Question: Is Eye Color Discrete Or Continuous?

What does your eye color mean?

The color of your eyes depends on how much of the pigment melanin you have in your iris—the colored part of your eyes.

The more pigment you have, the darker your eyes will be.

Blue, grey, and green eyes are lighter because they have less melanin in the iris.

Most people in the world will end up with brown eyes..

How do you get green eyes?

Green eyes are a genetic mutation that produces low levels of melanin, but more than blue eyes. As in blue eyes, there is no green pigment. Instead, because of the lack of melanin in the iris, more light scatters out, which make the eyes appear green.

Is yes or no discrete or continuous?

Discrete data can be further sub-divided into three categories: binary, nominal and ordinal. Binary Data: A binary data only takes on two possible values. For example, lamp is on or lamp is off, answer is true or false, 0 or 1, yes or no etc. … These five responses are ordered so this would be an example of ordinal data.

What type of variable is yes or no?

A variable is said to be Binary or Dichotomous, when there are only two possible levels. These variables can usually be phrased in a “yes/no” question. Whether nor not someone is a smoker is an example of a binary variable.

Is eye Colour a variable or attribute?

Qualitative variables are those that express a qualitative attribute such as hair color, eye color, religion, favorite movie, gender, and so on. … Qualitative variables are sometimes referred to as categorical variables. Quantitative variables are those variables that are measured in terms of numbers.

What is an example of continuous variation?

Human height is an example of continuous variation. It ranges from that of the shortest person in the world to that of the tallest person. Any height is possible between these values. So it is continuous variation.

Is Money continuous or discrete?

A continuous distribution should have an infinite number of values between $0.00 and $0.01. Money does not have this property – there is always an indivisible unit of smallest currency. And as such, money is a discrete quantity.

What variable is eye Colour?

Certainly, eye color is a nominal variable, since it is multi-valued (blue, green, brown, grey, pink, black), and there is no clear scale on which to fit the different values.

Is skin tone continuous variation?

Some of these differences vary over a whole range, for example the height, skin colour and weight of people. We call this type continuous variation.

Is number of students discrete or continuous?

Discrete and Continuous Random Variables. The word discrete means countable. For example, the number of students in a class is countable, or discrete.

Is Black an eye color?

Contrary to popular belief, true black eyes do not exist. Some people with a lot of melanin in their eyes might appear to have black eyes depending on the lighting conditions. This is not truly black, however, but simply a very dark brown.

Is blood type continuous or discrete?

Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable.

Is age continuous or discrete?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.

Who has the darkest skin in the world?

Natives of Buka and Bougainville at the northern Solomon Islands in Melanesia and the Chopi people of Mozambique in the southeast coast of Africa have darker skin than other surrounding populations. (The native people of Bougainville, Papua New Guinea, have some of the darkest skin pigmentation in the world.)

Is grade a continuous variable?

Ordinal (ordered) variables, e.g., grade levels, income levels, school grades. … Continuous variables grouped into small number of categories, e.g., income grouped into subsets, blood pressure levels (normal, high-normal etc)

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

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 is the difference between a discrete and continuous variable?

Discrete and continuous variables are two types of quantitative variables: Discrete variables represent counts (e.g. the number of objects in a collection). Continuous variables represent measurable amounts (e.g. water volume or weight).

Is eye color continuous data?

Eye color is solely considered a discrete variation rather than continuous variation. It is a polygenic, hereditary trait. Since eyecolor is unchangable and, as a variable, contains a finite amount of variance, it is not able to become continuous (in the way that height, weight, and salary are continuous variables).

Is hair color discrete or continuous?

For example, number of books is a discrete random variable. On the other hand, hair color is not a random variable because hair color is not numeric. Also, any decimal between 0 and 1 is not discrete because we cannot list out all the decimals.

Which skin tone is most attractive?

A new study by Missouri School of Journalism researcher Cynthia Frisby found that people perceive a light brown skin tone to be more physically attractive than a pale or dark skin tone.
