Looking Back and Looking Ahead:

Lengths and Wieghts of Captured Alligators (inches) || Wieght (pounds) ||  || Gator Numbers || Lengths (inches) || Weight (pounds) || __**1. Consider and analyze the lengths of the alligators in the table below.**__
 * Gator Numbers || Lengths
 * 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 || 147 || 640 ||

a. I made a stem and leaf plot of the lengths of the captured alligators. The mean was 84.96 inches, the median was 85 inches and the mode was 86 inches. The outliers were 114 inches,128 inches, and 147 inches. The cluster took place from about 55inches to 95inches.
 * A. Make a graph of the lengths of the 25 alligators and write a caption or sentence about the patterns in the lengths**

b. The mean was 84.96 inches and the median was 85 inches
 * B.What are the mean and median lengths?**

c. The range was from 58 to 147 inches.
 * C. What was the range of the lengths?**

__**2. Analyze the weights of these alligators.**__

a. I made a stem and leaf plot of the weights of the captured alligators. The mean was 108.2 pounds, the median was 80 pounds and there was no mode. The outliers were 197 pounds, 366 pounds, and 640 pounds .The cluster took place from about 25 to 130 pounds.
 * A. Make a graph of the weights of the 25 alligators and and write a caption describing it.**

**I COULD NOT FIT WHOLE THING SO THERE ARE THREE PICTURES!!!**

Picture#1:

Picture #2:

Picture #3:

b. The mean is 108.2 pounds and the median is 80 pounds.
 * B.What are the mean and mdedian weights?**

c. The rangle is from 28 to 640.
 * C.What is the range?**

__**3. Finding the relationships between the length and weights of the alligators.**__


 * A. Make a cordinate graph of the data.**

a. ** Length and Weights of Captured Alligators **


 * B. What realtionships do you notice about: **


 * i. 61 and 63 inches long **
 * ii. 82,85, and 86 inches long **
 * iii. 90,94, and 114 inches long **

b.

i. I notice that both their lengths are almost twice the amount of both their wights that were 33 and 44.Both 33 and 44 is multiple of 11. Another thing I found interesting was that even though there was a small difference between the lengths, there was a big difference between the weights. That conpect shows that you cannot figure out the weight of an alligator without knowing the length of it. ii. The range of the weights is not such a big difference, unlike problem one. The lengths in the data do not have such a big difference from the weight of the data. iii. I notice that there are two alligators that are 90 inches long and both the alligators weights are really close. There are two alligators 94 inches long that also have weights that are close together. 114 is an outlier in the data set since it is longer than most alligators.


 * C. What weight would you predict for: **
 * i. 70 inches long? **
 * ii. 100 inches long? **
 * iii. 130 inches long? **

c.

i. I think that a good prediction would be 50 pounds. I think this because almost one out of third of the alligators were less numerically in weight than in length. ii. I think that a good prediction would be 100 pounds. I say this because a lot of the alligators had close wieght to inches. iii. I think that it would be 150 pounds because by length you can tell that this alligator is pretty big, so it will also weigh a lot. d. Yes I do, because most of the alligators had a 20 at max difference from the length. Also you know if it is a big or small alligator by the length. For example I know that a 58 inch alligator will wiegh less than a 147 inch alligator. The mean and median tgives you a vague hint of the range of the data set. The median and mean also gives you a hint of the mode. The mean gives you the average which tells you what most people got close to or got. The median tells you what is in the middle of the data set which tells you that usually the mode is that number or close to it. It will give you a good idea of the mean and median and possible the mode since you know what is generally in between the two numbers and will give you a hint of the amount of things in the problem. I think that a line plot is easiest. It can show you a clear shape that makes it easier to find the median, reange and mode. It only has one axis so you cant coompare and contrast which is good because that usually does not come up on numerical data. A thing to be compared has to be similar to each other and a way where you can relate them to one another. One must give you the answer for the other one to relate to eachother.
 * D. Do you believe from what you have learnt that it is possible to figure out the weight if you know it's length?**
 * __EXPLAINING YOUR REASONING:__** When you analyze a data most of it is visual by shape and that is easiest by graph.
 * 1. How do the mean and median help descrice the number in a data set?**
 * 2. How does the range help you decribe a data set?**
 * 3. What is the best graph for numerical data:**
 * a. line plots**
 * b. stem and leaf plot**
 * c. coordinate graph**
 * 4. How are numerical data related to each other. Like armspan and hieght. Or time to get to school is related to the distance, or the weight of an alligator related to its length?**
