In statistics, a confidence interval (CI) is a type of interval estimate which we compute using the statistics of the observed data. The interval has an associated confidence level that, loosely speaking, quantifies the level of confidence that the value Read more…
Suppose you have taken the data for heights and weights of students in class and you want to figure out the correlation between heights and weights of students. The relation between these two parameters is defined mathematically by one of Read more…
Types of Distributions Bernoulli and Binomial distribution A Bernoulli random variable has two possible outcomes: 0 or 1. A binomial distribution is the sum of independent and identically distributed Bernoulli random variables. So, for example, say I have a coin, Read more…
Populations and Samples The main difference between a population and a sample has to do with how observations are assigned to the data set Population Includes all of the elements from a set of data. Sample Consists of one or Read more…
Random Variables The term random variable is not very descriptive. A better term is measurement function.Consider tossing a fair six-sided die. There are only six outcomes possible, Ω = {1, 2, 3, 4, 5, 6} As we know, if the Read more…
As software developers, we try to tend to work with a lot of different technologies. We also face and solve a lot of technical challenges as part of our daily work. So what could be some of the reasons for Read more…
Dynamic typing Majority of people have a single problem with a python feature and drumrolls it’s Ducktyping. In short “If it walks like a duck and it quacks like a duck, then it must be a duck”. I agree that Read more…
Iris dataset is one of the most easiest and straightforward datasets to use. In Iris dataset, we can represent dataset as a matrix in the following format. Petal length Petal Width Sepal length Sepal width Flower-1 Flower-2 : Flower-n However, Read more…
Measures of central tendency To represent a quick summary of data we use several mathematical methods. These methods usually try to determine where the center of the dataset lie. There are three mathematical measures and they all have their own unique Read more…
Using the right Graphs are very important for representing the right type of data.We can say Data in statistics is of the following types For reading the details on all the different data types read here. https://towardsdatascience.com/data-types-in-statistics-347e152e8bee For Read more…
