Question

problem 1
the following data set represents measurements of two related variables in an experiment.
construct a scatterplot.
blank graph with grid

Explanation:

Step1: Identify x and y values

The data pairs are: (10, 8.90), (7, 7.24), (14, 8.95), (8, 7.80), (11, 9.10), (6, 5.95), (5, 4.60), (12, 8.85), (9, 7.90), (4, 3.40).

Step2: Set up the scatterplot grid

The x - axis (horizontal) has values from 3 - 14 (as per the grid) and the y - axis (vertical) has values from 3 - 10 (as per the grid).

Step3: Plot each data point

• For (10, 8.90): Find x = 10 on the x - axis and y = 8.90 on the y - axis, mark the point.
• For (7, 7.24): Find x = 7 on the x - axis and y = 7.24 on the y - axis, mark the point.
• For (14, 8.95): Find x = 14 on the x - axis and y = 8.95 on the y - axis, mark the point.
• For (8, 7.80): Find x = 8 on the x - axis and y = 7.80 on the y - axis, mark the point.
• For (11, 9.10): Find x = 11 on the x - axis and y = 9.10 on the y - axis, mark the point.
• For (6, 5.95): Find x = 6 on the x - axis and y = 5.95 on the y - axis, mark the point.
• For (5, 4.60): Find x = 5 on the x - axis and y = 4.60 on the y - axis, mark the point.
• For (12, 8.85): Find x = 12 on the x - axis and y = 8.85 on the y - axis, mark the point.
• For (9, 7.90): Find x = 9 on the x - axis and y = 7.90 on the y - axis, mark the point.
• For (4, 3.40): Find x = 4 on the x - axis and y = 3.40 on the y - axis, mark the point.

Answer:

The scatterplot is constructed by plotting the points (10, 8.90), (7, 7.24), (14, 8.95), (8, 7.80), (11, 9.10), (6, 5.95), (5, 4.60), (12, 8.85), (9, 7.90), (4, 3.40) on the given grid with x - axis (3 - 14) and y - axis (3 - 10).
