 * Question 1: Look at the given table and recognize the lengths of the alligators **
 * // Part A: // //Using the table based on the length of alligators and create a graph for it//.**

//**Part B: Use Table function to create the table of data.**// __Length and Weight of Captured Alligators__ //**Part C: Find Mean and Median Lengths.**// The Mean is 84.96 in. The Median is 85 in. //**Part D: Find the Range**// The Range is 58-128 in. **Question 2: Contemplate the given weights of the alligators** **//Part A: Using the table based on the weight of the alligators and create a graph for it.//**

**//Part C: Find Mean and Median Weights.//** The mean is 108.2 lbs The Median is 80 lbs **//Part D: Find the Range.//** The Range is 28-640 lbs **Question 3: Discover the Connection between the width and the length of the alligators.**
 * //Part A: Make a Coordinate Graph of data//**



The weight is smaller than the length The weight and length are similar The weight is larger than the length The weight would be slightly less than the length so around 65 The weight is slightly larger than the length so around 110 The weight is double the length so around 260 Yes, you could probably give a close estimate. The smaller the length is the smaller the weight is. Sometimes the length is even double the weight. If you had a middle length, around in the 80's the weight would would be very similar. For the long lengths the weight would be larger the longer you get. Sometimes the weight is even double the length
 * //Part B: What is the connection between length and weight the the alligators that are://**
 * //-61 and 63 inches long?//**
 * //-82, 85 and 86 inches long?//**
 * //-90, 94 and 114 inches long?//**
 * //Part C: What is the weight of an alligator if he is://**
 * //-70 inches long?//**
 * //-100 inches long?//**
 * //-130 inches long?//**
 * //Part D: According to your investigation; would you be able to foretell the weight of an alligator if you know its length?//**

Knowing the mean and median helps because that gives you an idea of what the typical is. And knowing the typical is vital since that is basically the average, standard and also common. Knowing the range helps because it gives you an idea of how large or small the data is. And when analyzing data you sometimes need to make a graph in order to conclude. When making a graph, the range is crucial to the axis; in spacing the numbers out and where to end the graph. //** a. Line Plots **// You generally use a line plot when you want to show the difference or the changes. An example would be that if you wanted to show the difference of buyers from year 1997-2009 a line plot would be ideal. Stem and Leaf Plots are used to display one type of numerical data. It is handy when you want to compare data from two different classes in which case you make a back to back stem and leaf plot in order to compare who did the best. An example would be the back to back stem and leaf plot about the amount of jumps between Mr.K and Mrs.?. Coordinate graphs are used when you want to see the relationship between two types of data. **Problem 4: When you say a persons arm span is //related// to their height, or that the weight of an alligator is //related// to its length; what do you mean?** When you say a persons arm span is related to their height you would mean that their height is the same as their arm span if they are perfect. Related is for the perfect people the difference. In some cases ... is 5* (or 4*,8* the same etc.)the .... In other cases it varies on the numbers like in this alligator case. Just like typical has many meanings or definitions related can be used in many ways. Another one could be that they have some sort of connection.
 * Problem 1: How does knowing the mean and median help in analyzing data? **
 * Problem 2: How does knowing the range help in analyzing the data? **
 * Problem 3: The different types of numerical data are best shown using: **
 * //b. Stem and Leaf Plots//**
 * // c. Coordinate Graphs //**
