Download Data On A Companys Stock History From This Data Create Sca

Download data on a company's stock history. From this data, create scatterplots, histograms, and calculate the mean, median, mode, and standard deviation of some data points. Write a 3-5-page report including the graphs and descriptive statistics you have created. Business analytics techniques are used to facilitate decision making by transforming large amounts of raw data into meaningful information. Many businesses rely on analysis of relevant historical data to make key strategic and operational decisions.

Therefore, understanding how to use techniques such as graphical representation and descriptive statistics to translate raw data into useful information can be a valuable skill in an organization. In this assessment, you will practice exploring data by downloading a practical dataset of stock prices and creating graphical representations of that data. Your analysis will help develop skills necessary for interpreting and communicating insights derived from business data.

Since the purpose of business analytics is to make sense of large quantities of raw data, this assessment helps you develop skills in applying analytics to business contexts by practicing the exploration and display of data. Descriptive methods can be used to summarize data numerically and visually, providing insights into the data distribution, central tendency, and variability. When analyzing data for a sample, the calculated measures (statistics) serve as estimates of the true population parameters. Confidence intervals can further account for uncertainty in these estimates.

You are an analyst in a publicly traded company, and your supervisor has asked you to analyze the company's stock data and prepare visual and statistical summaries for a quarterly business meeting. You will select a company of interest, download a year's worth of historical stock data from Yahoo! Finance, and generate graphical and descriptive statistics to interpret the data.

Follow these steps: Access Yahoo! Finance, search for your company’s stock, and navigate to the “Historical Data” tab. Set the time period to one year, select “Daily” frequency, and apply. Download the data as an Excel file. Open the file and verify that it contains a full year's data. Save the file for analysis.

Using the Excel data, create the following analyses: a scatterplot of the "High" stock prices over time, a scatterplot of the "Low" stock prices over time, a histogram of the "Adj Close" prices with appropriate bin size, and a histogram of the "Volume" data with suitable bin size. Write a brief explanation of the process used to generate each graph.

Calculate and record the mean, median, mode, and standard deviation for the “Adj Close” prices. Repeat these calculations for the “Volume” data. Provide a brief explanation of how these statistics were computed.

Prepare a report consisting of an APA-formatted title page, an introduction of the company including its background and business context, a section titled "Graphical Representations of Data" with the images and process descriptions, and a section titled "Descriptive Statistics" with the calculated measures and a summary of their computation process. Conclude with proper APA citations for your data source and references.

The report should be between 3 and 5 pages double-spaced, include all graphical and statistical analyses, and be written clearly with proper grammar and mechanics.

Paper For Above instruction

The analysis of stock market data provides crucial insights for making informed business decisions. In this report, I explore the stock data of Apple Inc., a leading technology company renowned for its innovative products and significant market influence. The investigation utilizes a year's worth of historical stock data downloaded from Yahoo! Finance, focusing on key quantitative and graphical analyses to elucidate the stock’s behavior over the period.

Introduction

Apple Inc., founded in 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne, has grown into a multinational technology company headquartered in Cupertino, California. The company's product lineup includes the iPhone, iPad, Mac computers, and services such as iCloud and the App Store. Apple’s stock (AAPL) is one of the most widely traded shares on the NASDAQ stock exchange and often serves as an indicator of technology sector performance. Analyzing its stock performance can provide insights into market sentiment, investor confidence, and the impact of product launches, economic events, or corporate news on its stock prices.

Graphical Representations of Data

Using Microsoft Excel, I created four graphical representations to analyze the stock data: two scatterplots and two histograms. Each visualization was selected to reveal specific data characteristics.

Scatterplot of Highest Stock Prices Over Time

To generate this scatterplot, I first imported the downloaded Excel file into Excel. I selected the "Date" and "High" columns, then inserted a scatterplot via the "Insert" tab, choosing the appropriate XY Scatter plot type. This visualization depicts how the highest daily stock prices fluctuated throughout the year, enabling identification of trends or anomalies.

Scatterplot of Lowest Stock Prices Over Time

Similarly, I created a scatterplot for the "Low" prices over time by selecting the "Date" and "Low" columns and inserting an XY Scatter plot. This graph illustrates the daily minimum stock prices and helps compare fluctuations relative to the "High" prices, providing a comprehensive overview of daily price variation.

Histogram of Adjusted Daily Closing Prices

To analyze the distribution of the adjusted closing prices, I used the "Adj Close" column. I selected this data, accessed the "Insert" tab, and chose the Histogram chart. I adjusted the bin size to ensure the histogram clearly displayed the distribution shape, revealing the central tendency and spread of the closing stock price adjusted for splits and dividends.

Histogram of Stock Trading Volume

For the volume data, I selected the "Volume" column and inserted a Histogram. I adjusted the bin size to visualize the distribution effectively, highlighting periods of high and low trading activity, which could be associated with company-specific news or market-wide events.

Descriptive Statistics

The quantitative analysis of the stock data involved calculating the mean, median, mode, and standard deviation for both the "Adjusted Close" prices and trading volumes. Using Excel functions, such as =AVERAGE(), =MEDIAN(), =MODE.SNGL(), and =STDEV.P(), I derived these measures. The mean provides an average value indicating the central tendency; the median shows the middle value, less affected by outliers; the mode indicates the most frequently occurring value, which can suggest common price points; and the standard deviation quantifies the variability within the data set. These statistics offer a summarized view of the stock's performance and volatility over the period analyzed.

Conclusion

This analysis demonstrated how graphical visualization combined with descriptive statistics can uncover trends and patterns in stock market data. The scatterplots illuminated the temporal fluctuations of the highest and lowest prices, while the histograms revealed the distribution and density of closing prices and transaction volumes. The computed descriptive measures provided quantitative summaries of the data's central tendency and dispersion. Together, these insights can inform strategic investment decisions, risk management, and understanding of market dynamics related to Apple Inc. Therefore, mastering such analytic techniques is vital for business analysts engaged in financial data interpretation.
