e For Part 2, you need to present your screen time data set in table format or in a spreadsheet format. In addition, you need to show the mean and standard deviation formulas, and provide a brief but accurate explanation of each formula. Next, you need to SHOW the calculation work and actually calculate the mean and standard deviation of your data set. Part 2 has a 6 Step procedure shown below in the Instructions section, which should be followed. For each Step. make sure to SHOW all calculations work required to complete the given Step, and submit this in your work file for grading. Part 2 Conduct your own statistical data analysis project, the Screen Time Project. Complete the following 6 Steps SHOWING all steps and calculations work with explanation where needed. e Step 1-Survey 10 friends and family. Ask each of them how much screen time they have had either for the last 7 days (each day) or the average for the last 7 weeks (each week). So your screen time survey data set should contain a total of 70 values. Using this data, create a table to collect this data or use a Google form (how to find screen time on android and iPhone). (Include your handmade data table or spreadsheet with your assignment submission). e Step 2 - Read this article: Sample vs Population Standard Deviation. Which formula will you use for your sample and why? Include this information with your standard deviation calculations work and in your Final Report (Step 6). e Step 3 - Calculate the mean and standard deviation. Write out and explain each formula. You can do all the calculations yourself or use Google Sheets. Use Google Sheets to calculate the standard deviation. e Step 4 - Using this data and the z-score table what percent of young people spend over 10 hours a day looking at their phones? e Step 5 - Using the z-score table, based on your data, how much screen time would fall into the top 5%? How much would fall into the bottom 5%. Step 6 - Using the normal distribution tables, write a report based on your data. Summarize the above steps and include information about the ages and gender of the people surveyed. Do you think the data is the same for all age brackets? How could you find out? How many hours are within one standard deviation of the mean, and any other relevant information. Lastly, use your information to draw your own conclusions. Additional Helpful Hints & Tips When doing this Unit 8 Assignment make sure to show all your work. To get full credit for this assignment, you need to show and explain each step of what you computed. Write out each formula you use even though you may have used a statistical calculator or the spreadsheet to perform the operation. Before submitting your work for grading, always take the time to carefully review the instructions in this document and look at the Grading Rubric provided to make sure that you have completed all required tasks and to see how the assignment will be graded. Part 2 Data Presentation Part 2 Z-scores Part 2 Concluding Paragraph Survey includes 15 people with 7 data points. Data Is presented in an easy to read table. Includes, average and standard deviation Calculations for the all three z- score related guestions are clear and correct. The paragraph is well written and includes all the required detail. The student draws appropriate conclusions. More than half of the data was collected Information is missing in the table/spreadsheet Calculations for the all three z- score related questions are missing necessary steps and/or incorrect. The paragraph is coherent and lacks the details or elements required. Less than half of the data is collected Effort was made, but the important details are missing. Not correct but effort was made or not enough detail was shown Effort was made, but important elements are missingStep by Step Solution
