## What type of graph is best to compare two sets of data over time?

Table of Contents

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

### What type of graph is used to present data with 2 time periods?

Multiple Line Graph This type of graph can be used to study two or more variables over the same period of time.

**Which type of graph shows a change over time?**

A line graph displays data that changes continuously over er: A line graph displays data that changes continuously over periods of time.

**Which graph works best in show change over time compared the graphs used?**

Line graphs are used to display data or information that changes continuously over time. Line graphs allow us to see overall trends such as an increase or decrease in data over time. Bar graphs are used to compare facts.

## What is a histogram vs bar graph?

Histograms visualize quantitative data or numerical data, whereas bar charts display categorical variables. In most instances, the numerical data in a histogram will be continuous (having infinite values). Attempting to display all possible values of a continuous variable along an axis would be foolish.

### What is data over time called?

Time series data, also referred to as time-stamped data, is a sequence of data points indexed in time order. Time-stamped is data collected at different points in time. These data points typically consist of successive measurements made from the same source over a time interval and are used to track change over time.

**Which type of graph would show relationships between two sets of data?**

A scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose x-y coordinates relates to its values for the two variables.

**What is the difference between a block graph and a bar chart?**

A block graph looks similar to a bar chart but it is different in a couple of ways. A block graph does not have spaces in between each category like a bar chart does. Each shaded block on a block graph is always worth one, whereas on a bar chart this is not the case.
