I have to do calculations based off an assignment for my psychology statistics class. And complete a calculations template. The calculations have to be in the excel sheet under the data set to show how I got the calculations.
Collection and Data Analysis: " Overview You will collect and analyze the dataset as described in your proposal. Collected data will be analyzed using the techniques learned in the content portion of the laboratory as appropriate for the data type, and proposed relationship between explanatory and response variables. Instructions Please include in this document any incomplete analysis that you attempted on your data, even if you found it to not support or inconclusive for your report. Use this to show the data tracking that you may have attempted." Collection and Analysis: Students will collect and analyze their dataset as described by their proposal. Collected data will be analyzed using the techniques learned in the content portion of the laboratory as appropriate for their data type, and proposed relationship between explanatory and response variables. All statistical testing will be submitted, including any tests that do not support your hypothesis or lead you to additional testing. Use text boxes to show your thought process. For example, if you run a histogram on a piece of data use a text box to note its distributions. This is the same process used in all class assignments. Final Report: " Instructions The Final Report should present the findings of the analysis as well as the methodology for collecting the data. The report should demonstrate quantitative communication skills, proficiency in mathematical reasoning, and the correct interpretation of the results. A document that I recently found posted on the internet talks about Statistical Research, and while this class is not looking for a document quite that detailed, it does provide some extra information for those wondering what they might be able to do and how they might be able to do it. Again I repeat this is not the complexity that is expected but is some good information that might help some of you. This book is located at https://www.airweb.org/docs/default-source/documents-for-pages/reports-and-publications/case-study-applications-of-statistics-in-ir.pdf?sfvrsn=b4b4739_2Links to an external site. Please note: This is to be a Scientific/Statistical Report and as such it does require an Abstract, not including this will result in a 10-point deduction on your submission." Final Report: A written report of the project serves as the culmination of the project and will be submitted on the last class day. It will present the findings of the analysis as well as the methodology for collecting the data. Students will demonstrate their quantitative communication skills, proficiency in mathematical reasoning, and their correct interpretation of their results. The final report will contain all proper supporting evidence and explanations from the collection and analysis of the data. Frequently Asked Questions about the Final Paper How long should my paper be? The paper should be as long as it needs to be to properly convey the statistical results of your data. The Results, Conclusions, and Reflections should be addressed in all papers. One of these sections will be lengthy depending on the data. How do I know I am completing the assignment correctly? Ask yourself if you have shown in your paper that you understand and are able to represent statistical language shown by the data collection. Which format should I use? It is up to you to decide what format you want to use. Whatever you decide to use, you will need to stick with the same format for the entire paper. If you are not sure what format to use, you will find information at the Purdue OWLLinks to an external site.. How much research should I do? If you need to find some statistical information that is not included in your data, you will need to do some research but this is not a research paper. Research may not be necessary and is not a requirement. What might my paper look like? While an example Table of contents is provided in the attached Example Word doc some case study summaries can be found both in the data links and through a web search for Statistical Case studies a collection is available for review at https://epubs.siam.org/doi/epdf/10.1137/1.9780898719741.ch2Links to an external site. while this is a book for purchase you can still see the example of a summary and a start of an introduction that might help you get an understanding of some of the final projects researchers might submit. Please note these are final research documents and you are not being asked for this level of detail bit might help you see what you might want to consider when you start to consider your proposal.
Most likely there's going to be one question for each Chapter in Stats listed below. You helped me last time so I am confident that the other chapters shouldn't be an issue with you. Intro to Data, Data Collection, Descriptive Stats, Probability, Discrete Probability Distribution, Confidence Intervals for One Population, Hypothesis Test for one Population, Hypothesis Tests & Confidence Intervals for two Populations and Correlation and Regression. Time limit is 2hrs. Should be around 15-25 questions. Similar to last time.
You will perform the calculations for three problems using data in the attached spreadsheet containing Data Set 7. Please perform the calculations in the spreadsheet. Upload all of your answers, including your analysis and interpretation, in a Word document. Please also upload your Excel spreadsheet to show your calculations 19. The data in tab 19 (Delivery data) in DS7 show the distribution of women recently delivered of a newborn infant at two hospitals. The data show the numbers of women delivered by caesarean section (and non-caesarean delivery) for each hospital. Using these data, do the following: Assuming an alpha of 0.05, test the hypothesis of independence between the prevalence of caesarean section deliveries and hospital (use both the CHISQ.TEST and the CHISQ.DIST.RT functions in Excel). Report the results of your statistical test and provide an interpretation of these results. (6 points) Create a table displaying the conditional probabilities and describe any relationships suggested by these probabilities. Be sure to report the prevalence of C-section delivery for each hospital. (2 points) Repeat the test of independence from part 19.a but assuming that an alpha of 0.1 indicates statistical significance and report the results. (1 point) Interpret your results from part 19.a but assuming now an alpha of 0.01. (I.e., report whether you accept or reject the null hypothesis under these conditions.) Report your interpretation in the Word document for this problem set. (1 point) 20. Assume the data in tab 20. (Clinic wait time) of DS7 represent random samples of 90 records from each of four health centers. These data display the distribution of patients by health center and whether the time each spent waiting to be seen was excessive. Perform the following: Compute the prevalence of excessive waiting time (i.e., compute the conditional probabilities), describe the conditional probabilities and any relationship suggested by these probabilities. Include the conditional probability table and the prevalence figures in your report. (2 points). Assume that alpha is 0.05, test the hypothesis that waiting time does not differ by health center (use both the CHISQ.TEST and CHISQ.DIST.RT functions in Excel). Report the results of the statistical tests and your interpretation of these. (6 points) Calculate the critical value of the chi-square statistic for alpha = 0.05 and the appropriate degrees of freedom for these data; repeat for alpha = 0.001. Report the results of your calculations in your Word document for this problem. (1 point) Interpret your results from part 20.b assuming alpha for statistical significance is 0.001. Report your interpretation in the Word document for this problem set. (1 point) 21. Assume the data in tab 21. (Prenatal care) of DS7 represent a properly collected representative sample of women delivering infants at your hospital. The data show the number of women in each of three categories of socio-economic status (SES) according to the category of healthcare professional attending her delivery. Consider the proposition that any apparent differences in source of prenatal care according to the socio-economic status of the mother are due to chance alone. What are the null and alternate hypotheses implied by this statement? (2 points) Combine the data from the Generalist column and the Specialist column into a single column (any physician). This will produce a new data table with three rows for SES (High, Middle, Low) and two columns for source of care (Midwife, Physician). Using this new data table, test the hypothesis that source of care (Midwife v. Physician) is independent of SES and report your results and interpretation. (6 points) 3. Compute the conditional probabilities for this new data set and describe the results in a single sentence. (2 points)
Control charts are monitoring schemes, widely used in operations and manufacturing environments, to determine when a process is "in-control" and in the presence of only common-cause variation. Give an example of an application of control charts in an industrial, operations, or manufacturing setting that is different from those supplied in the overview. Discuss and share this information with your classmates. In responding to your peers' posts, select responses that use a control chart that is different from your own. Is the process in control or out of control? Would the process be in control if Western Electric rules are considered? Explain your reasoning. Finally, consider how control charts can be applied to the final project case study. Support your initial posts and response posts with scholarly sources cited in APA style.
Create your Joint Probability Table Create a joint probability table of the two variables associated with the letter of your last name. Be sure your values are proportions/percentages are rounded to two decimal places rather than counts. Create a Joint Probability Table for international students and number of languages spoken/known. Take a screenshot of each graph/table. Save as an image so that you can upload them to your discussion post. Draw the Normal distribution for student height Use the given parameters below to draw a normal distribution model for heights of BA275 students in our class with your gender (for non-binary students please feel free to choose either gender distribution). Include the mean and +/-1, 2, 3 standard deviations away from the mean. Female Students Height in Inches: ?= 64.8 inches and ?= 3.0 inches Non-Female Students Height in Inches: ?= 70.5 inches and ?= 3.1 inches Ways to draw the Normal Distribution: By hand, on paper. Use your phone to take an image for your post. Using a stylus and tablet. Take a screenshot for your post. Explan the analysis Use the "Original Post - Outline & Prompts" to Create Your Original Post Use the title "Week 2 Data Analysis" Use the same headers as listed below (e.g., "Joint and Conditional Probability") in your post. Answer each question/prompt in the bulleted list below each heading in your post. For the math related questions, please show your work or excel functions you used to find your answers, Use the following questions to guide your reflection: You are welcome to copy and paste these prompts into your post along with your responses to them.

Question 1 Using the skills you learned in weeks 1 and 2 evaluate a set of statistics. An Excel spreadsheet is attached including 30 data sets representing the height and weight of 14 year old boys. The first column is the height in inches and the second the weight in pounds. Choose one data set that has not already been selected (include the number of the data set in your title to make this easier to do). Calculate the mean, median and mode of the weights in the data set. You can either do this by hand or see the video below to show you how to do this using the tools in Excel. Then, explain what these numbers mean. Are they the same? Why are they different? Then, construct a scatter plot. From the insert menu select scatter or the chart that says scatter and then select the chart at the top left on the dropdown Click on one of the points Select Add Trendline (Note you may need to add Trendline and then click on the line to format Trendline) The default radio button is linear, keep it checked What are your observations from the scatter plot? Does it appear that there is a correlation between the height and weight of 14 yr old boys. Note: this data is made up, so do you think this is accurate? Do you think given real data that there would be a greater amount of correlation or less? If you have a different version of excel then you may want to search to see how to form a trendline. These instructions work with Office 365 and Office 2010. Attach your excel worksheet with your scatter plot For the title of your post use your last name and the data set that you selected (Example: Smith - Data Set #51). Be sure to comment on at least 2 classmates. You could discuss other times that this visualization would be useful? Or what other visualizations could be useful in this scenario? How do you choose?
