi, 29.5 psi, or 30 psi, but not any number in between.

Is color a discrete or continuous variable?

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

Is eye color a continuous variable?

And clearly hair color, skin color and eye color all fall under the definition of a continuous trait, because even though they dont seem to be affected by the environment, they are definitely polygenic traits and show a gradation, so they’re definitely continuous traits.

Is population continuous or discrete?

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 students IQ a continuous variable?

Other examples of continuous quantitative variables are temperature, age, height, weight and time. With a discrete variable it is possible to list all possible values. Other examples of discrete quantitative variables are the number of legs on an animal, number of siblings, ACT scores, IQ scores, and shoe size.

Is college major discrete or continuous?

So your college major is an categorical data.

Is family size a continuous variable?

The continuous variables can take any value between two numbers. when family size is measured as a continuous variable. Household size and number of computers are discrete variables. The range is an important descriptive statistic for a continuous variable, but it is based only on two values in the data set.

How do you know whether a random variable is continuous or discrete?

A discrete random variable has a finite number of possible values. A continuous random variable could have any value (usually within a certain range). A discrete random variable is typically an integer although it may be a rational fraction.

What are examples of continuous random variables?

In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables.

Can a random variable be both discrete and continuous?

These are random variables that are neither discrete nor continuous, but are a mixture of both. In particular, a mixed random variable has a continuous part and a discrete part. Thus, we can use our tools from previous chapters to analyze them.

What is a discrete random variable What are some examples?

A discrete random variable x has a countable number of possible values. Every probability pi is a number between 0 and 1, and the sum of all the probabilities is equal to 1. Examples of discrete random variables include: The number of eggs that a hen lays in a given day (it can’t be 2.3)

How do you convert discrete to continuous data?

You can convert measures from discrete to continuous or from continuous to discrete. Click the field and choose Discrete or Continuous. The field is green when it is continuous, and blue when it is discrete. For measures in the Data pane, right-click the field and choose Convert to Discrete or Convert to Continuous.

Is shoe size continuous or discrete?

1. Shoe size is whole number (discrete), but the underlying measure is foot length which is measurement (continuous) data. Even half sizes are still not really measurement but “whole number”, because there is nothing between size 8 and 8 1/2.

What is the difference between discrete and continuous quantitative variables?

A discrete variable is always numeric. For example, the number of customer complaints or the number of flaws or defects. 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.

What are the types of continuous variables?

There are two types of continuous variables namely interval and ratio variables.

Is personality a continuous variable?

Personality Development in Adulthood Traits are continuous variables represented by broadly encompassing lexical terms that account for individual differences (John 1990).
