Diya Wiki Assignment 3 Assignment Date: November 8th, 2010 Due Date: December 6th, 2010 Date of submission: November 14th, 2010 Making Graphs using Technology: Data About Us

Make a graph of the lengths of the 25 alligators and write down a sentence describing the distribution of the lengths shown in the graph.

Lengths of Weights and Captured Alligators
 * Gator Number || Length (inches) || Weight (pounds) ||  || Gator Numbers || Length (inches) || Weight (pounds) ||
 * 1 || 74 || 54 ||  || 14 || 88 || 70 ||
 * 2 || 94 || 110 ||  || 15 || 58 || 28 ||
 * 3 || 85 || 84 ||  || 16 || 90 || 102 ||
 * 4 || 61 || 44 ||  || 17 || 94 || 130 ||
 * 5 || 128 || 366 ||  || 18 || 68 || 39 ||
 * 6 || 72 || 61 ||  || 19 || 78 || 57 ||
 * 7 || 89 || 84 ||  || 20 || 86 || 80 ||
 * 8 || 90 || 106 ||  || 21 || 72 || 38 ||
 * 9 || 63 || 33 ||  || 22 || 74 || 51 ||
 * 10 || 82 || 80 ||  || 23 || 174 || 640 ||
 * 11 || 114 || 197 ||  || 24 || 76 || 42 ||
 * 12 || 69 || 36 ||  || 25 || 86 || 90 ||
 * 13 || 86 || 83 ||  ||   ||   ||   ||

What are the mean and median lengths of the Gators?

Median: 85

What is the range of the Gator's lengths? Range: 58-147

Make a coordinate graph



Part B pg 70 What relation do you notice between the weight and the length of the Alligators are 61 and 63 inches long? The Alligators have a weight that is smaller than Alligator's length.

What relation do you notice between the weight and the length of the Alligators that are 82, 85,and 86 inches long? The length and the weight are almost the same.

What do you notice between the weight and length of the Alligator that are 90, 94 and a 114 inches long? The Alligators have a weight that is larger than the Alligator's length.

Part C pg 70 What would you predict the weight for an alligator that is a 70 inches tall? I think the weight would probably be around 50-60 pounds since the weight is slightly smaller.

What do you think the weight for an alligator that is a 100 inches tall? I think the weight would be around a 110-120 since the weight would be slightly larger.

What do you think the weight for an alligator that is a 130 inches tall? I think somewhere around 250-265 since the weight is double the alligator's height.

1.How do the mean and the median help describe the numbers for the data set? I think the mean helps describe the data set because you will be able to find the average weight and length of an alligator. The median helps you find the middle number in an organized group of numbers. You can also get an idea of the typical number. Both the mean and the median can give you a better understanding of the data set.

2. How does the range help to describe the data set? The range helps because you know what the minimum was and what the maximum was. Suppose you are making a graph you need to know the range of the data to make your scale. The range I think also helps you get an understanding of a typical data set.

3. What kinds of numerical data are best displayed with A. line plots? line plots can display a mode very well. I would usually use a line plot when I would be making a graph about the number of paces each student in our class takes to walk 10 meters. B. stem and leaf plots? I would use a stem and leaf plot to compare to data sets. The back to back stem and leaf plot comes very useful there. You can get a quick idea of what you need to know. I would use a stem and leaf plot to record how much time it takes for each student in our class to do wiki assignments. C. Coordinate graphs? I would use a coordinate graph when I would have to show two features of the same thing. Such as I would use a coordinate graph to show the length and weight of each alligator.

4. What do you mean to say when a person's height is related to their arm span or how much time it takes for a person to get to school related to the distance traveled? If the person has the same height and arm span that means they are perfect people. If a person is coming late to school it all depends on when they are getting out of the house, what type of transportation they are using and how much distance the
