## Which graph is used to show change in a given variable when a second variable is changed bar graph line graph histogram?

**A line graph** is often the most effective format for illustrating a relationship between two variables that are both changing.

## Which graph is used to show changes between two quantities?

**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 do you call a graph which shows how much one variable is affected by another variable?

**Scatterplot**. ▪ The most useful graph for displaying the relationship between two quantitative variables is a scatterplot.

## Which type of graph should he use to display his data?

**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 double bar graph?

A double bar graph is **a graphical representation of information setting two bars besides each other of various heights**. A double bar graph is made in the same manner that a single bar graph is made except that instead of one bar of data there will be two bars of data.

## What is the use of scatter diagram?

A scatter diagram **visualizes the relationship between two variables**. A scatter diagram is one of the best tools to show a non-linear pattern. A scatter diagram provides the data to confirm a hypothesis that two variables are related.

## How do you describe a scatter graph?

A scatter plot (aka scatter chart, scatter graph) **uses dots to represent values for two different numeric variables**. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.

## What is a linear graph?

Linear means straight and a graph is a diagram which shows a connection or relation between two or more quantity. So, the linear graph is nothing but **a straight line or straight graph which is drawn on a plane connecting the points on x and y coordinates**.

## What do circle graphs show?

A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show **the results of an investigation in a proportional manner**. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.

## What is a histogram graph used for?

The histogram is a popular graphing tool. It is used **to summarize discrete or continuous data that are measured on an interval scale**. It is often used to illustrate the major features of the distribution of the data in a convenient form.

## What’s a horizontal bar graph?

A horizontal bar chart is **a graph in the form of rectangular bars**. It's a data visualization technique. The length of these bars is proportional to the values they represent. The bar chart title indicates which data is represented.

## What is vertical bar graph?

A vertical bar graph is **the most common type of bar chart and it is also referred to as a column graph**. It represents the numerical value of research variables using vertical bars whose lengths are proportional to the quantities that they represent.

## What is XY scatter chart?

Often referred to as an xy chart, a scatter chart **never displays categories on the horizontal axis**. A scatter chart always has two value axes to show one set of numerical data along a horizontal (value) axis and another set of numerical values along a vertical (value) axis.

## What are the 3 types of scatter plots?

**What are the Three Types of Scatter Plot?**

- Positive Correlation.
- Negative Correlation.
- No Correlation (None)

## What is a linear scatter plot?

Scatterplots with a linear pattern have **points that seem to generally fall along a line** while nonlinear patterns seem to follow along some curve. Whatever the pattern is, we use this to describe the association between the variables.

## What is a correlation graph?

Also called: scatter plot, X-Y graph. **The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them**. If the variables are correlated, the points will fall along a line or curve. The better the correlation, the tighter the points will hug the line.

## What is quadratic graph?

Quadratic graphs are **graphs of quadratic functions** – that is, any function which has x 2 x^2 x2 as its highest power. We can plot the graph of a quadratic function by drawing a table of values for the x and y coordinates, and then plotting these on a set of axes.

## What is a parabola graph?

A parabola graph **depicts a U-shaped curve drawn for a quadratic function**. In Mathematics, a parabola is one of the conic sections, which is formed by the intersection of a right circular cone by a plane surface. It is a symmetrical plane U-shaped curve.

## What does the pie graph present?

A pie chart, sometimes called a circle chart, is **a way of summarizing a set of nominal data or displaying the different values of a given variable** (e.g. percentage distribution). This type of chart is a circle divided into a series of segments. Each segment represents a particular category.

## What is a histogram used for?

The histogram is a popular graphing tool. It is used **to summarize discrete or continuous data that are measured on an interval scale**. It is often used to illustrate the major features of the distribution of the data in a convenient form.

## What do you use a circle graph for?

A circle graph, or a pie chart, is used **to visualize information and data**. A circle graph is usually used to easily show the results of an investigation in a proportional manner.

## What is vertical and horizontal bar graph?

Bar graphs consist of two axes. On a vertical bar graph, as shown above, **the horizontal axis (or x-axis) shows the data categories**. In this example, they are years. The vertical axis (or y-axis) is the scale.

## What is Polar chart?

Polar charts are **circular charts that use values and angles to show information as polar coordinates**. Polar charts are useful for showing scientific data. You can specify a default measure. For example, you might need to specify a default measure to give context to a calculated measure in the chart.

## What is an XY graph called?

_The modern Cartesian coordinate system in two dimensions (also called a **rectangular coordinate system**) consists of two axes called the x (horizontal) and y (vertical) axes.

## What is scatter plot used for?

Scatter plots are used **to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another**. Each row in the data table is represented by a marker whose position depends on its values in the columns set on the X and Y axes.

## Which of the following plots can be used to show the relationship between two quantitative variables 1 box plot 2 line plot 3 scatter plot 4 histogram?

**Scatter plots** are used to show the relationship between two variables.

## What is a nonlinear graph?

Non-linear means **the graph is not a straight line**. The graph of a non-linear function is a curved line. A curved line is a line whose direction constantly changes. A cautionary note: Economists are accustomed to designate all lines in graphs as curves – both straight lines and lines which are actually curved.

## What type of graph is best for showing a relationship between two variables?

**Scatter charts** are primarily used for correlation and distribution analysis. Good for showing the relationship between two different variables where one correlates to another (or doesn't). Scatter charts can also show the data distribution or clustering trends and help you spot anomalies or outliers.

## What are scatter graphs used for?

Scatter plots are used **to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another**. Each row in the data table is represented by a marker whose position depends on its values in the columns set on the X and Y axes.
