Understanding structured data
Structured data is basically tabular data; that is, data represented by rows and columns of a database. These tables contain two types of structured data, as follows:
- Numerical data: This is data that is expressed on a numerical scale. Furthermore, it is represented in two ways, as follows:
a. Continuous: Data that can take any value in an interval, such as temperature, speed, height, and so on. For example, a person's height could be any value (within the range of human heights), not just certain fixed heights.
b. Discrete: Data that can take only non-divisible integer values, such as counters. Examples include the amount of money in a bank account, the population of a country, and so on.
- Categorical data: This is data that can take only a specific set of values corresponding to possible categories. In turn, they are divided into the following categories:
a. Binary: Data that can only accept two values (0/1)
b. Ordinal: Data...
