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...
# Add as many cells as you like...
best_math_schools = schools[schools['average_math']>=.8*(800)][['school_name','average_math']].sort_values(by='average_math',ascending=False)
best_math_schools
schools#top 10 performing schools based on combined SAT scores
schools['total_SAT'] = schools['average_math']+schools['average_reading']+schools['average_writing']
top_10_schools = schools.sort_values(by='total_SAT', ascending=False)[['school_name','total_SAT']].head(10)
top_10_schools#Largest_std_dev dataframe creation
# Need: borough, num_schools, average_SAT, std_SAT
#Which single borough has the largest standard deviation in the combined SAT Score
#We need to create a dataframe with rows for each borough, total number of schools, average SAT #score, and standard deviation of the SAT scores.
#So the key is we are doing this grouped by borough
boroughs = schools.groupby("borough")["total_SAT"].agg(["count","mean","std"]).round(2)
largest_std_dev = boroughs[boroughs['std']==boroughs['std'].max()]
largest_std_dev = largest_std_dev.rename(columns={"count":"num_schools","mean":"average_SAT","std":"std_SAT"})
