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

Data For Graph I think that there is a pattern because in the graph, it goes Up and Down 1.B- What are the mean and median lengths? The mean is 84.96 The median is 85 1.C- What is the range of the data? The range is 58-147. 2.A- Make a graph of the weights of the 25 alligators and write a sentence describing the distribution of weights shown in the graph. 2.B- What are the mean and median for this data? The mean is 108.20 The median is 80. 2C- What is the range of the weights? The range is 28-640 3A- Make a coordinate graph of the (weight,length) data ???? 3B- What relationship do you notice length and weight of the alligators? i.61 and 63 inches long ii.82,85 and 86 inches long 111. 90,94 and 114 inches long. I notice that the difference between the weight and the length are not that much and that it depends on how long the length is for the weight. 3C- What weight would you predict for an alligator that is i.70 inches long ii.100 inches long iii. 130 inches long I predict that the 70 inches one is 84 pounds I predict that the 100 inches one is 124 pounds I predict that the 130 inches one is 150 pounds. 3D- Based on your study of the alligator length and weight data, do you believe it is possible to make a good estimate for the weight of an alligator if you know its length? No because there is absolutely no pattern in the data that we have studied. 1. How do the mean and median help in describing the numbers in the data set? The mean helps describe what the average is in that data table so it gives an idea of what is one of the most common (average). The median shows what the highest number is in that data table so you get an idea of what is the most common. 2. How does the range help in describing the numbers in the data set? The range shows the least number and the highest number in the data set so know what the data set starts with and ends with if it is not organized. 3. What kinds of numerical data are best displayed with a. line plots? b. stem-and-leaf plots? c.coordinate graphs? For line plots the best numerical data showed are the number of people in a household or the number of people going out ETC. For stem and leaf plots the best numerical data showed are the number of people did this and things like that. For a coordinate graph the best numerical data is like a time management chart. 4. What does it mean to say that a person's arm span is related to his or her height, or that the time it takes to travel to school is related to the distance traveled, or that the weight of an alligator to it's length? That one thing is compared to the other like if we say the distance traveled to school is related to the time it takes for you to come to school is comparing.
