A simple line graph is **a kind of graph that is plotted with only a single line**. Like in the diagram above, shows the relationship between two variables. In most cases, one of these variables is independent, while the other is a dependent variable.

## What does a line plot tell you?

What is a Line Plot? A Line plot can be defined as a graph that displays data as points or check marks above a number line, **showing the frequency of each value**. Here, for instance, the line plot shows the number of ribbons of each length.

## How do you analyze a line graph?

Interpreting Line Charts

The changing slope of the line segments emphasizes changes, trends, and patterns. For a single series of data, **assess the changes in the line to identify trends and patterns**. When you have multiple metrics, compare their lines to determine whether they have the same trend and patterns.

## How do you read a line graph?

How to read it. First, **look at the axes to understand what the chart is showing.** Then examine the chart to see the values of the points in the lines. Follow the lines and see if there are any trends, sudden rises or falls, repeating patterns, or places where lines cross each other.

## What data are presented in the line graph?

Line charts compare two variables: one is plotted along the x-axis (horizontal) and the other along the y-axis (vertical). **The y-axis in a line chart usually indicates quantity (e.g. dollars, litres) or percentage, while the horizontal x-axis often measures units of time**.

Linear graph is represented in the form of **a straight line**. To show a relationship between two or more quantities we use a graphical form of representation. If the graph of any relation gives a single straight line then it is known as a linear graph.

## How does a graph work?

**Graphs have two axes, the lines that run across the bottom and up the side.** **The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis**. The x-axis may contain categories or numbers. You read it from the bottom left of the graph.

## Why are line plots important?

Line plots are used to display numerical, discrete data only, not the continuous data. Line plots organize the data by indicating the occurrences of each value on a number line. These graphs are easily constructed with small data sets, and allow for interpretation based on the frequency patterns that are revealed.

**Bar graphs are best for comparing categories.** **Line graphs are used to show trends over time**.

## How do you describe a line graph trend?

Line graphs typically show trends. A trend is a movement of data in a general direction over time. On a line graph, **trends are represented by the direction of the lines**. Trends can be upward or downward or they can remain at the same level.

## 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 write a line graph description?

Begin the first body paragraph writing with individual lines. However don’t forget to mention the starting point of a line, the trends such as constantly increasing, gradually decreasing, stable, etc. and peak points. Moreover, write the second body paragraph comparing the multiple lines together.

## Which two features are parts of a line graph?

A line graph, also known as a line chart or a line plot, is commonly drawn to show information that changes over time. You can plot it by using several points linked by straight lines. It comprises two axes called the “x-axis” and the “y-axis”. The horizontal axis is called the x-axis.

## Which option best describes the function of a line graph?

Which option best describes the function of a line graph? **To display related data points in a continuous series**.

## Which part of the line graph tells us what is being represented?

A line graph has two axes. The x-axis of a line graph shows the occurrences and the categories being compared over time and the y-axis represents the scale, which is a set of numbers that represents the data and is organized into equal intervals.

## How do you prepare a line graph?

- Step 1: Identify the variables. …
- Step 2: Determine the variable range. …
- Step 3: Determine the scale of the graph. …
