1a)Make a appropriate graph that shows the data about the length of the alligator and write 1 or 2 sentence.

Length of the alligators

I did this in a stem and leaf plot because this was the easiest thing to do.

1b)What is the mean and the median? The mean is 84.96 and the median is 85

1c)What is the range? The range is from 58 to 147

2a)Make a graph that shows the weight of the alligators?

skip

b)Use the data to create a table


 * Gator Number || Length (in.) || Weight (lbs) ||  || Gator Number || Length (in.) || Weight (lbs) ||
 * 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 ||
 * 11 || 114 || 197 ||  || 24 || 76 || 42 ||
 * 12 || 69 || 36 ||  || 25 || 86 || 90 ||
 * 13 || 86 || 83 ||  ||   ||   ||

c)Find the mean and the median? The mean is 108.2 lbs The Median is 80 lbs

d)What is the range? The Range is 28-640 lbs

3a)Make a coordinate graph of the data of the alligators

b)Relation of alligator's length and weight that are > Weight is smaller than the length > > The length and weight are similar > > The weight is bigger than the length
 * 1) 61 and 63 inches long
 * 82,85 and 86 inches long
 * 90,94 and 114 inches long

c)What is the weight of the alligator if it is > The weight would be a little lesser than the length > > Weight is slightly larger than length > > The eight is X2 the length
 * 1) 70 inches fat
 * 1) 100 inches fat
 * 1) 130 inches fat

d) Would you be able to tell the weight of a alligator if you knew its length I think yes because if the length of the alligator is smaller than its obvious that the weight is small.

Looking back and ahead

1)How does knowing the mean and median help you in a numerical problem? Knowing the mean helps because you know the average of the data and knowing the median helps because to let you know what lies in the middle

2)How would the range help you in a problem? The range helps you in a problem to let you know from what # to what.

3)What graph best show numerical data?
 * 1) **Stem and leaf plot:** Stem and Leaf Plots are used to display one type of data. It is handy when you compare two different data when you make a B2B stem and leaf plot.
 * 2) **Line plot:**This plot is used to show differences or changes of the data.
 * 3) **Scatter plot:**This graph is also called co ordinate graph. This graph is used to compare two data sets.

4) What does it mean when a person says your arm span is related to your height It means that your arm span is the same length as your height. It also could mean what is the connection between your height and arm span.
