Full solution

Q. Estimate the correlation coefficient for this scatterplot.\newlineABC Compary
  1. Check Trend Direction: Look at the scatterplot and see if the points have a positive or negative trend.
  2. Identify Correlation Type: If the points go upwards from left to right, it's a positive correlation. If they go downwards, it's a negative correlation.
  3. Evaluate Linearity: Estimate how close the points are to forming a straight line. The closer they are, the stronger the correlation (closer to 11 or −1-1).
  4. Assess Scatter: If the points are really scattered and don't seem to have any direction, the correlation is weak (closer to 00).
  5. Estimate Correlation Coefficient: Based on the scatterplot, make an educated guess about the value of the correlation coefficient. Let's say it looks pretty strong and positive, so maybe around 0.80.8?
