When it comes to data, there are various types that we encounter in our everyday lives. From numbers to words, images to videos, data is all around us.

However, not everything can be classified as data. In this article, we will explore the different types of data and identify which of the following is not a type of data.

## Types of Data

Data can be broadly categorized into four main types:

**Numerical Data:**Numerical data consists of numbers and can be further divided into two subcategories:__Discrete Data:__Discrete data includes whole numbers or integers that have a clear separation between values. For example, the number of siblings you have or the number of cars in a parking lot.__Continuous Data:__Continuous data includes decimal numbers and can take on any value within a specific range. For example, your height or weight.**Categorical Data:**Categorical data consists of non-numerical values that represent different categories or groups. This type of data is often represented by labels or names rather than numerical values. Examples include gender (male/female), colors (red/blue/green), or types of animals (dog/cat/bird).**Ordinal Data:**Ordinal data represents categories with some inherent order or ranking. The difference between each category may not be equal but there is a clear ranking present. Examples include ratings (1 star/2 stars/3 stars), survey responses (strongly agree/agree/disagree/strongly disagree), or education levels (high school diploma/bachelor’s degree/master’s degree).**Interval Data:**Interval data is similar to ordinal data but with equal intervals between each category. In this type of data, the difference between each value is meaningful and can be measured. Examples include temperature (in degrees Celsius or Fahrenheit) or years (2000/2001/2002).

## Which of the Following Is Not a Type of Data?

Now that we have explored the different types of data, let’s identify which of the following is not a type of data:

**Graphical Data:**Graphical data refers to visual representations such as charts, graphs, or diagrams that help convey information effectively. While graphical data can represent different types of data (numerical, categorical, ordinal, interval), it is not considered a separate type on its own.

In conclusion, graphical data is not a distinct type of data but rather a means of visually representing various types of data. Understanding the different types of data is essential in analyzing and interpreting information accurately.
