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.

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.
