Potansiyel yanıtlarını izleme

Şirketin yeni satış potansiyellerini takip etmek için bir satış yazılımı kullanıyor. Bu yazılım, potansiyelleri bir kuyruğa yerleştiriyor; böylece biri boş vakit bulduğunda takip edebiliyor. Bir zaman aralığında sayılabilir bir sonuç olan potansiyel yanıtı sayısı, Poisson dağılımına karşılık gelir. Amir, günde ortalama 4 potansiyele yanıt veriyor. Bu egzersizde, Amir’in farklı sayıda potansiyele yanıt verme olasılıklarını hesaplayacaksın.

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.

Exercise 1: What is statistics?Exercise 2: Descriptive and inferential statistics Exercise 3: Data type classification Exercise 4: Measures of center Exercise 5: Mean and median Exercise 6: Mean vs. median Exercise 7: Measures of spread Exercise 8: Variance and standard deviation Exercise 9: Quartiles, quantiles, and quintiles Exercise 10: Finding outliers using IQR

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.
