Analysis of Variance and its Variations
In statistics, when trying to compare samples, our first thought is to perform a student’s t-test. It compares the means of two samples (or a sample and population) relative to the standard error of…

Understanding Standard Deviation, Confidence Intervals, and Variance in Machine Learning
Standard deviation is a statistical measure of how spread out a set of data is from its mean or average value. It is a measure of the amount of variation or dispersion of a set of data points.In machi...

Using Standard Deviation in Python
As this article mentioned, with Standard Deviation you can get a handle on whether your data are close to the average or they are spread out over a wide range. For example, if an employer wants to…

Standard Deviation vs. Standard Error
Standard deviation measures the dispersion(variability) of the data in relation to the mean. In simple terms, the closest to zero the standard deviation is the more close to the mean the values in…

A Standard Error
I’m currently reading a best-selling book on probability as applied to everyday life, The Drunkard’s Walk: How Randomness Rules our Lives, by Leonard Mlodinow. It eloquently traces the history of…

Understanding Mean, Variance, and Standard Deviation with Python
Statistics plays a fundamental role in data analysis, and three key statistical measures are mean, variance, and standard deviation. In this article, we’ll explain what these terms mean and how to cal...

When Variance and Standard Deviation Fail to Explain Variability!
We all know the definition of variance — it helps us understand how dispersed the data points are, around the mean. If the data points are far off from the mean, we have larger curves than if the…

A visual interpretation of the standard deviation
One of the most central concepts in statistics is the concept of standard deviation and its relationship to all other statistical quantities such as the variance and the mean. Students in…

Variance: Sample vs. Population
In statistics and machine learning, when we talk about population, we mean the entire universe of possible values of a stochastic variable. If you know the population is always viable to compute the…

What is the variance in that metric?
Analysts often look at trends over time to get a feel for the level of noise in a metric, but too often noise in the measurement is not represented in the data that is used to make decisions…

Why do we use the standard deviation?
It feels like knowledge has advanced, and is continuing to advance, so quickly that in order to keep up there is no time at school to explain how and why things are the way they are. For me, standard…...

Bootstrapping the Standard Deviation
Bootstrapping is a resampling method that allows us to infer statistics about a population from a sample. It is also easy to perform and understand, which makes it so darn cool. Practitioners who use…...

Why does variance matter? 🤔
Hypothesis testing in statistics is a way for you to test the results of a survey or experiment to see if you have meaningful results. You’re basically testing whether your results are valid by…
