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()
# Threshold for maths best score
Best_maths_score = 800 *0.8
# filtering the schools with the best maths score
Best_schools_in_maths = schools[schools["average_math"] >= Best_maths_score]
print(Best_schools_in_maths)
#saving the result into pandas dataframe and sorting by average math
best_math_schools = Best_schools_in_maths[['school_name', 'average_math']].sort_values(by = 'average_math', ascending = False)
print(best_math_schools)
#Determing the top 10 performing schools based on the combine sat score
schools["total_SAT"] = schools['average_math'] + schools["average_reading"] + schools["average_writing"]
# sorting it by total SAT
top_10_schools = schools.sort_values('total_SAT', ascending = False).head(10)[["school_name", "total_SAT"]]
print(top_10_schools)
#Gething the borough stats and roundong the the results to 2 decimal place
brorough_stats = schools.groupby("borough")['total_SAT'].agg(num_schools = "count", average_SAT = "mean", std_SAT = "std").round(2)
#Finding the borough with the largest standard deviation
largest_std_dev = brorough_stats.sort_values(by ='std_SAT', ascending = False).head(1).reset_index()
#printing the results
print(largest_std_dev)
