In this way, continuous data can be thought of as being uncountably infinite. No, it's not. - Try other approaches for Categorical encoding. 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). categorical, ordinal. Numerical and Categorical Types of Data in Statistics. Ordinal data are often treated as categorical, where the groups are ordered when graphs and charts are made.

Categorical data can take values like identification number, postal code, phone number, etc. For example, numerical data of a participants score in different sections of an IQ test may be required to calculate the participants IQ. It then creates an output table T_converted that contains the num-categorical-number columns of T and the categorical-number columns converted to numbers. Sorted by: 2. Categorical data can take on numerical values (such as 1 indicating male and 2 indicating female), but those numbers dont have mathematical meaning. You might pump 8.40 gallons, or 8.41, or 8.414863 gallons, or any possible number from 0 to 20. cannot be ordered from high to low. (numerical variable, discrete variable and ratio scaled) e. Where the individual uses social networks to find sought-after information. (Statisticians also call numerical data quantitative data.)

Numerical data can be further broken into two types: discrete and continuous.

\r\n \t
• Discrete data represent items that can be counted; they take on possible values that can be listed out.
