Definition of Quartiles What are Quartiles? In statistics, Quartiles are values that divide your data into quarters. They aren’t shaped like pizza slices. Quartiles divide your data into 4 segments according to where the numbers fall on the number line. The 4 quarters that divide a data set into quartiles are: Lowest 25% of numbers. Next lowest
Mean is the average of the numbers. How to Find the Mean It is easy to calculate: add up all the numbers divide by how many numbers there are In other words it is the sum divided by the count Mean For Negative Numbers How to handle negative numbers? Adding a negative number is the
Geometry is one of mathematics’ branch. It has many shapes that one of them is plane geometry. In plane geometry, there is quadrilateral shape that has many kinds of it. One of them is trapezoid. In daily life, trapezoid can be found in handbag, bridges, and popcorn box in cinema. Definition of Trapezoid Trapezoid is
Sequence A Sequence is a set of things (usually numbers) that are in order. 1, 3, 5, 7, … Each number in the sequence is called a term (or sometimes “element” or “member”). Arithmetic Sequence In an Arithmetic Sequence, the difference between one term and the next is called a constant. In other words, we
There are 2 main temperature scales: Scale Detail °C the Celsius Scale (part of the Metric System, used in most other countries) °F the Fahrenheit Scale (used in the US) They both measure the same thing (temperature!), but use different numbers Typical Temperatures in Daily Life Description °C °F Moderate Oven 180 356 Water boils 100
Definitions of Matrix Matrix is numbers that are arranged into row and column. If there is more than one matrix called matrices. There is no rule about the number of row and column. The number of row and column is called dimensions. Notation of Matrix If there are a, b, c, d, e, f, … as
Degree can mean several things in mathematics: In Geometry a degree (°) is a way of measuring angles, In Algebra “Degree” is sometimes called “Order” Degree of a Polynomial A polynomial looks like this: 2×3 + 3×2 + x -1 The Degree (for a polynomial with one variable, like x) is the largest exponent of that variable. More
Definition The exponent of a number says how many times to use the number in a multiplication. In 42 the “2” says to use 4 twice in a multiplication, so 42 = 4 × 4 = 16 In words: 42 could be called “4 to the power 2” or “4 to the second power”, or simply “4
Definition SSS means “Side, Side, Side” When we know 3 sides of the triangle, we can find the missing angles. How To Solve SSS Triangle To solve SSS triangle: use The Law of Cosines to calculate one of the angles use The Law of Cosines to find another angle use angles of a triangle add
Cuboids are familiar objects you encounter in daily life numerous times. Cuboids are essentially boxes, formed exclusively from rectangles. These familiar shapes are also known as rectangular prisms. Definition of Cuboid The cube is a 3D structure which is formed when 6 identical squares bind to each other in an enclosed form. Remember all cubes
