Have you ever wondered how long the average life expectancy for Kentucky is? Well I have been wondering so I decided to find out by working on a project about the average life expectancy in Kentucky. I figured that after I got done then all of the insurance companies that offer life insurance to Kentuckians and even Kentuckians themselves would use this information. First the insurance companies might charge more if the average death age is 80 and you started paying for life insurance when you were 75 because they can only expect around 5 years of payments for like a $100,000 policy then they would be losing money, so to cover the profit lost by raising the monthly payments than if ...view middle of the document...

For instance all of the funeral announcements were doubles to earlier ones.Now that I got the data I have to brake it down into age groups of 10 like the following:30-39=1 40-49=2 50-59=2 60-69=1 70-79=8 80-89=14 90-99=3But for the stem and leaf graph I had to arrange my data in a list from least to greatest like so:33, 42, 44, 58, 58, 60, 70, 71, 73, 73, 74, 74, 75, 79, 80, 81, 81, 82, 83, 83, 83, 84, 87, 88, 88, 88, 89, 89, 90, 90, 91A stem and leaf plot is created by placing the tens digit as a "stem" and the ones digit as a "leaf". You have to separate the ones place with commas so you can tell the numbers apart. For an example please see the diagram below:So the 5 and the 8 would be 58 and the 9 and the one would be 91; but if I was to ad another 9 in the zero column it would stand for just 9.Well a histogram is basically a bar graph and they are really easy to create. For instance all you have to do is below:1. For the following data lets create a histogram called "Life Expectancy in KY" and we will create this histogram with "Bins" or sets of ten such as 0-9 and 10-19 and 20-29, and 30-39 etc:Bins: How many isin that Bin9 019 029 039 149 259 269 179 889 1499 3109 0119 0The bins are basically just like the name, it holds the number that you have so the 39 bin will take any number between 30 to 39 So you can see that across from the 39 there is a 1 to tell you that there was only one piece of data in the range of 30-39. Then the graphs will look at it and call the bar the same name as the bin and make the bar as big as the amount of numbers that fall in the range of that bin.2. And now that I have my data all I have to do is draw out my graph like so:3. And you are done!Now I will show you how to create histogram in Excel:Now I will show you how to create a circle graph by hand.1. Draw a circle. And put a dot in the center and draw a line to the outer edge like so:2. Now do all of the work above but inserting your own numbers. And you should get a graph that looks like:And to create a circle graph using excel all you have to do is what you did for a histogram but change the chart type to a pie chart. Or you can copy you bar graph and right click and click on chart type and change it to a circle graph.Creating a box-and-whiskers plot is fairly easy.All you have to do is find:Min.-1st quartile-Median-3rd quartile-Max.-And once you have that data you need to plot it. The Whiskers are the lines that extend from the boxes. The whiskers start with the min. to the 1st quartile and then from the 3rd Quartile to the maximum (See below for an example). Here is my data:Min.- 331st quartile- 72Median- 803rd quartile- 87.75Max.- 91To create a Box and Whiskers graph on a Ti 83+ Graphing Calculator:1. Turn on your calculator and click on the [STAT] button. (Erase all information that is already on there if need...
