REAL ESTATE DATA PART 1 1 Real Estate Data Part 1 Tiffany Toro, Vivian Garcia, Annamaria King, and Cheryl Byers QNT/351 March 7, 2016 David Dean Gualco REAL ESTATE DATA PART 1 2 Real Estate Data Part 1 Throughout this paper you will find Team D's analysis on the first 100 single-homes in the Visalia, California area. The property address, listing price, square footage and the number of bedrooms were populated in an excel sheet. Various statistical formulas were applied to the data regarding the single-homes which can be seen below. The frequency distribution shows within a price point how many houses were listed. Below is the frequency distribution created based on the above information. The histogram chart gathers the data from the frequency data that was collected on listing price and creates a chart with no gaps with a continuous nature of the data. Within the pie chart it provides a better look at the list pricing. Chart Title REAL ESTATE DATA PART 1 3 The quartiles, central tendencies and measures of dispersion were fairly easy to find: The data was then analyzed using both the Chebyshev's Theorem and the Empirical Rule to find which provided a more accurate analysis. REAL ESTATE DATA PART 1 4 By using Chebyshev's Theorem and Empirical Rule is more in detail and accurate than the raw data. Chebyshev's Theorem and Empirical Rule breaks down to the percentage of the data collected. Chebyshev's Theorem and Empirical Rule also provides a descriptive statistics for the listings price and the square feet. Using Chebyshev's theorem it allows us to determine the minimum of the value that is within a specified number of standard deviation of the mean (Lind & Marchal, 2015). However, using the Empirical Rule, will allow the mean to be more precise and explain the dispersion about the mean. REAL ESTATE DATA PART 1 5 References Lind, D., & Marchal, W. (2015).
