Ortalama ve medyanı hesaplama

Bu bölümde, nu3 tarafından hazırlanan 2018 Food Carbon Footprint Index kaynağındaki food_consumption veri kümesiyle çalışacaksın. food_consumption veri kümesi, her bir country ve yiyecek kategorisi için kişi başına yıllık tüketilen yiyecek miktarını kilogram cinsinden (consumption) ve bunun kilogram karbondioksit, yani CO₂ olarak ölçülen karbon ayak izini (co2_emissions) içerir.

Bu egzersizde, pandas ve numpy becerilerini kullanarak ABD ve Belçika'daki yiyecek tüketimini karşılaştırmak için merkez ölçülerini hesaplayacaksın.

pandas senin için pd takma adıyla içe aktarıldı ve food_consumption önceden yüklendi.

Summary statistics gives you the tools you need to boil down massive datasets to reveal the highlights. In this chapter, you'll explore summary statistics including mean, median, and standard deviation, and learn how to accurately interpret them. You'll also develop your critical thinking skills, allowing you to choose the best summary statistics for your data.

In this chapter, you'll learn how to generate random samples and measure chance using probability. You'll work with real-world sales data to calculate the probability of a salesperson being successful. Finally, you’ll use the binomial distribution to model events with binary outcomes.

It’s time to explore one of the most important probability distributions in statistics, normal distribution. You’ll create histograms to plot normal distributions and gain an understanding of the central limit theorem, before expanding your knowledge of statistical functions by adding the Poisson, exponential, and t-distributions to your repertoire.

In this chapter, you'll learn how to quantify the strength of a linear relationship between two variables, and explore how confounding variables can affect the relationship between two other variables. You'll also see how a study’s design can influence its results, change how the data should be analyzed, and potentially affect the reliability of your conclusions.
