Every year, American high school students take SATs, which are standardized tests intended to measure literacy, numeracy, and writing skills. There are three sections - reading, math, and writing, each with a maximum score of 800 points. These tests are extremely important for students and colleges, as they play a pivotal role in the admissions process.
Analyzing the performance of schools is important for a variety of stakeholders, including policy and education professionals, researchers, government, and even parents considering which school their children should attend.
You have been provided with a dataset called schools.csv, which is previewed below.
You have been tasked with answering three key questions about New York City (NYC) public school SAT performance.
# Re-run this cell
import pandas as pd
# Read in the data
schools = pd.read_csv("schools.csv")
# Preview the data
schools.head()
# Start coding here...
# Which NYC schools have the best math results?
best_math = schools[schools["average_math"] > 800 * 0.80].sort_values("average_math", ascending=False)
best_math_schools = best_math[["school_name", "average_math"]].reset_index(drop=True)
print(best_math_schools)
# What are the top 10 performing schools based on the combined SAT scores?
schools["total_SAT"] = schools["average_math"] + schools["average_reading"] + schools["average_writing"]
top_10_schools_sort = schools.sort_values("total_SAT", ascending=False).head(10)
top_10_schools = top_10_schools_sort[["school_name", "total_SAT"]]
print(top_10_schools)
# Which single borough has the largest standard deviation in the combined SAT score?
# Fixing the error by using transform instead of value_counts
schools["num_schools"] = schools.groupby("borough")["school_name"].transform('count')
schools["average_SAT"] = schools.groupby("borough")["total_SAT"].transform('mean').round(2)
schools["std_SAT"] = schools.groupby("borough")["total_SAT"].transform('std').round(2)
largest_std_dev_sort = schools[["borough","num_schools","average_SAT","std_SAT"]].drop_duplicates()
largest_std_dev = largest_std_dev_sort.sort_values("std_SAT", ascending=False).head(1)
print(largest_std_dev)schools.head()
