Comparison chart: what it is, features, how to do it, examples

What is a comparison chart?

A comparison chart It is a study technique that allows us to visualize in a table the similarities and differences between two or more concepts, scientific phenomena, historical periods, authors, works of art or any other subject that we are learning.

The comparison chart is made up of rows and columns. The concepts to be compared are placed in the upper row. In the left column we will write all the variables that are relevant from the comparative point of view.

The rest of the boxes are filled with the information that corresponds according to the concept and the comparative variable.

Suppose we want to make a comparative chart of two chemical elements, potassium and chromium. We will place these two in the upper row, while the relevant comparative variables will be in the left column: symbol, atomic weight, valence, industrial utility, etc.

In principle, there are no limits to the number of concepts to be compared and the number of comparative categories that we wish to add.

Features of a Comparison Chart

It is an effective tool to summarize the information contained in long texts. The information placed in each box is brief and precise. It is useful not only for learning, but also for presenting information to an audience, whether at school exhibitions or at a corporate level. Both information in numbers and qualitative information can be represented. It is a very effective tool for a quick review of the material already studied.

How to make a comparison chart

To create a comparative table you must follow these four steps:

1. Define which are the elements you want to compare

Suppose that the subject of our comparison chart is the cell, and that the elements to be compared are the animal cell and the plant cell.

2. Gather information

The next step is to obtain the information with which we will fill our comparative table.

For that, it is essential to investigate: in biology textbooks, on the internet, in scientific articles, in popular science books.

Everything will depend on the academic level of the comparative chart and how exhaustive you want the information contained in it to be.

3. Read, reread and underline

This is the key stage in the preparation of the comparative table. Ideally, read the selected material at least twice. The first time as an exploratory reading, and a second time to underline the key information of the text or texts that have served as a source.

Remember that a comparison chart is fundamentally the product of a summary process. Therefore, it is necessary that you think carefully about what is the really relevant content to be placed in the box and what things can be left out. Read the background material more than twice if necessary.

4. Establish the comparative variables

Select the most important ones, although you can place as many as you can think of or the information contained in the texts you have used as a source allows.

For example, in the case of our comparative chart between plant and animal cells, some comparative variants could be: cell wall, chlorophyll, mobility, feeding, among others.

Our comparative chart would look like this:


It does not have a cell wall. It has a cell wall.

It has chloroplasts with chlorophyll. It lacks chlorophyll.

It is immobile. Some types are mobile.

autotrophic. Through photosynthesis they produce their own food. heterotroph. They ingest food particles that are processed inside.

Other Examples of Comparison Charts

Comparative table between myth and legend


It is a story of a fictional nature that provides an explanation of the origin of the world and other existential questions. It is a fictional story that ingeniously explains the origin of some geographical object or phenomenon (a musical instrument, a mountain) of cultural importance for the community where the legend is born. It has a certain real basis.

The myths are carried out mainly by gods, although heroes or ordinary human beings can also appear, arousing the desire, anger or sympathy of the deities. The protagonists of the legend are usually animals or ordinary people. The intervention of some divine power is not ruled out, but this is only circumstantial.

The purpose of myths is to offer an answer in the form of a story to the great existential questions: where we come from, how we were created, what awaits us after death, etc. Legends are intended to explain how certain things were created or came to exist, such as the lyre among the Greeks. Another objective of the legends is to teach moral values ​​through stories.

They can be considered fictitious, although it is possible that for the members of the social group where the myth was born, it is considered indisputable truth. They can be considered fictitious. This is also how they are considered by the majority of the members of the social group where they were born.

Comparison chart between Moral and ethic

The word «ethics» has its origin in the Greek word ethos, whose meaning is habit or way of doing things.

The word «moral» originates from the Latin term mores, which means custom.

It is a branch of philosophy that asks about how an individual should act in a given situation or what are the values ​​by which they should be governed. It uses reasoning and observation.

Morality is the set of rules of conduct that a certain society, in a specific historical period, considers correct and valuable.

1) It is based on rational thought and observation.

2) It aspires to draw conclusions of universal validity, that is, that can be considered correct in any historical place and time.

3) Ethical thought is born in the personal concerns of the individual.

1) It is based on opinions shared by the majority of the members of a society.

2) Its rules are not universal. They belong to a specific society and time, and can change significantly.

3) Morality is an inheritance: all individuals are born in societies whose moral rules are already established and which they must learn and respect.
