In statistics numerical data is quantitative rather than qualitative.
It is numerical information about some characteristic. By contrast, qualitative data might be something like the colour of your eyes, or the name of your maths teacher.
A numerical expression is a mathematical phrase involving only numbers and one or more operational symbols. The following are some examples of numerical expressions. For example, the numerical expression 4 + 20 - 7 in the example above simplifies to the number 17.
Quantitative data is data that measures quantity, as opposed to qualitative data which describes quality. Some examples of quantitative data pertaining to weather would be: measurements of precipitation, records of number of days per month without precipitation, percentage of the chance of precipitation, records of daily high temperatures.
These are characteristics that are not represented by values. Examples of qualitative data are favourite fruit, or colour of hair etc. There may or may not be some ordering: as in never/rarely/sometimes/always or very poor/poor/indifferent/good/very good, where the frequeny or quality increases as you go from left to right but there are no numerical values attached to any of the categories.
Qualitative properties are properties that are observed and can generally not be measured with a numerical result. They are contrasted to quantitative properties which have numerical characteristics.
In statistics numerical data is quantitative rather than qualitative.
A numerical progression is a sequence of numbers displayed a predictable pattern.
The kinds of data that computers can process is endless. Computers can process numerical data, statistical information and lists of things. With the use of data management or database software many types of data can be combined together to reach different outcomes.
There are several different types of data. Some include qualitative and quantitative. Qualitative is data that is not numeric and quantitative data is numerical.
Computers store working data in RAM. Computers store long term data on hard drives.
data
You need numerical data on some characteristic of a population.
The best graph for numerical information will depend on what you want to present. The linear graph, bar and the pie graph are some of the best graphs to present numerical data.

Some advantages to direct numerical controls includes that it improves the available memory and it stores the data elsewhere but can send it directly to the machine. A disadvantage includes the possibility of hackers getting to the data since it is stored somewhere else.
