The OFFICIAL discussion I want you to engage in this week is answering this question: Compared to the person-to-person surveys we did for study one, what are the benefits of using qualtrics and the costs of using qualtrics to do research. Which do you prefer and why? Why is it a good / bad idea to use this online system to collect data? I attached the qualtrics survey

Assignment Content Every developer is focused on transmitting data securely. Hashing and hash functions are essential for securing business information and data. While the term cryptographic hash function may sound intimidating, it’s much simpler than it sounds. For this assignment, expand on the information provided in the course and fully address the items below. Write a 2- to 3-page paper in which you: Define cryptographic hash function (CHF). Elaborate on the main properties and definitions of an ideal cryptographic hash function. Propose 2 business applications or uses for a cryptographic hash function (e.g., password verification) and include a description of how it is used. Format your paper according to APA guidelines.

Requires SPSS to answer the research question. To prepare for this Discussion: Review this week’s Learning Resources and media program related to multiple regression. Create a research question using the Afrobarometer Dataset or the HS Long Survey Dataset, that can be answered by multiple regression. Use SPSS to answer the research question. Post your response to the following: If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). If you are using the HS Long Survey Dataset, report the mean of X1Par1Edu. What is your research question? What is the null hypothesis for your question? What research design would align with this question? What dependent variable was used and how is it measured? What independent variables are used and how are they measured? What is the justification for including these predictor variables? If you found significance, what is the strength of the effect? Explain your results for a lay audience, explain what the answer to your research question. Required Readings Frankfort-Nachmias, C., Leon-Guerrero, A., & Davis, G. (2020).

Courses: STATISTICS FOR DECISION MAKING Question 1:  Find a graph or chart in the news and describe the information provided.  Was this graph the best choice for presenting the data?  Why or why not?  How might the graph mislead the reader, if at all? Please include a screen shot of the graph or chart. (Short Answer). Question2:  Describe the difference between bar charts, histograms, Pareto charts, including how they are structured and in what situations are each most effectively used? (Short Answer).

Respond in your own words in this Discussion forum in 50-100 word responses to the following questions: 1) How do Agile project management approaches relate to traditional (PMI PMBOK) approaches? 2) What is Scrum and how does it relate to Agile methodologies? 3) What are the three main Scrum Roles (or Agile Roles) and how should they serve customer value (what is needed) over constraints (schedule, cost, etc.)? 4) Based on a quick “sweep” of the web (web search), identify and discuss one company or government agency actively using Agile PM (Hint: Search DoD or VA  AND Agile or Scrum for many government hits). Note: Content not coming directly from you will need to be cited per APA. FYI, best practice is to use citations to support your content and assertions. Note: Responses may be a single paragraph or multi-paragraph, but should be well-organized, thorough, and well-presented.

Hello I have 2 Q in Data mining please help me for that : Q1:                                                                           Alzheimer’s disease is a progressive disorder that causes brain cells to waste away (degenerate) and die. Alzheimer’s disease is the most common cause of dementia a continuous decline in thinking, behavioral and social skills that disrupts a person’s ability to function independently. The early signs of the disease may be forgetting recent events or conversations. As the disease progresses, a person with Alzheimer’s disease will develop severe memory impairment and lose the ability to carry out everyday tasks. Current Alzheimer’s disease medications may temporarily improve symptoms or slow the rate of decline. These treatments can sometimes help people with Alzheimer’s disease maximize function and maintain independence for a time. Different programs and services can help support people with Alzheimer’s disease and their caregivers. Refer to the following link to have a brief review for this disease: 20350447   Tasks: –   Build the dataset that would be helped in classifying the level of Alzheimer’s disease. ·      Determine the number and the names of classes that would be used in your experiment (level of Alzheimer’s disease). ·      Determine the best attributes that effect diagnosing this disease. Assign the suitable type for these attributes, make scientific argument for each type  ·      Attach your file (CSV or arff, or Excel) after fill it with 30 records . ·      Perform exploratory data analysis to get a good feel for the data and prepare the data for data mining, supports your answer by add snapshots of the preprocessing part . ·      The task in this dataset is to make predictions of the degree of Alzheimer’s , Which is the suitable filter that supposed to use to select your attributes.  ·      Visualize your attributes. In ?Note: solving this question, there must be an excel file written in the attributes and sent with the solution ·      Smooth your data set using Bin size=3, with all possible methods. Are there any reasons to make this process?

Background  As cybercrimes have become more sophisticated over the years, organizations needed better solutions to prevent and manage threats. Eventually, this leads to full time incident response teams. Part of the incident response efforts are to understand and assess exactly what was done during an attack or compromise. Systems need to be scrutinized by a variety of forensic tools and in-depth investigations so that organizations can understand the depths of a compromise and the impact that compromise may have to information assets. Based on the scenario described (just before the guided exercise):  a. Create an incident response report using concepts from the guided exercise and the previous labs. The report should be no more than 3 pages, and should include:     i. Executive Summary (for non-technical decision-makers) • Answer specifics such as:           a. What was the attackers IP address?           b. How did attacker know which accounts to try?           c. Was root compromised?           d. How do we get more information on the File Manager app?     ii. Detection and Analysis (of the incident and events)           • Identify what, how, who, where, and when.           • Provide evidence (screenshots).     iii. Recovery • Provide recommendations            a. How can they prevent this in the future?            b. Should they notify customers and/or stakeholders?                        • Create a clear and concise timeline of the major events.      iv. Lessons Learned (from the company’s perspective)

Write a 2 – 4 page paper on “A day in your life and influence of modern Knowledge Management tools”. What kind of a day you are experiencing with and without various automated/digitized tools and devices (i.e., gadgets, wearables, etc.,)?
