## What does a line graph tell you about the data?

Line graphs are useful in that they show data variables and trends very clearly and can help to make predictions about the results of data not yet recorded. They can also be used to display several dependent variables against one independent variable.

## What graph shows a change in data?

Area graphs show a change in one or more quantities over a certain period of time. They often help when displaying trends and patterns. Similar to a line graph, area graphs use dots connected by a line. However, an area graph involves coloring between the line and the horizontal axis.

**What type of data is best presented by a line graph?**

ANSWER:- Line graphs are usually used to show time series data – that is how one or more variables vary over a continuous period of time. A line graph displays that change continuously over periods of time. This graph is useful for representing the data which keeps changing over time.

### What does a line graph show?

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 does a line graph need?

The line graph consists of a horizontal x-axis and a vertical y-axis. Most line graphs only deal with positive number values, so these axes typically intersect near the bottom of the y-axis and the left end of the x-axis. The point at which the axes intersect is always (0, 0). Each axis is labeled with a data type.

**Could you use a line graph to show data about how body mass changes?**

One of the limitations of this graph is that it does not show changes over time Therefore, when showing how a body mass changes with height, it is recommended to use a line graph to track and show changes in variables.

#### What graphs to use for what data?

If you want to compare values, use a pie chart — for relative comparison — or bar charts — for precise comparison. If you want to compare volumes, use an area chart or a bubble chart. If you want to show trends and patterns in your data, use a line chart, bar chart, or scatter plot.

#### What data is used in a line graph?

**What type of data is on a line graph?**

What kind of data can be used on a line graph? A typical line graph will have continuous data along both the vertical (y-axis) and horizontal (x-axis) dimensions.

## What is the main purpose of using a line graph in presenting data?

Line graphs simply use a line to connect the data points that you plot. They are most useful for showing trends and for identifying whether two variables relate to (or “correlate with”) one another.

## How do you present data on a line graph?

On a graph, draw two lines perpendicular to each other intersecting at O. The horizontal line is x-axis and vertical line is y-axis. Mark points at equal intervals along x-axis and write the names of the data items whose values are to be marked.

**When would you use line graph to analyze data?**

A line graph is commonly used to display change over time as a series of data points connected by straight line segments on two axes. The line graph therefore helps to determine the relationship between two sets of values, with one data set always being dependent on the other set.

### When would you want to use a line graph?

Line graphs can be used when you’re plotting data that has peaks (ups) and valleys (downs), or that was collected in a short time period. An example using real education data would be if you wanted to show how the total U.S. public school student membership (enrollment) changed over a few years.

### When do you use a line graph and when do you use a bar graph?

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. . . . a Pie Chart.

**How do you make a line graph?**

Creating a Line Graph Open Microsoft Excel. Click Blank Workbook. Enter your data. Select your data. Click the Insert tab. Click the “Line Graph” icon. Select a graph style. Click a graph style.
