What is the value of doing this assignment? You’ll
practice your problem solving skill by identifying foundational
statistical concepts and explaining how data-driven decision making can
help inform real world problems. This will provide you with a solid
foundation that will help you to not only be successful in this course,
but to learn to make smarter, data-driven decisions in your personal and
professional life.

Your goal for this assignment is to:
Practice your problem solving skill by answering questions about
statistical concepts and the benefits and uses of data-driven decision
making.

Steps

STEP 1: Answer the questions below in a Word document.

1.
Explain the difference between descriptive and inferential statistical
methods and give an example of how each could help you draw a conclusion
in the real world.

2. You would like to determine whether eating
before bed influences your sleep patterns. Describe the steps you would
take to conduct a statistical study on this topic.

• What is your hypothesis on this issue?
• What type of data will you be looking for?
• What methods would you use to gather information?
• How would the results of the data influence decisions you might make about eating and sleeping?

3.
A company that sells tea and coffee claims that drinking two cups of
green tea daily has been shown to increase mood and well-being. This
claim is based on surveys asking customers to rate their mood on a scale
of 1–10 after days they drink/do not drink different types of tea.
Based on this information, answer the following questions:

• How would we know if this data is valid and reliable?
• What questions would you ask to find out more about the quality of the data?
• Why is it important to gather and report valid and reliable data?

4.
Identify two examples of real world problems that you have observed in
your personal, academic, or professional life that could benefit from
data driven solutions. Explain how you would use data/statistics and the
steps you would take to analyze each problem. You may also choose
topics below (or examples from the weekly content) to help support your
response:

• Crime reduction and trends

5. How does
analyzing data on these real world problems aid in problem solving and
drawing conclusions? Be sure to note the value and benefits of
data-driven decision making.

The assessment will be 500words long. Please see the questions shown in the screenshot. => only do Q10****
I will send you all info after hired, eg PPTs, student access etc. Please send a draft in 12hrs-1 day time

I need support with this Mathematics question so I can learn better.

Discuss why the concept of whole numbers important to people in everyday life? How do you use them in your daily life?

Rewrite a fraction, of your choosing, into a decimal. Discuss a situation in which you would need a decimal instead of its fraction equivalent.

There are many formulas used in Geometry.  Choose a formula and apply it to a real life situation.  Explain how the formula made performing the task much more simple.

Can you help me understand this Mathematics question?

Discuss a time you would need to use a ratio, proportion, or a percent.  Have you had to use either in your life recently?

Choose 3 problems that you have worked on since Assignment 2 and write up your solutions. The handouts we have used since Assignment 2 include the following:

The Harry Potter Problem, Adopting a Different Point of View, Solving a Simpler Analogous Problem, the Tower of Hanoi, Extreme Cases, and Making a Drawing.

You cannot use the problems which I did in class (the problems on the front of each strategy handout). Choose 3 problems from different handouts. Do not choose 3 of the easiest problems; choose at least 2 problems that require some work to solve. Remember, part of being able to solve problems is being able to communicate your solutions to others. For each problem, indicate where the problem came from (Ex – Extreme Cases problem #4) and write up a solution using complete sentences and proper English. Please use diagrams, charts, pictures and/or whatever else will help you explain your solution. You do not have to type it up, but it must be neat. Each problem is worth 4 points and the following scale will be used to score each problem.

4 pts: An appropriate strategy was implemented and explained. The reader can follow the solution through each step to the correct solution.

3 pts: Solution has one of the following characteristics:

2 pts: Solution has one of the following characteristics:

1 pt: Solution has one of the following characteristics:

0 pts: Solution is blank or contains no new information. No apparent understanding of the problem.

Here are the problems you need to fully solve in depth:

Extreme Cases problem #5:

5.In a drawer there are 8 blue socks, 6 green socks and 12 black socks. What is the smallest number of socks that must be taken from the drawer without looking at the socks to be certain of having 2 socks of the same color?

Making a drawing #7:

7. A jeweler makes silver earrings from silver blanks. Each blank makes 1 earring. The shavings left over from 6 blanks are then melted down and recast to form another blank. The jeweler orders 36 blanks to fill an order. How many earrings can be made from the 36 blanks?

Different POV #6:

6.If x+y=1 and x/y=1, what is the value of xy?

Overview: Prepare a PowerPoint poster that demonstrates your mastery of the concepts we learned this semester. This assignment assesses the following learning objectives.

• Provide experience in calculating simple statistics by hand and using available software packages
• Provide students with an understanding of which statistics are appropriate for a particular empirical problem

• Perform and present statistical analysis in a format that is consistent with professional standards

I have provided two data sets in this module as SPSS files. I did not identify the level of measurement. This is part of your assessment.

Data: There is one data set available to use beyond the 2018 GSS posted in this module.

This is a SPSS data set created by Dr. Chaires in Criminal Justice. The unit of analysis is police stops. You will need to look at the variable view to get an idea exactly what information is included in this data.

Instructions: Prepare a document in a poster format using PowerPoint. This document must include material form Chapters 1, 2, 3, 4, 7, 8, 9,10, 12, 13 and 14.

1. Start with one or two hypotheses
2. Use a table that identifies the variables and their level of measurement
3. Prepare at least one bar or pie chart
4. Prepare a table of means and standard deviations for all interval-ratio variables
5. Construct confidence intervals around means and proportions in the table of means and standard deviations.
6. Perform one difference of means test and present the results using a bar chart and the proof of statistical significance or lack of such
7. Present one cross-tabulation with a Chi-Square test of significance and describe the strength of the relationship
8. Present a scatter plot and a correlation coefficient –talk about the strength, significance, and direction of the relationship
9. Write one short paragraph that links your hypotheses to your analyses

Deliverable: A one-page poster that includes all the information described the rubric.

All tutors provide: high quality help, quick responsive communication, original explanations and answers with any outside resources cited.

I am sending you sample questions. I will post them to you at 9 am California time. There are six questions in total, and you have two hours to complete.
