ScatterPlots

Front

What is a scatter plot?

Back

A scatter plot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What does a negative linear association in a scatter plot indicate?

Back

A negative linear association indicates that as one variable increases, the other variable tends to decrease.

Front

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation implies that one variable directly affects the other.

Front

What type of correlation is shown when the outside temperature increases and the amount of layers worn decreases?

Back

Negative correlation.

Front

What does it mean if a scatter plot shows no correlation?

Back

It means there is no discernible relationship between the two variables being plotted.

Front

How can you identify a linear relationship in a scatter plot?

Back

A linear relationship can be identified if the points in the scatter plot form a straight line or a pattern that closely resembles a straight line.

Front

What is the purpose of using scatter plots in data analysis?

Back

Scatter plots are used to visually assess the relationship between two quantitative variables and to identify trends, patterns, or correlations.

Front

What does a positive correlation look like in a scatter plot?

Back

A positive correlation is indicated by points that trend upwards from left to right, meaning as one variable increases, the other also increases.

Front

What is the significance of the slope in a linear relationship?

Back

The slope indicates the rate of change between the two variables; a steeper slope indicates a stronger relationship.

Front

What does it mean if a scatter plot has a cluster of points?

Back

A cluster of points suggests that there may be a strong relationship or correlation between the variables in that specific range.
