Question

"What is the sample median of the student-teacher ratio (STR) in the 'MASchools' dataset from the 'AER' package? The dataset contains data on test performance, school characteristics, and student demographic backgrounds for school districts in Massachusetts. To retrieve the data, you can use the command:

data("MASchools", package = "AER")
Once you have the dataset, find and report the sample median of the student-teacher ratio (STR) to two decimal places.

Answer 1

To find the sample median of the student-teacher ratio from the 'MASchools' dataset in R, load the dataset and calculate the median of the STR column.

Step-by-step explanation:

The student is asking for the sample median of the student-teacher ratio (STR) from the 'MASchools' dataset, which can be found in the 'AER' package in R. To calculate this median, one would first need to load the dataset using the command data("MASchools", package = "AER") and then compute the median of the STR column. The calculation process would involve sorting the STR values and finding the middle number, or the average of the two middle numbers if there is an even number of observations.
