Previous studies on the genetics of human eye color used broadly-categorized trait information such as 'blue', 'green', and 'brown'. However, variation in eye color exists in a continuous grading from the lightest blue to the darkest brown.
Discrete data is organised in separate categories and is often presented in a bar chart. Examples of types of discrete data include: eye colour, hair colour, number of people in a shop, favourite chocolate bar. These values are distinct. Hair colour is a type of discrete data because the values are distinct.
Eye color is not a quantitative variable, it is a categorical random variable.
A continuous variable is one which can take on a value between any other two values, such as: indoor temperature, time spent waiting, water consumed, color wavelength, and direction of travel. Often a variable will be continuous at one scale, but discrete on another.
The 'eye colour of a pupil' is an attribute of an individual and is an example of qualitative data, the 'numbers of pupils with each eye colour' is a variable consisting of quantitative data. So, there are two basic ways of collecting quantitative data – by measuring and by counting.
Terms in this set (11) Is the eye color of people on commercial aircraft flights a discrete random variable, a continuous random variable, or not a random variable? It is not a random variable.
The color spectrum is continuous, but, paradoxically, the number of colors indentifiable by the human eye is finite. It is a big number, though, such that considering it infinite is a good approximation. What happens is that we have a discrete number and types of light sensing cells.
Eye colour is qualitative variable, also called a categorical variable. The categories are not ordered. Such a variable is also called nominal.
The 'eye colour of a pupil' is an attribute of an individual and is an example of qualitative data, the 'numbers of pupils with each eye colour' is a variable consisting of quantitative data.
Discrete data is the type of data that has clear spaces between values. Continuous data is data that falls in a constant sequence. Discrete data is countable while continuous — measurable. To accurately represent discrete data, the bar graph is used.
Categorical variables can be dichotomous (also called binary), nominal or ordinal. Nominal variables (from Latin for name) are things like eye colour or hair colour.

A continuous color scale allows for seeing greater variance in your data while a discrete color scale may help you make out patterns that are more difficult to see without limiting the number of colors in your palette. Try switching between the two color scale types below and seeing what you notice.
Examples. The following are examples of discrete variables: Gender. Eye color (brown, blue, green, hazel)
The 'eye colour of a pupil' is an attribute of an individual and is an example of qualitative data, the 'numbers of pupils with each eye colour' is a variable consisting of quantitative data.
Discrete Color Concepts color sequences are lists of colors to be mapped onto discrete data values. No interpolation occurs when using color sequences, unlike with continuous color scales, and each color is used as-is.

Though glassing was previously thought to be permanent, it is possible through terraforming to reclaim the environment of a glassed planet, though a planet such as Reach was shown to have taken at least 37 years to recover. In the Halo: Reach multiplayer map Highlands the planet is being glassed.
