Scatter Plot Analysis and Trends

The video tutorial covers a scatter plot analysis of the Canadian Football League, focusing on three questions. It examines teams with more than 20 points, those with fewer than 40 touchdowns against them, and discusses the correlation observed in the graph. The tutorial highlights the downward trend in points as touchdowns against increase, suggesting a potential discussion on team strength.

What is the main focus of the scatter plot discussed in section 3.4?

• Number of goals scored by each team

• Number of games won by each team

• Number of penalties in the league

• Number of touchdowns against endpoints for nine teams

How many teams had more than 20 points according to the scatter plot?

• Five teams

• Four teams

• Three teams

• Two teams

What does a dot above the 20-point line on the scatter plot represent?

• A team with more than 20 points

• A team with exactly 20 points

• A team with no points

• A team with fewer than 20 points

How many teams had fewer than 40 touchdowns scored against them?

• One team

• Two teams

• Three teams

• Four teams

What does a dot on the 40-touchdown line indicate?

• The team had no touchdowns

• The team had fewer than 40 touchdowns

• The team had more than 40 touchdowns

• The team had exactly 40 touchdowns

What is the observed trend in the scatter plot as touchdowns against increase?

• Points increase

• Points remain the same

• Points decrease

• Points fluctuate randomly

What is the term used to describe the relationship observed in the scatter plot?

• Downward correlation

• No correlation

• Upward correlation

• Positive correlation

Why might points decrease as touchdowns against increase?

• The team is stronger

• The team is weaker

• The opposing team is stronger

• The opposing team is weaker

What could be a reason for the downward trend in the scatter plot?

• Teams scoring more points

• Teams having fewer touchdowns against

• Opposing teams being stronger

• Opposing teams being weaker

What is the significance of the scatter plot's direction?

• It shows a downward trend

• It indicates a positive trend

• It shows a random pattern

• It indicates no trend
