Statistics in Education Policy
教育政策统计代写 This assignment will demonstrate how to use data to conduct policy analyses using a dataset from the Programme for International Student Assessment
This assignment will demonstrate how to use data to conduct policy analyses using a dataset from the Programme for International Student Assessment (PISA) conducted by the Organization for Economic Co-operation and Development (OECD). Using the 2018 dataset, you will answer the questions below and prepare a brief report of your findings. The report should be no more than 3 pages (excluding ouput) using 12 point font, 1.5 spacing. Please include your output with your brief.
Your memo should address: 教育政策统计代写
1.A brief description the data from each country (who is sampled? How are they sampled?)
2.An overview of the kinds of questions that are asked in the dataset.
3.A summary of key findings, including point estimates and confidence intervals
4.A brief discussion of how the findings could be used to improve educational outcomes in these countries.
You are being asked to compare the science or math results in two countries, one of which is the United States and the other is one of your choosing.
Conduct analyses that answer the following questions: 教育政策统计代写
How many observations are there from each country?
Using either math or science scores, what is the mean test score in each country? What is the standard deviation? What are the confidence intervals?
a. Run a ttest to see if these difference are statistically significant
Using the variables urban and public analyze differences between the two countries?
a. What percentage of students in each country attend public school?
b. What percentage attend urban schools?
c. Run a ttest on public (urban) to see if these inter-country differences are statistically significant
Using either public or urban, what do you hypothesize is the relationship between them and test scores between the two country? For example,
a. Looking only at public schools in the two countries is there a statistically significant difference between the countries on test scores? or
b. Looking only at urban schools is there a statistically significant difference between the countries on test scores?
c. Do the results support your hypothesis?
d. If you feel you can do it, what are the differences between urban public schools and test scores and the two countries?
