Scatterplot Vocabulary Words

What does it mean to interpret a scatterplot in math?

• Analyzing the relationship between two variables by looking for patterns or trends in the plotted points.

• Drawing a line through the plotted points

• Ignoring the plotted points and focusing on the axes

• Counting the number of points on the scatterplot

How is correlation defined in the context of scatterplots?

• It measures the size of the data points in the scatterplot

• It calculates the average of the two variables in the scatterplot

• It counts the number of data points in the scatterplot

• It measures the strength and direction of the relationship between two variables.

What is the relationship between the variables in a scatterplot with a positive correlation?

• As one variable increases, the other variable also tends to increase

• The variables have a negative correlation

• There is no relationship between the variables

• As one variable increases, the other variable tends to decrease

Explain the relationship between variables in a scatterplot with a negative correlation.

• The variables have no relationship

• The variables have a positive correlation

• The variables have a curvilinear relationship

• The variables have an inverse relationship

In a scatterplot, what does it indicate when the points are widely spread out?

• Strong positive correlation

• Negative correlation

• Weak or no correlation

• Perfect correlation

Describe the relationship between the variables in a scatterplot with no correlation.

• There is no relationship between the variables.

• The variables have a strong negative correlation

• The variables have a strong positive correlation

• The relationship between the variables is unclear

What is the significance of the line of best fit in a scatterplot?

• It is used to label the axes in the scatterplot

• It shows the trend or relationship between the variables in the scatterplot.

• It represents the average of the variables in the scatterplot

• It indicates the highest point in the scatterplot

How does the strength of the correlation in a scatterplot affect the relationship between the variables?

• It has no effect on the relationship between the variables.

• It indicates the degree of relationship between the variables.

• It indicates the number of outliers in the data set.

• It shows the direction of the relationship between the variables.

Explain the concept of outliers in scatterplots.

• Outliers have no impact on the overall trend of a scatterplot.

• Outliers are always located at the center of a scatterplot.

• Outliers are perfectly aligned with other data points in a scatterplot.

• Outliers are significantly different from other data points in a scatterplot.
