Part 1
1 What columns do you think might be related to one another? (e.g. - is the number of veterans related to the amount of land-area? Is the population in 2010 related to the population in 2020?) List three possible relationships below.
a. I think that may be related to
b. I think that may be related to
c. I think that may be related to
# scatter-plot :: (Table, Stringlabels, Stringexplanatory, Stringresponse) -> Image
2 Use the Contract above to make a scatter-plot for the first relationship you wrote above. (Use "state" as the label, so that clicking on a point will show you which state you’re looking at.)
a. If there’s a pattern in this scatter-plot, what does that mean? If there isn’t, what does that mean?
b. In your own words, describe the pattern you see in the scatter plot so someone else could sketch it.
3 Make a scatter-plot for the second relationship you wrote.
a. If there’s a pattern in this scatter-plot, what does that mean? If there isn’t, what does that mean?
b. In your own words, describe the pattern you see in the scatter plot so someone else could sketch it.
4 Make a scatter-plot for the third relationship you wrote.
a. If there’s a pattern in this scatter-plot, what does that mean? If there isn’t, what does that mean?
b. In your own words, describe the pattern you see in the scatter plot so someone else could sketch it.
Part 2
Wait to complete this until after diving deeper into statistical relationships!
Revisit the three scatter plots you made and add the following labels to the descriptions you wrote in Question 1:
-
Place an "L" by any relationships that you think might be linear.
-
Place a "P" by any relationships that appear to be positive.
-
Place an "N" by any relationships that appear to be negative.
-
Place an "S" by the strongest-looking relationship.
-
Place a "W" by the weakest-looking relationship.
