 * 1. Alligators lengths in sample.**


 * a. Make a graph and table to show the lengths of the 25 alligators and write a sentence describing the lengths.**

The alligator lengths show that many of the alligators are kind of different in there lengths. Many of them are around in 80.


 * b. What is the mean and median of the alligator lengths?**

The median is 85 inches. The mean is 84. 96 inches.


 * c. What is the range of the alligator lengths?**

The range is 89 inch because 147 inches - 58 inches = 89 inches.


 * 2. a. Make a graph and table with the weight of the alligators. Write a sentence to describe the graph**
 * Alligator Number || Weight(in pounds) ||
 * 1 || 54 ||
 * 2 || 110 ||
 * 3 || 84 ||
 * 4 || 44 ||
 * 5 || 366 ||
 * 6 || 61 ||
 * 7 || 84 ||
 * 8 || 106 ||
 * 9 || 33 ||
 * 10 || 80 ||
 * 11 || 197 ||
 * 12 || 36 ||
 * 13 || 83 ||
 * 14 || 70 ||
 * 15 || 28 ||
 * 16 || 102 ||
 * 17 || 130 ||
 * 18 || 39 ||
 * 19 || 57 ||
 * 20 || 80 ||
 * 21 || 38 ||
 * 22 || 51 ||
 * 23 || 640 ||
 * 24 || 42 ||
 * 25 || 90 ||

In the plot there are 3 outliers. 197, 366, and 640 inches. There are few alligators who weight around 80-84 pounds.


 * b. What is the mean and median of the alligator weight.**

The mean is 108.2 pounds. The median is 80 pounds.


 * c. What is the range of the alligator weight.**

The range is 28 - 640. So it is 612 pounds.


 * 3.**
 * a. Make a coordinate graph of the weight and height of the alligators.**




 * b. What is the connection the weight and length of these alligators:**

The length is bigger than the weight. The weight is similar to the length. The weight is more than the length.
 * 61 inches and 63 inches long**
 * 82,85, and 86 inches long**
 * 90,94, and 114**

The weight could be around 50-60 pounds. The weight could be 120 pounds. The weight could be 240 pounds.
 * c. What is the weight of the alligatior if it is:**
 * 70 inches long**
 * 100 inches long**
 * 130 inches long**

Yes because it depends on the weight and length. Sometimes the length and weight can be nearby but sometimes the weight can be doubled.
 * d. Based on the investigation you did on the alligator weights and heights is it possible to estimate the weight if you know the length?**

The mean can show the average of the data so it can be useful. Knowing the median can also help because you can know what number is in the middle. Then you can also know the higher and lower numbers.
 * 1. How can the median and mean describe numbers in a set of data?**

The range is from the lowest data value to the highest. That can help you to know how big the data is.
 * 2. How can the range describe numbers in a set of data?**


 * 3. What is numerical number best displayed in:**
 * a. line plots b. stem-leaf-plots c. coordinate graphs**

a.line plots- Line plots are best for things like food, drinks, and books.

b. stem and leaf plots- Data that only displays one type of data.

c. coordinate graphs- Coordinate graphs are best displayed with that have data like length and weight etc.


 * 4. What does it mean to have a person's armspan is related to the person's height or how much time it takes to get to school is related to the distance of getting to school or that the weight of an alligator is related to the alligator's length?**

The things are related because they are connected. The armspan and height is related because it has to do with how long you armspan is and how long you are.
