What are z-scores? Z-scores in statistics describe the relationship between a value and the mean of the data that is being observed. For example, if the z-score of a value is 1, that will mean the value is 1 standard deviation away from the mean of the data being...

What is the Central Limit Theorem? As per the Central Limit Theorem, if we take random samples of sufficiently large sample size, then the sampling distribution of the sample means will approach a normal distribution. And this will hold true even if the population is...

What is the five-number summary of a dataset? The five-number summary of a dataset consists of the following: The minimum number of the dataset The maximum number of the dataset The median of the dataset Quartile 1 of the dataset Quartile 3 of the dataset What is the...

What are quartiles? Let’s say we have a dataset. If we sort the dataset in ascending order, then quartiles divide the dataset into four equal parts. Q0 is the smallest number in the dataset and is called quartile 0. Q2 is the median of the dataset and is called...

Let’s say we are given a list of numbers. We want to shuffle the list. We can do so easily in Python using the shuffle() function from the random module. from random import seed from random import shuffle seed(1) data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] shuffle(data)...
