The scatter plot below shows the average traffic volume and average vehicle speed on a certain freeway for 50 days in 1999.
Explain the relationship/correlation you notice on the graph.
Without providing a specific scatter plot or data, I cannot describe the relationship or correlation observed on the graph. However, generally speaking, if we have a scatter plot with average traffic volume on the x-axis and average vehicle speed on the y-axis, the relationship or correlation between these variables can be analyzed by observing the overall pattern or trend in the data points.
If the data points appear to follow a specific direction or trendline, it suggests a relationship between the variables. For example, if the data points cluster around a line sloping upwards from left to right, it indicates a positive correlation, meaning that as the traffic volume increases, the average vehicle speed also tends to increase.
Conversely, if the data points cluster around a line sloping downwards from left to right, it indicates a negative correlation, suggesting that as the traffic volume increases, the average vehicle speed decreases.
If there is no apparent pattern in the data points, it suggests no or weak correlation between the average traffic volume and average vehicle speed.
It is important to note that correlation does not necessarily mean causation, and further statistical analysis would be required to determine the strength and significance of the relationship.
