Review the Learning Resources and the media programs related to t tests. For additional support, review the Skill Builder: Research Design and Statistical Design and the Skill Builder: Hypothesis Testing for Independent Samples t-test, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane. Also, review the t test scenarios found in this week’s Learning Resources and consider the three different approaches of t tests: Independent sample t test Paired sample t test One sample t test Based on each of the three research scenarios provided, open the High School Longitudinal Study dataset or the Afrobarometer dataset from this week’s Learning Resources using SPSS software, then choose and run the appropriate t test. Once you perform your t test analyses, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document. For this Assignment: Write a 2 pages of analysis of your t test results for each research scenario and include the SPSS syntax and output.  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 X1SES. Do not forget to evaluate if the t test assumptions are met, justify the selection of type of t test, and report the effect size. Based on your results, provide an explanation of what the implications of social change might be. Use proper APA format, citations, and referencing for your analysis, research questions, and output. By Day 7 Submit Assignment: Testing Hypothesis for a Mean.

Make one research paper on how does sex and age affect music preference( what genre is the favorite) This is an IB math internal assessment in the level of math AI SL in highschool .. I want a good paper. 1st requirement is to read an example of a math internal assesment, I will help and link things to read before like an example and a general structure. I will link also all the data needed.  2nd You should make an investigation by doing some tests like a chi squared test or t-test with many diagrams and the box and whisker plot. You will probably have to make these tests by first grouping the data into different groups of genres like hipop pop and others . 3rd you should be prepared to make at least one draft before the final version, I will just give you feedback and areas that are lacking

The file attached is a sample of what the essay should look like, I am taking MATH SL (standard level) IB, application and interpretations meaning the essay isn’t only going to be coloration but a bit difficult than that by adding topics such as Box plot, Spearman’s Correlation, Regression Line etc. A survey should be conducted as well

ANSWER QUESTION  MUST PROVIDE SOURCES AND COMPLETE THE ATTACHED HOMEWORK The professor teaching a large introductory class gives a final exam that has alternate forms, A, B, and C. A student taking the exam using Form B is upset because she claims that Form B is much harder than Forms A and C. Discuss how percentile point data might be useful to determine if the student is correct. PSY-520 Graduate Statistics Topic 1 – Descriptive Statistics Project   Directions: Use the following information to complete the questions below. While APA format is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.   A researcher was interested in the anxiety present in students just prior to the midterm exam. The researcher used an anxiety self-quiz to gauge the student’s anxiety. The score for 30 students are given here.  69 99 91 66 70 98 70 53 40 58 61 66 94 77 70 56 88 85 86 40 84 86 54 48 86 43 78 53 79 89   1.     Construct a frequency table with class, frequency, relative percent, and cumulative percent that has 6 classes to describe the distribution of the data in SPSS.    2.     Use the frequency table to construct a histogram in SPSS.      3.     Use SPSS to calculate the numerical descriptive statistics mean, median, standard deviation, and variance of the anxiety scores.    4.  The following table shows distributions of bachelor’s degrees earned in 2011–2012 for selected fields of study by all male graduates and by all female graduates. Bachelors Degrees Earned in 2011-2012 by selected field of study and gender ( in 1000) Major                           Males                Females Business                       190.0                   176.7 Social Science               90.6                      87.9 Education                       21.8                   84.0 Health Science               24.9                     138.6 Psychology                        25.4                      83.6 Engineering                     81.3                       17.3 Life Science                       39.5                      56.3 Fine arts                              37.2                  58.6 Communication                33.5                     55.2 Computer science                38.8                 8.6 English                                  17.0                36.8                                  TOTAL 600.0            803.6 (A) How many female psychology majors graduated in 2011–2012? (B) Since the total numbers of male and female graduates are fairly different—600.0 thousand and 803.6 thousand—it is helpful to convert first to relative frequencies before making comparisons between male and female graduates. Then, inspect these relative frequencies and note what appear to be the most conspicuous differences between male and female graduates. (C) Would it be meaningful to cumulate the frequencies in either of these frequency distributions? (D) Using just one graph, construct bar graphs for all male graduates and for all female graduates. Hint: Alternate shaded and unshaded bars for males and females, respectively.

This assignment has two parts, which will be submitted in one document.For this task, you will calculate the mean, median, and mode for a fictitious data set. These data represent the results of a fictitious study, which investigates whether a new drug (Drug A) is more effective than a placebo (i.e., an inactive substance) in the treatment of depression. The researcher is also interested in whether the effects of the drug varies by age so participants between the ages of 18-39 years were recruited (the younger adult group), and participants between the ages of 60-80 years were recruited (the older adult group). Participants were randomly assigned to either the placebo group or to the drug group (Drug A). All participants were first screened to ensure they met the criteria for depression. After 2 months of taking either the placebo or Drug A, participants returned to the lab and completed a measure of depressive symptomology called the Beck Depression Inventory-II (BDI-II).Part 1:For the first part of this assignment, create a table showing the mean, median, and mode for each participant group and each drug condition on the score for the BDI-II. The data for each participant are contained in the “Participant Data” worksheet in the Data1 File. You may use Excel or you can calculate these values by hand. Your table should look like the following:  I will upload the table latYou must have the “Data Analysis” add-in installed. Directions for this installation are provided in the “Data Analysis in Excel 2016” file located under your weekly resources. These instructions will also work for Excel 2010. This document also describes how to calculate basic descriptive statistics using Excel.Part 2:For this part of the assignment, create a bar chart in Excel. You will need the “Summary Data for Graph” worksheet from the Data 1 file. Remember, the bar chart shows the means for each condition rather than individual participant data, and the data in this worksheet have been organized accordingly.For the steps regarding how to create the bar graph, review the steps in “Creating a Bar Graph in Excel 2016” or “Creating a Bar Graph in Excel 2010,” located under your weekly resources. These instructions should also work with other versions of Excel.You should copy and paste the graph you create into a Word document, along with your table showing the mean, median, and mode.Length:1-2 pagesYour graph and table should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards.

Please adhere strictly to using the APA format for this assignment.StatCrunch web-based software to be used where necessary.It costs only 14 USD and you can create a student account in a few minutes.Please read all the instructions carefully in the document attached!
