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 schools are best in math?
best_math_schools = schools[schools['average_math'] >=640][['school_name', 'average_math']].sort_values('average_math', ascending = False)
# Calculate total_SAT per school
schools['total_SAT'] = schools['average_math'] + schools['average_reading'] + schools['average_writing']
# Who are the top 10 performing schools?
top_10_schools = schools.sort_values('total_SAT', ascending = False)[['school_name', 'total_SAT']].head(10)
# Which NYC borough has the highest standard deviation for total_SAT?
boroughs = schools.groupby('borough')['total_SAT'].agg(['count', 'mean', 'std']).round(2)
# Filter for max std and make borough a column
largest_std_dev = boroughs[boroughs['std'] == boroughs['std'].max()]
# Rename the columns for clarity
largest_std_dev = largest_std_dev.rename(columns={'count': 'num_schools', 'mean': 'average_SAT', 'std': 'std_SAT'})
# Move borough from index to column
largest_std_dev.reset_index(inplace=True)
