# Question: What Do Scatter Plots Show?

## What makes a scatter plot positive?

If the points on the scatter plot seem to form a line that slants up from left to right, there is a positive relationship or positive 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..

## What are the features of a scatter plot?

A scatterplot consists of an X axis (the horizontal axis), a Y axis (the vertical axis), and a series of dots. Each dot on the scatterplot represents one observation from a data set. The position of the dot on the scatterplot represents its X and Y values. Let’s work through an example.

## What does scatter plot mean?

more … A graph of plotted points that show the relationship between two sets of data. In this example, each dot represents one person’s weight versus their height.

## How can you tell if a scatter plot is linear?

Notice that starting with the most negative values of X, as X increases, Y at first decreases; then as X continues to increase, Y increases. The graph clearly shows that the slope is continually changing; it isn’t a constant. With a linear relationship, the slope never changes.

## What is a scatter plot and why is it useful?

Scatter plots’ primary uses are to observe and show relationships between two numeric variables. The dots in a scatter plot not only report the values of individual data points, but also patterns when the data are taken as a whole. … A scatter plot can also be useful for identifying other patterns in data.

## What information does a scatter plot provide?

Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation . Scatter plots usually consist of a large body of data.

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

Scatter plots (also called scatter graphs) are similar to line graphs. A line graph uses a line on an X-Y axis to plot a continuous function, while a scatter plot uses dots to represent individual pieces of data. In statistics, these plots are useful to see if two variables are related to each other.

## How do you interpret a scatter plot?

You interpret a scatterplot by looking for trends in the data as you go from left to right: If the data show an uphill pattern as you move from left to right, this indicates a positive relationship between X and Y. As the X-values increase (move right), the Y-values tend to increase (move up).

## What is a scatter plot example?

Scatter Plots. 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.

## How do you do a scatter plot?

Use a scatter plot when you have two variables that pair well together. If you have two variables that pair well together, plotting them on a scatter diagram is a great way to view their relationship and see if it’s a positive or negative correlation.

## How do you name a scatter plot?

Always label what variable is plotted along each axis. These labels should also make clear what units are being used for the variables being plotted. … Put a title above the graph or make a descriptive caption for it (beneath the figure).

## What is a strong scatter plot?

A scatterplot displays the strength, direction, and form of the relationship between two quantitative variables. … The relationship between two variables is generally considered strong when their r value is larger than 0.7.

## What are scatter plots 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.

## What are the 3 types of scatter plots?

With scatter plots we often talk about how the variables relate to each other. This is called correlation. There are three types of correlation: positive, negative, and none (no correlation). Positive Correlation: as one variable increases so does the other.

## Do scatter plots have lines?

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.
