With Formplus, you can analyze respondents data, learn from their behaviour and improve your form conversion rate. It cannot be taken as a quantitative variable as it does not make sense to do any numerical calculation on a phone no like an average phone number is not a meaningful thing , it is not a measure of something.

The list of possible values may be fixed (also called finite); or it may go from 0, 1, 2, on to infinity (making it countably infinite).For example, the number of heads in 100 coin flips takes on values from 0 through 100 (finite case), but the number of flips needed to get 100 heads takes on values from 100 (the fastest scenario) on up to infinity (if you never get to that 100th heads). In some texts, ordinal data is defined as an intersection between numerical data and categorical data and is therefore classified as both. We can use ordinal numbers to define their position. Sorted by: 2. (Statisticians also call numerical data quantitative data.)
\r\nNumerical data can be further broken into two types: discrete and continuous.

- Discrete data represent items that can be counted; they take on possible values that can be listed out. No, it's not. Categorical data is a type of data that can be stored into groups or categories with the aid of names or labels. Categorical variables are those that provide groupings that may have no logical order, or a logical order with inconsistent differences between groups (e.g., the difference between 1st place and 2 second place in a race is not equivalent to the difference between 3rd place and 4th place). A Discrete Variable has a certain number of particular values and nothing else. Both numerical and categorical data can take numerical values. They are used only to identify something. With years, saying an event took place before or after a given year has meaning on its own. Categorical data is data that is collected in groups or topics; the number of events in each group is counted numerically. Interval data: This is when numbers have units that are of equal magnitude as well as rank order on a scale without an absolute zero. However, the quantitative labels lack a numerical value or relationship (e.g., identification number). Each observation can be placed in only one category, and the categories are . In addition, determine the measurement scale. Categorical data is enormously useful but often discarded because, unlike numerical data, there were few tools available to work with it until graph DBs and streaming graph came along. Census data, such as citizenship, gender, and occupation; ID numbers, phone numbers, and email addresses. Edit. However, they can not give results that are as accurate as the original.
