Constructing Scatter Plots from Bivariate Data

What is the purpose of constructing scatter plots?

• To create artistic patterns

• To determine associations or trends

• To calculate exact numerical values

• To memorize data points

What types of associations are we looking for in scatter plots?

• Circular and triangular

• Positive, negative, or none

• Primary and secondary

• Solid and liquid

What does a positive association in a scatter plot indicate?

• As one variable increases, the other decreases

• Both variables increase together

• Both variables decrease together

• As one variable decreases, the other increases

What can be inferred if a scatter plot shows no association?

• There is no relationship between the variables

• The variables are directly related

• The variables are inversely related

• There is a strong correlation

In the context of scatter plots, what does 'no association' imply?

• The variables move in opposite directions

• The variables move in the same direction

• There is no discernible pattern between the variables

• There is a clear linear relationship

How does an increase in height relate to arm span according to the scatter plot?

• No relation

• Random changes in arm span

• Decrease in arm span

• Increase in arm span

What does the scatter plot fail to show between the number of turns and miles driven?

• A positive linear relationship

• A negative linear relationship

• Any kind of association

• A non-linear relationship

What does a negative association in a scatter plot suggest?

• As one variable increases, the other also increases

• There is no relationship between the variables

• As one variable decreases, the other also decreases

• As one variable increases, the other decreases

What was observed in the scatter plot regarding hours on YouTube and schoolwork?

• No change in schoolwork hours with YouTube usage

• Random fluctuations in schoolwork hours

• More hours on YouTube, less hours on schoolwork

• More hours on YouTube, more hours on schoolwork

What does it mean if a scatter plot is linear?

• The data points form a parabolic shape

• The data points are randomly distributed

• The data points form a straight line

• The data points form a circular shape
