is a sample of Web server statistics for a computer science department. It contains the following eleven sections of data:
- Total successful requests
- Average successful requests per day
- Total successful requests for pages
- Average successful requests for pages per day
- Total failed requests
- Total redirected requests
- Number of distinct files requested
- Number of distinct hosts served
- Corrupt logfile lines
- Total data transferred
- Average data transferred per day
Write an essay of 2–3 pages that contains the following:
- A complete overview of the data, identifying anomalies in different weeks, and the weeks that the data are not regular.
- Choose 5 different sections of data, and examine these sections and provide the specific selection process and criteria you used to select this data set.
- Provide the measures of tendency and dispersion for each of the 5 different sections of data you selected.
- Provide 1 chart or graph for each of the 5 processed sections. This may be a pie or bar chart or a histogram.
- Label the chart or graph clearly.
- Explain why the graph you provided gave a good visual representation of the data.
- Based on your explanation above, identify some specific advantages why, in general, charts and graphs are important in conveying information in a visual format.
- Determine the standard deviation and variation, and explain their importance in statistical analysis of a data set.
- Based on the tasks you performed in this project, research how statistics are used in information technology (IT), and provide references for your research
