## What are multivariate maps used for?

## What is a univariate map?

Our focus has been primarily on univariate maps—**maps that show only one thematic data attribute**. This is a good start, but cartographers often wish to map more than one variable in a thematic map. This is called multivariate mapping.

## How do you show multiple variables on a map?

In the Change data menu, click **Change data**. Click the category you're interested in. Scroll and select the variable you want to visualize on the map. After the first map is created, select the other variable or variables you want to add by checking the boxes next to all of the variables you want to add to the map.

## What is a Cartogram map used for?

Cartograms are used for **thematic mapping**. They are a particular class of map type where some aspect of the geometry of the map is modified to accommodate the problem caused by perceptually different geographies.Sep 4, 2017

## What is the difference between a bivariate and a multivariate map?

Bivariate analysis looks at **two paired data sets**, studying whether a relationship exists between them. Multivariate analysis uses two or more variables and analyzes which, if any, are correlated with a specific outcome.Jun 4, 2018

### What is a bivariate Choropleth map?

Bivariate choropleth maps **combine two datasets (usually numerical data) into a single map allowing us to show relatively how much of X (variable 1) and Y (variable 2) exist in each enumeration unit**. ... Like all bivariate maps, these maps encode two numbers/facts per location and are, therefore, graphically efficient.

### When should you not use a cartogram?

When Not to Use a Cartogram

Maps depend on variation in scale to represent a large area and **a cartogram is not a true representation of the real-world area** and may give incomplete information. One of the disadvantages of the cartogram is that it inevitably changes the visual representation of geography.
