QNT 351 Week 2 Team Assignment Descriptive Statistics Real Estate Data Part 1 (New)

FOR MORE CLASSES VISIT www.qnt351mentor.com Search the Internet for a realty site. Select a hometown of someone on your team in the search section on the website you have chosen. When all of the listings populate, make sure that the sort criteria reads "New Listings." This ensures that you are searching a random cross-section of listings rather than favoring one price range. Review the new listings that populate.

Create an ExcelÂŽ spreadsheet with 4 columns of the first 100 single family homes listed, not including condominiums or townhouses. Include each of the following categories in the spreadsheet: Property address, listing price, square footage, and number of bedrooms. Prepare a frequency distribution for listing prices, including relative frequencies. Create your frequency distribution as identified in Chapters 2, 3, and 4. Generate a histogram from your frequency distribution, again making sure you are consistent with the rules discussed in Chapter 2. Summarize your findings from your frequency distribution and your histogram. Create either a pie chart or a bar graph of the number of bedrooms in your 100 homes. Evaluate your visual aid. Calculate measures of central tendency for both listing prices and square footages. Those measures are mean, median, and mode. Determine the quartiles for both listing prices and square footages. Calculate measures of dispersion for both listing prices and square footages. Those measures are range, variance, and standard deviation. Apply Chebyshev's Theorem and the Empirical Rule to both sets of data. Compare your findings with your actual data. Conclude whether Chebyshev's or Empirical Rule is more accurate with each of listing prices and square footages. Format your assignment consistent with APA guidelines.

The frugal farmer wanted to test the new fertilizer before committing the large investment required to fertilize a farm of his size. He therefore selected 15 parcels of land on his property and divided them each into two portions. He bought just enough of the new fertilizer to spread over one half of each parcel and then spread the old fertilizer over the other half of each parcel. His yields in pounds per tomato plant were as follows: What if you were the fertilizer sales representative and your job was to prove the superiority of the new product to the farmer?
