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()
# which nyc school has the best math results
best_math_schools = schools[schools['average_math'] >= 640][['school_name', 'average_math']].sort_values('average_math', ascending = False)
# 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 = schools[['school_name', 'total_SAT']]
top_10_schools = top_10_schools.sort_values('total_SAT', ascending = False).head(10)
#Which single borough has the largest standard deviation in the combined SAT score
boroughs = schools.groupby('borough')['total_SAT'].agg(['count', 'mean','std']).round(2)
value = boroughs['std'].max()
largest_std_dev = boroughs[boroughs['std'] == value]
largest_std_dev = largest_std_dev.rename(columns = {"count":"num_schools","mean":"average_SAT","std":"std_SAT"})
largest_std_dev.reset_index(inplace = True)
