This article will explain the concept of locally weighted regression, which is a type of linear regression. We use linear regression in cases where the dataset is linearly correlated and is not suitable for non-linear datasets. For non-linear datasets, a concept of LOWESS is introduced.
The Geometric figures are anyfigure that is formed in space that meets certain characteristics. For its study many factors are considered, the number of sides it has, the length of those sides, its internal angles, and that it is closed (that is, that all its sides are connected by a vertex).
Math Lesson 1: What is it and how to calculate LCM and GCD.
The Five Letter Opposite Word Game and Puzzle is easy to make from a single sheet of paper in about 30 minutes with only a pencil, pen, and ruler. It is a slider type puzzle that involves moving letter pieces from top to bottom. Easy to make, hard to solve. Originally designed in 1957.
Few people would have predicted the mathematical controversy that would follow the first time the 'three door problem' was played on the quiz show, Let's Make A Deal. The game is easy to play, but the implications in terms of probability theory were controversial and divisive.
An enthusiastic teacher goes overboard to discuss the famous Pancake Problem, bringing in sorting algorithms and recursion techniques in an analysis of stacks of different sized pancakes. Intuitive conclusions are drawn regarding the number of pancake tosses a hapless chef needs to make.
The area of a flat shape can be estimated by dividing it into unit squares and counting their number. Pick's Theorem provides a method to find the exact area of a polygon drawn on a dotted grid. We look at how the Theorem works and establish a proof using Euler's formula.
Shaking hands is one of the most common activities we do. But have you considered just how many handshakes you would have to make in a room full of people? We will delve into the mathematics of handshaking and combinatorial analysis.
This mathematical investigation generally aimed to develop a mathematical formula to calculate the number of regions formed by connecting the points on the perimeter of a circle. Specifically, this investigation aimed to observe some patterns that will help the investigator develop a conjecture.
Virtually every processed item, be it animal, vegetable or mineral, has associated with it a signature known as a barcode. This article examines two standard footprints that provide substantial information about a product; EAN-13 and ISBN.
Mathematical language is a system used to express, communicate and convey mathematical information. It is distinct and unique from the usual language that people are used to and is used to communicate abstract and logical ideas. Mathematical language is characterized by abstraction symbols and rule.
Fibonacci Sequence is popularized in Europe by Leonardo of Pisa, famously known as Leonardo Fibonacci. The nth term of a Fibonacci sequence is found by adding up the two Fibonacci numbers before it. But how can we find the nth term of a Fibonacci sequence without it's two preceding terms?
There are many things parents can do to assist their child to cope with the rigors of mathematics. This article provides specific examples and general advice to parents who can act as mentors.
A relation or function can be represented in five ways–ordered pairs, table of values, mapping diagram, graph, and rule or equation. This article will give you the discussion on these 5 representations of relations or functions.
Graph theory is a very important field of mathematics. It has a lot of real world applications. The basics are not very difficult.
This article establishes mathematics' relation with beautiful components of nature. It focusses on the technicalities associated with it and explains the reason behind it. It's an answer to the curiosity that arises when we admire the beauty of these creations.
Geometric shapes are always good to look at but sometimes difficult to memorize with regards to what are the properties they have in common, what makes them different and so on. So, here we are to discuss some tips which makes learning the properties of quadrilaterals easy.
Spearman Rank Correlation and Pearson Correlation can be both used to identify the relationship between two sets of data. This a brief comparison between the two measures of correlation and there are examples provided to explain how to solve them.
Coincidence or the presence of a certain third, unseen factor? Is this how a conspiracy theory is born? An illusory correlation or in Latin, 'um hoc ergo propter hoc', "with this, therefore because of this," also called the false cause.
Prepare for your engineering board exam by learning the different calculator techniques in Mathematics. Master the calculator techniques and surely, you'll do good in your engineering board exam.
Number series is a part of the reasoning in mathematics. It's a very interesting and good exercise for the brain. In most competitive exams it is asked. If you know the tricks you can solve it quickly. The article mainly focuses on three sequences— A.P, G.P., & H.P
Step into any classroom you'll see the difference from the class of twenty years ago. Have the Interactive whiteboards trapped students of today in a class of digital resources that has not kept pace
I was worried about the performance of my children in mathematics over other required subjects. However, after, I learn about Singapore math program. They started solving problems with ease.
