## What is the purpose of using scatter diagram?

**Scatter diagrams** are useful to determine the relationship between two variables. This relationship can be between two causes, or a cause and an effect, etc. It can be positive, negative or no relationship at all. The first variable is independent, and the second variable depends on the first.

## What are scatter plots used for in real life?

**Scatter plots** help visually illustrate relationships between two economic phenomena, such as employment and output, inflation and retail sales, and taxes and economic growth.

## Why use a scatter plot instead of a line graph?

As a general rule, **use** a **line chart** when your data includes non-numeric (category) data – if your data contains only numeric values, it is usually better to **use a scatter chart**. The following table may further help you decide which of the two **chart** types is best for your data.

## What type of data is required for a scatter plot?

A scatter plot is a graph created using ordered pairs from bivariate data. Bivariate data is data that involves two **variables**.

## How do you explain a scatter plot?

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 does a scatter plot show?

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 a scatter plot example?

A **Scatter** (XY) **Plot** has points that show the relationship between two sets of data. In this **example**, each dot shows one person’s weight versus their height.

## What are the 3 types of scatter plots?

There are three types of **correlation**: positive, negative, and none (no **correlation**). Positive **Correlation**: as one variable increases so does the other. Height and shoe size are an **example**; as one’s height increases so does the shoe size. Negative **Correlation**: as one variable increases, the other decreases.

## What is a scatter plot and how does it help us?

A **scatterplot** is a **graph** of paired (x, y) quantitative data. It provides a visual image of the data **plotted** as points, which **helps** show any patterns in the data. It provides an organized display of the data, which **helps** show patterns in the data.

## Do you connect the dots on a scatter plot?

**Scatter plots** are similar **to** line graphs in that they start with mapping quantitative data points. The difference is that with a **scatter plot**, the decision is made that the individual points **should** not be connected directly together with a line but, instead express a trend.

## Do you connect the dots on a line graph?

**You connect** the points in a **graph** when all of the values in-between the integers along the x-axis have corresponding y values. For example, in the **graph** y=x^2, every x point has a y point, while for a some cases **you** want only the specific points.

## What is the difference between plot and graph?

Generally, **plot**, as a noun, refers to a set of points that may or may not be connected by a line, but that cannot be represented as a function. So, in short, “**plot**” is used for a finite set of points, while a “**graph**” is used for a function comprised of infinite points.

## What are the two variables in a scatter plot called?

The Two Variables In A Scatter Plot Are Called The: **Independent Variable** And **Dependent Variable**.

## How do you describe a scatter plot with no correlation?

If the points on the **scatter plot** seem to form a line that slants down from left to right, there is a **negative relationship** or **negative correlation** between the variables. If the points on the **scatter plot** seem to be scattered randomly, there is **no relationship** or **no correlation** between the variables.

## How do you know if a scatter plot is weak or strong?

**Strength** refers to the degree of “**scatter**” in the **plot**. **If** the dots are widely spread, the relationship between variables is **weak**. **If** the dots are concentrated around a line, the relationship is **strong**.
