Monitorare le risposte ai lead

La tua azienda usa un software di vendita per tenere traccia dei nuovi lead commerciali. Li organizza in una coda così chiunque può fare follow-up quando ha un po’ di tempo libero. Poiché il numero di risposte ai lead è un conteggio su un periodo di tempo, questo scenario corrisponde a una distribuzione di Poisson. In media, Amir risponde a 4 lead al giorno. In questo esercizio calcolerai le probabilità che Amir risponda a diversi numeri di lead.

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.
