Scatter Plots

Front

What is a scatter plot?

Back

A scatter plot is a graphical representation of two variables where each point represents an observation. It helps to visualize the relationship between the variables.

Front

What does a positive correlation in a scatter plot indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation in a scatter plot indicate?

Back

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

Front

What does 'no association' mean in the context of a scatter plot?

Back

'No association' means that there is no discernible relationship between the two variables represented in the scatter plot.

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatter plot, showing the general direction of the data points.

Front

How can you identify the line of best fit on a scatter plot?

Back

The line of best fit can be identified as the line that minimizes the distance between itself and all the data points in the scatter plot.

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis that typically represents the independent variable in a scatter plot.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable in a scatter plot.

Front

What does it mean if a scatter plot shows a strong correlation?

Back

A strong correlation means that the data points are closely clustered around the line of best fit, indicating a strong relationship between the two variables.

Front

What is an example of a situation that might show a negative correlation?

Back

An example of a negative correlation is the relationship between the age of a car and its value; as the car gets older, its value typically decreases.
