Research on the difference between Data Analytics and Data Science and describe in your words. Find 15 or more analytics / data science related job titles and write one sentence about the primary job responsibility of each of them. The post should be 500 words or more

Discussion: 

Consider the mean of a cluster of objects from a binary transaction data set.

1. What are the minimum and maximum values of the components of the mean?

2. What is the interpretation of components of the cluster mean?

3. Which components most accurately characterize the objects in the cluster?

Please clearly LIST your response out to all THREE (3) questions and ensure to cite the specific article with the binary transaction of data set. I will be examing this for myself and other students should verify this as well. Provide the Author, YYYY  and specific page number, with any content brought into the discussion.

Assignment: 

Answer the following questions in a point by point fashion.  NOT an essay. Please ensure to use the Author, YYYY APA citations with any content brought into the assignment.  

1. For sparse data, discuss why considering only the presence of non-zero values might give a more accurate view of the objects than considering the actual magnitudes of values. When would such an approach not be desirable?
2. Describe the change in the time complexity of K-means as the number of clusters to be found increases.
3. Discuss the advantages and disadvantages of treating clustering as an optimization problem. Among other factors, consider efficiency, non-determinism, and whether an optimization-based approach captures all types of clusterings that are of interest.
4. What is the time and space complexity of fuzzy c-means? Of SOM? How do these complexities compare to those of K-means?
5. Explain the difference between likelihood and probability.
6. Give an example of a set of clusters in which merging based on the closeness of clusters leads to a more natural set of clusters than merging based on the strength of connection (interconnectedness) of clusters.

   When  law enforcement becomes involved, the need may arise to freeze systems  as part of the evidence. There is also the likelihood that the incident  will become known publicly. Do you think these issues play a significant  part in the decision to involve law enforcement? Why or why not? Can  you name some situations in which you believe that large organizations  have decided not to involve law enforcement?    ***Standard for all Research Assignments   Your paper should meet the following requirements:   

• Be approximately four to six pages in length, not including the required cover page and reference page.
• Follow APA7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support  your answers with the readings from the course and at least two  scholarly journal articles to support your positions, claims, and  observations, in addition to your textbook. The UC Library is a great  place to find resources.
• Be  clearly and well-written, concise, and logical, using excellent grammar  and style techniques. You are being graded in part on the quality of  your writing.

A best practice is to thoroughly document the lifespan of a firewall. A firewall implementation procedure should prescribe the systematic process to install and configure a firewall properly. Anytime the firewall is modified, the documentation should be updated accordingly.

Answer the following question(s):

Assuming you would rarely need to reinstall a firewall, why do you think such thorough documentation is needed for installation?

• Why is there a need for data access control?
• What are the benefits and risks for using Smart Cards and PKI?
• How do Smart Cards/PKI protect the data’s confidentiality, integrity, authentication, and non-repudiation?

Exp19_Excel_Ch03_ML1_Airports

Project Description:

As an analyst for the airline industry, you track the number of passengers at the top six major U.S. airports: Atlanta (ATL), Chicago (ORD), Los Angeles (LAX), Dallas/Fort Worth (DFW), Denver (DEN), and New York (JFK). You researched passenger data and created a worksheet that lists the number of total yearly passengers at the top six airports. To prepare for an upcoming meeting, you will create a clustered column chart to compare the number of passengers at each airport. Then, you will create a line chart that compares trends over time. Next, you will create a bar chart to compare the passenger count for the latest year of data available and then emphasize the airport with the largest number of passenger traffic. Finally, you want to insert sparklines to visually represent trends in passengers at each airport over the 10-year period.

Start   Excel. Download and open the file named Exp19_Excel_Ch03_ML1_Airports.xlsx. Grader has automatically added   your last name to the beginning of the filename.

You want to create a clustered   column chart to depict the passenger counts at the six airports over several   years.
  Use Quick Analysis to create a clustered column chart for the range A4:L10.   Cut the chart and paste it in cell A15.

You want to customize the column   chart with a chart title, display the years as a data series, enlarge the chart   to be easier to read, and apply a chart style.
  •Type Passengers   by Top U.S. Airports   as the chart title.
  •Swap the data on the category axis and in the legend.
  •Set a 3.5″ height and 11.4″ width.
  •Apply the Style 7 chart style.

The value axis takes up a lot of   space for the numbers. You will adjust the value axis to simplify it.
  •Change the display units to Millions for the value axis.
  •Edit the axis title to display Millions of Passengers.

You want to focus on the 2016 data   series by adding data labels.
  Display data labels above the columns for the 2016 data series only.

Applying a fill color to the   chart area will make the chart visually appealing.
  Apply the Light Gradient – Accent 2 preset gradient fill to the chart area.

A best practice is to add Alt   Text to a chart for accessibility compliance.
  Add Alt Text: The chart displays the number of passengers in millions   for the top six airports from 2006 to 2016. (including the period).

When you change the workbook   theme, Excel applies that theme to the chart styles.
  Change the workbook theme to Slice.

You want to create a bar chart   to display passenger counts for only one year.
  Create a recommended clustered bar chart for the range A5:A10 and L5:L10 and move   the chart to a chart sheet named Bar Chart.

You want to customize the bar   chart.
  •Change the chart color to Colorful Palette 3.
  •Enter Passengers   at Top 6 U.S. Airports in 2016 as the chart title.
  •Apply the Style 5 chart style.
  •Add Alt Text: The bar chart shows passengers at Top 6 U.S. Airports   in 2016. Atlanta had the most passengers. (including the period).

Modifying the axes will improve   readability of the bar chart.
  •Change the font size to 10 for the category axis and value axis.
  •Change the value axis Maximum Bound to 1.1E8.

You will format a data point so   that it stands out and then add gridlines to enhance readability in the bar   chart.
  •Format the Atlanta data point with Dark Blue, Text 2 fill color.
  •Add Primary Minor Vertical gridlines.

A line chart effectively shows   trends over time for the passenger counts at the different airports.
  Create a line chart using the range A4:L10 in the Passenger worksheet and   move the chart to a chart sheet named Line Chart. Add a chart title Passengers   at U.S. Airports 2006-2016 and bold the title.

You want to customize the line   chart.
  •Set the Minimum Bound at 4.0E7 for the value axis. The Maximum Bound should change to 1.1E8   automatically.
  •Set the Vertical (Value) Axis Display units to Millions. Delete the Vertical   (Value) Axis Display Units Label from the upper-left corner of the chart. Add   a value axis title In Millions.
  •Change the font size to 10 for the value axis and category axis.
  •Move the legend to the top.
  •Filter the chart by deselecting the odd-numbered years.
  •Add Alt Text: The line chart displays trends for top six U.S.   airports from 2006 to 2016 at two-year intervals. (including the period).
