Question
What type of correlation do the data in the graph show?A.Negative correlationB.No correlationC.Perfect correlationD.Positive correlation
Solution
To determine the type of correlation shown by the data in the graph, follow these steps:
-
Examine the Trend: Look at the overall direction of the data points in the graph. Are they moving upwards, downwards, or scattered without any clear direction?
-
Identify the Slope:
- If the data points trend upwards from left to right, this indicates a positive correlation.
- If the data points trend downwards from left to right, this indicates a negative correlation.
- If the data points do not show any clear trend and are scattered randomly, this indicates no correlation.
- If the data points form a perfectly straight line, either upwards or downwards, this indicates a perfect correlation.
-
Match with Options:
- A. Negative correlation: Data points trend downwards.
- B. No correlation: Data points are scattered without any clear trend.
- C. Perfect correlation: Data points form a perfectly straight line.
- D. Positive correlation: Data points trend upwards.
By following these steps, you can determine the type of correlation shown by the data in the graph.

Look at the scatterplot and identify the type of correlation (positive linear correlation, negative linear correlation, non-linear correlation, or no correlation) that is most likely present in the data. If linear correlation exists, identify whether it is perfect, strong, or moderate-weak.https://s3.amazonaws.com/vretta-assignment-assets/ID5731-shs_ch4.1_q6.png
