Looking for Possible Relationships

We can look for potential relationships between quantitative columns by building scatter plots. Let’s see what they reveal.

2 Make a scatter plot comparing pitch speedexplanatory variable and hit speedresponse variable.

  • Does there appear to be a relationship between pitch-speed and hit-speed? If so, describe it.

  • Based on the scatter plot, what hit speed would you predict for a ball pitched at 95mph?

    • Why?

  • How confident are you in your prediction? not at all 1 2 3 4 5 very

3 Make a scatter plot comparing pitch speedexplanatory variable and hit distanceresponse variable.

  • Does there appear to be a relationship between pitch-speed and hit-distance? If so, describe it.

  • Based on the scatter plot, what hit distance would you predict for a ball pitched at 95mph?

    • Why?

  • How confident are you in your prediction? not at all 1 2 3 4 5 very

4 Make a scatter plot comparing bat angleexplanatory variable and hit distanceresponse variable.

  • Does there appear to be a relationship between bat-angle and hit-distance? If so, describe it.

  • Based on the scatter plot, what distance would you predict for a ball hit at an angle of 60 degrees?

    • Why?

  • How confident are you in your prediction? not at all 1 2 3 4 5 very

5 Make a scatter plot comparing bat angleexplanatory variable and hit speedresponse variable.

  • Does there appear to be a relationship between bat-angle and hit-speed? If so, describe it.

  • Based on the scatter plot, what speed would you predict for a ball hit at an angle of 20 degrees?

    • Why?

  • How confident are you in your prediction? not at all 1 2 3 4 5 very
