Numerical data, as the name implies, refers to numbers. View the full answer. Categorical data can take on numerical values (such as 1 indicating male and 2 indicating female), but those numbers dont have mathematical meaning. For example. Examples of nominal numbers include the number on the back of a player's football shirt, the number on a racing car, a house number or a National Insurance number. 3) Postal zip codes. Quantitative value: A nominal number is one that has no numerical value. The only difference is that arithmetic operations cannot be performed on the values taken by categorical data. It is also a discrete variable because one can simply count the number of phone calls made on a cell phone in any given day. Numerical data analysis is mostly performed in a standardized or controlled environment, which may hinder a proper investigation. Categorical data can take numerical values, but those numbers don't have any mathematical meaning. We can use ordinal numbers to define their position. Gender is an example of a nominal variable because the categories (woman, man, transgender, non-binary, etc.) This method is had to do with indexing, which is what search engines like Google, Bing, and Yahoo use. It has an added characteristic of being cyclic, since 12am follows 11pm and precedes 1am. Indicator of Behavior (IoB) analysis is extending beyond the cybersecurity domain to offer new value for finance, ecommerce, and especially IoT use cases.
