Proyecto de Investigación
El Proyecto de investigación tiene como propósito aplicar los conocimientos adquiridos en el curso de Introducción a la Estadística.Preparar un cuestionario para recopilar unos datos (no menos de 30 datos, pero no más de 50 datos) para determinar el perfil de los estudiantes de EDP University o perfil de las personas que visitan tu iglesia o el perfil de un grupo de personas de tu interés. El cuestionario debe contener el nombre, edad, estado civil, peso, estatura, pueblo de residencia. Preparar una tabla de distribución de frecuencia con cinco clases donde vas a presentar la distribución de edad del grupo de personas escogidas. Recuerda que tu tabla debe contener las columnas de: fronteras, límites, puntos medios, frecuencias absolutas, frecuencias acumuladas, frecuencias absolutas relativas y acumuladas relativas.Dibujar un polígono de frecuencias y un histograma para presentar los datos de la tabla de distribución de frecuencias de la parte anterior.Usando los datos de la tabla de distribución de frecuencias, calcular: Media, Moda, Mediana. Primer Cuartil, Tercer Cuartil, Percentil 15, Percentil 85, Rango, Varianza, Desviación Estándar, Coeficiente Asimetría y Coeficiente Curtosis.Usando la tabla de distribución de frecuencias, las gráficas realizadas y las medidas de tendencia central y variación: Establece cinco conclusiones de los datos presentados.Usando los datos recopilados en el cuestionario, dibujar una gráfica circular para presentar los resultados de: estado civil y pueblo residencia. Debes trazar una gráfica para cada una de esas dos variables.Usando los datos recopilados en el cuestionario, dibujar una gráfica de tallo y hoja para presentar los resultados de: peso y estatura.

Statistic using Excel spread sheet/T1-T84 calculator.
The Excel spread sheet and pdf is for Experience 2 Application only.EXPERIENCE 3 ASSISGNMENT Suppose you are representing the employees at a large corporation during contract negotiations. You have a list of the salaries of all the employees at the corporation (The salaries include the many lower level employees and the few high paid management employees) and you plan to find a measure of center (e.g. mean, median, or mode).a. Which measure or center would you use to represent the employees in an effort to support your claim that the average salary of lower level employees is much lower than the national average (for lower level employees) and thus should be increased?meanmodemedianb. Why is this the better choice?Suppose you wish to invest money safely and are trying to decide between stock options in two companies. The average rates of return are the same for both companies but, one company has a much larger standard deviation of its rates of return. a. Which company should you invest in?The company with the smaller standard deviationThe company with the larger standard deviationb. Why is this the better choice? Describe the shape of the distribution for the following and justify your answer:a. The distance people travel to work on a typical day - The horizontal axis is the distance traveled in a person's daily commute. The vertical axis is frequency (number of people with that distance for their daily commute). Shape of distribution:skewed leftuniformskewed rightsymmetricJustification:b. Number of hours of sleep for each night of the week (weekdays only) - The horizontal axis is the day of the week (Monday to Friday) and the vertical axis is the amount of sleep in hours for that night. Shape of distribution:symmetricuniformskewed leftskewed rightJustification:c. Age of first heart attack - The horizontal axis is age. The vertical axis is frequency (number of people who had their first heart attack at that age). The population is people in the US who have had at least one heart attack. Shape of distribution:uniformsymmetricskewed leftskewed rightJustification:d. Scores on the Graduate Requirement Exam - This is a standardized test for people entering graduate school. The horizontal axis would be the person's total score. The vertical axis would be frequency (number of people with that score). The population would be all GRE test takers for a given year. Shape of distribution:symmetricskewed rightuniformskewed leftJustification:EXPERIENCE 2 APPLICATIONYou must use spreadsheet software (e.g. Excel) for this problem. 1. For each state and Washington DC, the percentage of people without health insurance was determined. Given the data set (The file is located in the main Experience folder) create the following using spreadsheet software. Refer to the model/methodology for the desired format. Make sure to use 5-20 classes with a "nice" class width when creating the distribution tables. Make sure to label axes in both graphs. a. Grouped frequency distribution (table) b. Grouped relative frequency distribution (table) c. frequency histogram (graph) d. relative frequency histogram (graph) Submit the completed spreadsheet as a .xls or .xlsx file. 2. A survey of 50 college students was conducted to determine how much weekly income they earned from employment. Given the data set in Applications folder for this experience complete the following. Refer to the model/methodology for the desired format. a. Find the 5 number summary of the data set. Min= Q1= Median= Q3= Max= b. Create a box-plot for the data set using software (Choices include: The boxplot generator linked in the resources area, spreadsheet software, TI-84 (take a picture of your calculator), other software or websites.) Upload your finished file below. Question 2 Part 6 of 9Choose File No file chosen c. Identify any outliers. List the individual numbers that are outliers for this data set. If there are multiple outliers, separate them by commas. d. Give a possible explanation as to why the individual (or individuals) from part c might have a number (or numbers) that are so high (or so low). e. Interpret yourself as a percentile in the data set. First estimate your weekly income from employment (If you are not employed then use 0). Then find the percentile (see book for the formula) for your income using the sample data. Then interpret the percentile using the definition and writing a complete sentence.

regression model
Review Warner’s Chapter 12 and Chapter 2 of the Wagner course text and the media program found in this week’s Learning Resources and consider the use of dummy variables.Create a research question using the General Social Survey dataset that can be answered by multiple regression. Using the SPSS software, choose a categorical variable to dummy code as one of your predictor variables.Estimate a multiple regression model that answers your research question. Post your response to the following:What is your research question?Interpret the coefficients for the model, specifically commenting on the dummy variable.Run diagnostics for the regression model. Does the model meet all of the assumptions? Be sure and comment on what assumptions were not met and the possible implications. Is there any possible remedy for one the assumption violations?

University of the Cumberlands Inferential Statistics in Decision Making Problem
Assignment:After reiewing the weekly readings and powerpoints, please complete the following:1. Describe one specific example in which a regression/Pearson Product moment correlation could be used to help make an informed decision. Please write in complete sentences. (10 points)2. Make a table that contains data that would be used to perform an analysis. Use your answer from #1 as the basis for your table. YOU DO NOT HAVE TO COLLECT DATA FROM AN OUTSIDE SOURCE. Make up the data that would make sense in the situation that you described in #1. (15 points)3. Run the analysis in JASP, Excel, or another program and record/upload your results. (10 points)4. Explain what decision you would make based on the results of the analysis that you performed. (15 points)Example:1. A coach wanted to know if the number of hours of practice per week shooting free throws improved the players skill in shooting free throws over the 8 week basketball season.2.WeekHours of practiceNumber of free throws made (out of 100 shots)1117255633294118455596338786482273. The value of R is 0.9606. The P-Value is .000148. The result is significant at p < .05.4. As a coach, I see that the data shows a strong correlation between the number of hours of practice and the number of free throws made. Therefore, I would encourage my players to practice free throws as much as possible. The data shows a strong positive correlation.
