Knowing what kind of data you are dealing with is an essential phase to better extract insights from the data; since for each data type, you need to use the right mathematical techniques and visualization types.

### Categorical

Data is labeled categorical if their values describe a quality, grade, level, or any other characteristics. Categorical data can be Nominal or Ordinal.

#### Ordinal

Ordered variables where the number of units in each variable is not the same.

#### Examples of Ordinal Data

Data is ordinal if it represents an ordered quality variable, and the number of units in each variable is not the same.

Levels

On
a
happiness scale, joy (high) has more units
of
happiness
than sad (low.)

Times of
day

Morning is 6 hours,
whereas
evening
lasts for about 3 hours.

Stages
of education

Elementary
school
has 8
grades and lasts for 8 years, whereas
college
consists
of 4 grades and lasts 4 years.

#### Nominal

Categorical data where the order doesn't matter.

#### Examples of Nominal Data

Nominal data is a type of categorical data where the order doesn't matter.

Gender

Countries' names

Colors

Tip: To identify nominal data, ask yourself the following question: Will the meaning change if I change the variables' order? If not, you have nominal data.

### Continuous

Data is labeled continuous if the values are measured. Continuous data could be either interval or ratio.

#### Interval

Data where proportion doesn't make sense, and the zero has no meaning.

#### Examples of Interval Data

Interval data represents values where proportion doesn't make sense, and the zero has no meaning.

Intelligence quotient

Temperature

Time of the
day

1 pm, 2 pm, 4 am, etc

Tip: Interval data is often used in the social sciences.

#### Ratio

Data where the zero functions as a point of reference, and proportions make sense.

#### Examples of Ratio Data

For ratio data, the zero has a meaning as a point of reference, and proportions make sense.

Distance

5km,
1,84m, etc.

Weight

81.5kg

Days

2
or 3
days

Times

1
hour,
34min

Tip: Notice that ratio data does not have negative values, as there is no negative height or weight. Ratio data is popular in physical sciences.

## 2. Define your Objective

There are many objectives to visualize a data set. Here are the main commonly used objectives:

### Comparison

Comparison estimates the similarities or not between two or more elements. Line, Bar, Bubble charts, and Treemaps are often used to compare categorical data.

### Composition

Composition shows the continuent parts of an element. Donut, Pie, Stacked Bar, and Stacked Column charts are often used to visualize composition.

### Relationship

Relationship demonstrates how one variable affects other variables. Scatter and Bubble charts are often used to visualize relationship.

### Hierarchy

The hierarchy is a system where elements are arranged or ranked one above another. Treemap, Sunburst, and Circle chart are used to visualize hierarchy.

### Distribution

Distribution depicts the frequency of a variable through time or space. Scatter, Histograms, and Pyramid charts are used to visualize distribution.

### Flow

The flow is the action of moving along in a steady and continuous stream. Sankey diagram and Gantt are the main charts used to visualize the flow.
