Mean And Mode

 

 Mean and Mode

These 3 "M"s are three different subparts of the term 'average'. Average is calculated in many fields apart from maths as well, data science, economics and even statistics. There are three different ways of calculating average.

Mean

The most common way to calculate average is the mean. To find the mean, we use 2 steps only!








Let us take another larger sample set of data and do a worked example.

2,4,4,4,5,5,7,9.

These are our numbers and we have to calculate the mean.

1.) 2+4+4+4+5+5+7+9= 40

2.) There are 8 different numbers here. The mean equals 40 divided by 8 which is 5!


Mode

Mode is the simplest of all! All you have to do is identify which number repeats itself the most, if there is more than one number that repeats itself the same number of times, there simply is no mode.

So, taking the same sample set of data: 2,4,4,4,5,5,7,9.

The mode here will be 4 as it is being repeated thrice which is the highest number of times.


Questions:


 Find the mean and mode of the following:


1. 3.4.6.5,4,4,5,6,7,2


Answer: mean=4.6 and mode=4


2. 2,2,3,4,5,6,8,8,5,9


Answer: mean= 5.2 and mode= no mode

Solving Quadratic Equations ┃Middle Term Splitting

Image
  Middle Term Splitting Apart from plugging in the coefficients in the formula which solves quadratic equations, there are simpler ways of solving quadratic equations, without the use of calculators! The method described here is known as mid-term splitting.  Benefits: This method requires much less calculation and effort. It is solved in a quicker and cleaner method. Drawbacks:  Unlike the quadratic formula, the middle term splitting method only works in certain cases.  How does it work: a x²  + bx + c This method will only work if there are two numbers that add up to 'b' and have a product of 'a*c' What we do is we write the equation in another form and factorise it into two parts which equal zero. The examples below will explain better! Here, 6 and -5 are the two numbers needed. They are the set of numbers which add up to the origibal 'b' whoch was 1, and form a product of -30( a*c)! After that the equation was just factorised. Since this would equal to zero, ...

Finding the Areas of shapes in graphs

Image
  In a graph, there are numerous points which join to form various polygons. These polygons may be irregular in shape, with any number of sides. The area of these polygons can be found using different methods! If we have a regular polygon, we can use that polygon's formula to find the area. So if we have a hexagon, we can just use the formula :                                              a^2(3√3)/2 This is the formula to find the area of a regular hexagon. 'a' represents the length of a side. There is a different formula for different regular polygons.  The side length of a polygon can be found using the distance formula, where we calculate the distance between two points. But, what if the polygons are not regular? If they have different side lengths and different angles on each side? The formula generally used here is commonly known as the sh...

The Fibonacci Sequence

Image
  The Fibonacci When one of  "the most talented Western mathematicians of the Middle Ages", Leonardo Bonnaci, created the Fibonacci sequence, it became widely popular and since then, it has held its value as one of the  most famous mathematical concepts to ever exist amongst learners. It has impacted the world immensely, its influence ranging from finance and coding theories to even the shape of a simple flower! The Sequence: In the Fibonacci, each term is made up of the sum of its previous two terms.  N= (N-1) + (N-2) where 'N' is the term number. The  Fibonacci  sequence goes as follows: 0,1,1,2,3,5,8,13,21,34,55..... For example, lets take the 7th term which is 8. This implies that in our case N=7. The 2 terms before it, the 5th and 6th terms are 3 and 5  respectively , which add up to 8.  The next term would be the sum of 34 and 55, so the 12th term is 89!  The sequence goes on till   infinity . Applications in real life: T...
