Aggregating and Summarizing Government Data
Aggregating and summarizing data are essential tasks in government analysis, allowing you to extract actionable insights from large datasets. These techniques help you answer questions such as total expenditures across departments, average service usage per region, or the distribution of resources over time. By combining and summarizing data, you can identify trends, spot anomalies, and make informed policy recommendations. For example, calculating the total population served by various regions or determining the average income level across communities can provide crucial context for resource allocation and program evaluation.
1234567891011121314# Summing up total population across multiple regions using a for loop regions = [ {"name": "North District", "population": 120000}, {"name": "East District", "population": 95000}, {"name": "South District", "population": 78000}, {"name": "West District", "population": 110000} ] total_population = 0 for region in regions: total_population += region["population"] print("Total population across all regions:", total_population)
When analyzing government data, you frequently rely on summary statistics to interpret and communicate findings. Common summary statistics include the mean (average), median (middle value), minimum (lowest value), and maximum (highest value). These metrics are vital for understanding the central tendency and spread of your data. For instance, the mean can indicate the average income in a community, while the median is useful when the data contains outliers or is skewed. The minimum and maximum values help you quickly identify the range and potential anomalies, such as the region with the lowest or highest service usage. Using these statistics, you can provide clear, evidence-based insights for policy development and evaluation.

1. Why is it important to compute summary statistics when analyzing government data?
2. Which function would you use to find the maximum value in a list of numbers in Python?
3. What summary statistic would best represent the typical value in a highly skewed dataset?

Can you explain how the median function works in this example?
What other summary statistics can I calculate with this data?
How can I modify the code to find the region with the lowest median income?
Чудово!
