### Too many data!!!!

I finally finish entering my data into Excel, and it was very time-consuming. It took me about 3 hours to enter 300 data. It was so time consuming because for each city on my list I have to use Google map to find out how far it is from ^{th} quartile, the median, the 75^{th} quartile, and the maximum of my data. So I find an awesome website that helps me with this problem. http://www.stat.unc.edu/teach/rosu/Stat31/E1_43.html is the website that I used. It is so easy to compute the five number summary of a data set. All I have to do is type the word Quartile in the Excel prompt and highlights all my data and voila my five number summary is given to me. As for the box plot, I will use the website that I have found last week. Just a note: a box plot is a graph of the five number summary, and my box plot will show outliers. I also need to find the mean and the standard deviation of my data. I do not remember how to do that in Excel. So again I used the amazing search engine Google to find out how to do this. http://www.gifted.uconn.edu/siegle/research/Normal/stdexcel.htm is a very thorough and good website. It teaches me how to find the mean and the standard deviation step-by-step with picture. Just a note: the mean is the average value of a data set and the standard deviation is a measure of variability or dispersion around the mean. The more spread a data, the higher the standard deviation. I also need to do a one sample t test on my data. A one sample t test is a test that tests the validity of a claim made. It is used for a simple random sample of size *n *from a population that has the Normal distribution with mean and standard deviation. It has the *t *distribution with n-1 degrees of freedom. I use Google to find out about how to do a one sample t test in excel but I could not find anything so I use the official website for Excel. http://office.microsoft.com/en-us/excel/HP052016751033.aspx?pid=CH062528011033 is the website that I used. I have to install the Analysis ToolPak, which took some time and it was confusing. So I use another website http://www.bioss.ac.uk/smart/unix/mbasexc/slides/sl18.htm and it really helps. All in all I am glad that I have finished putting all my data analysis and I am ready to move on to creating a “hot” powerpoint.

### Analyzing Data

### Who Am I Suppose to Present My Data to?

Now that I am done with my data analysis toolbox I need to start looking for someone to present my data to. Since my topic is about tourists, I think I should present my project to the people at the New Orleans Tourist Bureau. So what I did is that I use the Google search engine to find out who is on the staff for New Orleans Tourist Bureau. Well I find out the real name of this tourist bureau is

I also would like to present my information to the Times-Picayune. My information would either be in the Living or Travel section of the newspaper since it is about

### Data Analysis Toolbox Revised

So I have been working on my data analysis toolbox. There is a few more changes I made to it. These changes include talking about how New Orleanians could have a taste of the world right from their hometown. New Orleanians are always talking about going somewhere else to learn about other cultures. But a lot of people from other cultures come to

### Data Collection

I am still in the process of collecting my data. I have collected a lot of data. I think I have collected about three hundred people already. There is one thing I did different last weekend then I did the previous weekends. I ask where my customers are from city and state. Before I just ask what state they are from, but now I also ask what city. By doing this I can be more precise in my data collection. Since I have to calculate the number of miles by using this information, I want to be as precise as possible. This project have really help me to get to know my customers better.
