Tabeeb Wasit-MATH-6-G Wiki Assignment 3 Assignment Date: 8th November, 2010 Due Date:December 6th, 2010 Making Graphs Using Technology: Data About Us

//1) Consider the lengths of the alligators in the sample.//

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

B. What are the mean and median length? The mean is the average so basically you just have to add all the lengths of the alligators up and then divide by the number of alligators there are and the mean I found is: 84.96. The median is like the middle number and the median I found is: 85. C. What is the range of the data? The range of the data is 58 to 147.

2) a. (I made a bar graph and it is up in the data with the length and weight). b. The mean is basically the average so basically you just to add all the wights of the alligators up and then divide by how many alligators there are and the mean I found is: 108.2. The median is like the middle number and the median I found is: 80. c.The range of the data is 28 to 640.

3) a) b) c) d)

Explain your reasoning- When you describe a collection of data, you look for the shape of the distribution of the data. You can often visualize data patterns using graphs. 1)How does the mean and the median help in describing the numbers in a data set? It gives the person looking at the graph more information. 2)How does the range help in describing the numbers in a data set? It gives the person looking at the graph more information. 3)What kinds of numerical data are best displayed in with a. line plots? stem- and- leaf plots? coordinate graphs? a)In line plots its very easy to understand the information and it's even very easy to make one. b)Stem and leaf plots are even really easy to understand and even to make. c)I think a coordinate graph is pretty difficult to understand because you might get confused because it's not very neat but it shows data and it shows data in the most useful way in all three of these ideas of graphs because of the line in the middle.

4)What does it mean to say that a person's arm span is related to his or her height, or that the time its takes to travel to school is related to the distance traveled, or that the weight of an alligator is related to its length? It means that there is a kind of a pattern in the. Or it even might mean that you can find something easily by doing math. Basically, it means that you can find your height by figuring out your arm span so its kind of like scientific math.
