Scatterplot Savvy

Plot the point (3, 4) on a coordinate plane. Where does it lie?

• In the first quadrant

• In the second quadrant

• In the third quadrant

• In the fourth quadrant

Which point is closest to the origin?

• (1, 2)

• (2, 3)

• (3, 1)

• (0, 4)

If a scatterplot shows a collection of points in a straight line going from the bottom left to the top right, what kind of correlation does it indicate?

• Positive correlation

• Negative correlation

• No correlation

• Cannot be determined

What is the purpose of drawing a line of best fit on a scatterplot?

• To predict new values

• To connect all the dots

• To make the plot look neat

• To separate different data groups

When drawing a line of best fit by hand, what is the most important aspect to consider?

• The line must pass through every point

• The line should have an equal number of points on either side

• The line should pass through the origin

• The line must be perfectly straight

If a scatterplot's points are widely scattered with no apparent pattern, what type of correlation is this?

• Strong positive correlation

• Strong negative correlation

• Weak or no correlation

• Perfect correlation

What does it mean if the points on a scatterplot are close to the line of best fit?

• There is a weak correlation between the variables

• There is a strong correlation between the variables

• The variables are not related

• The line of best fit is incorrect

If the line of best fit has a slope of zero, what does this indicate about the relationship between the variables?

• Positive correlation

• Negative correlation

• No correlation

• Perfect correlation

How do you determine the slope of the line of best fit in a scatterplot?

• By finding the ratio of the rise over the run between two points on the line

• By counting the number of points above the line

• By measuring the distance from the origin to the line

• By drawing a circle around the line

If a scatterplot shows a downward trend as the x-values increase, what type of slope does the line of best fit have?

• Positive slope

• Negative slope

• Zero slope

• Undefined slope
