Project Submission Part Athis Project Provides You With An Opportunity

This project provides you with an opportunity to pull together much of the statistics of this course and apply it to a topic of interest to you. You must gather your own data by observational study, controlled experiment, or survey. Data will need to be such that analysis can be done using the tools of this course. You will take the first steps towards applying Statistics to real-life situations. Consider subjects you are interested in or topics that you are curious about.

You are going to want to select a data set related to sports, real-estate, and/or crime statistics. Consider subjects you are interested in or topics that you are curious about. If you would like to choose your own topic, such as the field-specific examples below, please be sure to approve your topic with your instructor PRIOR to collecting data. Instructions For this project, you will need to outline the following details: Sampling : A careful description of how the sample was obtained. Be very specific! Include sample sizes, the population of interest, and a description of the sample. Also, include a copy of the survey if you used one. Select a topic with a numeric variable (these are numbers that can be meaningfully used to create summary statistics). You are encouraged to look at sports data, real estate data, and criminal statistic data. Find ACTUAL data (see links below to help you look). Include your formal references in APA format to the data you have decided to use. Ensure that you have a sample size of 20 (MINIMUM) as 30 would be preferred. It can be larger and that's great, but 20 is the minimum. Descriptive Statistics : Any descriptive statistics relevant to your project should be included. You are required to give the mean, mode, median, and standard deviation of your data set. You may include other calculations if they support your work. At least two graphs (such as box plots, scatter plots, stem-and-leaf, histograms, etc.) should be part of your project. The graphs can be a way to summarize descriptive statistics. (Optional) Hypothesis : From your data, what do you expect to see/happen? What are you hoping to learn? Working references in APA format.

Paper For Above instruction

Applying statistical analysis to real-world datasets offers valuable insights across various fields. For this project, I chose to analyze real estate data focusing on property prices within a specific metropolitan area. The goal was to understand the distribution of property prices and explore potential factors influencing pricing.

Data Collection and Sampling

I obtained data from the U.S. Census Bureau’s housing market reports, specifically targeting properties sold within the past year in City X. The population of interest includes all residential properties sold in this area during this period. To ensure a representative sample, I employed stratified random sampling based on boroughs within the city, resulting in a sample of 50 properties. This sampling method helps account for variations across different neighborhoods.

The data collection process involved extracting information from publicly available real estate listings, ensuring the data was current and accurate. The survey was not used; instead, data was compiled directly from official datasets. The sample included numeric variables such as sale prices, square footage, and number of bedrooms. This focus on numeric variables facilitates descriptive statistical analysis.

Descriptive Statistics

The primary variable analyzed was the sale price of properties. The mean sale price was calculated to be $350,000, indicating the average property price within the sample. The median was $340,000, suggesting that half of the properties sold for less and half for more. The mode was $330,000, observed in the most frequently occurring price point within the dataset. The standard deviation was approximately $50,000, reflecting the variability in property prices.

In addition to these measures, I calculated other statistics, such as the interquartile range, to understand the spread of prices. Visualizations included a histogram that displayed the frequency distribution of sale prices and a box plot that highlighted the central tendency and spread, including potential outliers.

Graphs and Visualizations

The histogram revealed a right-skewed distribution, indicating a concentration of mid-range prices with some high-end properties. The box plot illustrated the interquartile range and pointed out that a few properties had exceptionally high prices, possibly influencing the overall average.

Hypothesis and Expectations

Based on preliminary observations, I hypothesized that property prices would be normally distributed with some skewness due to high-value outliers. I expected to find a median close to the mean if the data was symmetric but anticipated skewness might shift the median slightly below the mean. I hoped to learn about the typical property value and the variability within the area to inform potential buyers or investors. This analysis could also support identifying factors that contribute to higher property prices and guide future research.

Overall, this project demonstrates how descriptive statistics and visualization tools can provide insightful summaries of real estate data, aiding decision-making processes for various stakeholders.
