Etienne Dogra Wiki Assignment 3 Assignment Date: November 8th, 2010 Due Date: December 6th, 2010 Making Graphs using Technology: Data About Us

1.a Make a graph about the 25 alligators' length and write a sentence describing the length of the alligators shown in the graph

there is one outlier of 147

b. 84.98inches is the mean and 85inches is the median

c.The range is 58-147

2.a Make a graph about the alligators weight and write a sentence describing the graph.

there is a outlier of 366 b.the mean is 108 and the median is 82 c. the range is 44-147

3.a b i. 61 is shorter and heavier but 63 is longer and lighter. ii. 86 is a common length for gators but the over numbers are not. c. i. I would say if a alligator is 70 inches its weight is 60 pounds,ii. if the aligator is 100inch his weight is 90pounds. iii if the length is 130inches the weight is 120 pounds. d. no because you see alligators that have a big difference in weight and length

1. you have a better understanding in numbers and resoning. 2. It helps in knowing about between which numbers are you going to work on. 3. best for line plot would be number and age of kids. best for stem-and-leaf plots would be how long it takes and how far it is from school. best for coordinate graphs would be length vs height.

4. They are related to each over because they are the opposite so it is interesting to compare them.
