Each of the scatter plots show a strong relationship. Write a sentence or two describing how you think the variables are related.

1.  

   

   A scatterplot. Horizontal, from 0 to one point 4, by 0 point 2’s, labeled precipitation in inches. Vertical, from 0 to 1, by 0 point 1’s, labeled percentage with jackets. 27 points that represent the data, trend linearly upward and right and a line of best fit is drawn. 11 points clustered above the line and 16 points clustered below the line. First data point approximately begins at 0 comma 0 point 0 1 and last is approximately at 1 point 4 comma 0 point 9.

   During the month of April, Elena keeps track of the number of inches of rain recorded for each day and the percentage of people who come to school with rain jackets on that day.

2.  

   

   A scatterplot. Horizontal, from 0 to 9, by 1’s, labeled time in hours. Vertical, from 0 to 700, by 50’s, labeled percentage with jackets. 23 points that represent the data, trend linearly upward and right and line of best fit is drawn. 9 points clustered above the line and 14 points clustered below the line. First data point approximately begins at 2 point 5 comma 200 and last is approximately at 8 point 5 comma 656.

   A school book club has a list of 100 books for its members to read. They keep track of the number of pages in each book that the members read from the list and the amount of time it took to read each book.

3.  

   

   A scatterplot. Horizontal, from 0 to 200, by 25’s, labeled number of tickets left. Vertical, from 0 to 100, by 10’s, labeled noise level in decibels. 20 points that represent the data, trend linearly slightly downward and right and a line of best fit is drawn. 7 points clustered above the line and 13 points clustered below the line. First data point approximately begins at 0 comma 85 and last is approximately at 185 comma 51.

   A venue hosts holiday parties. On the day of each party, they count the tickets remaining and the noise level at the party.

4.  

   

   A scatterplot. Horizontal, from 0 to 70, by 10’s, labeled height in feet. Vertical, from 0 to 100, by 10’s, labeled number of rings. 23 points that represent the data, trend linearly upward and right and a line of best fit is drawn. 13 points clustered above the line and 10 points clustered below the line. First data point approximately begins at 37 comma 60 and last is approximately at 65 comma 100.

   Pine trees grow in a forest. An arborist measures the height, in feet, of trees in a pine forest and counts the number of rings found in core samples from each tree.
