Maths Mean, Median, Mode

 Write a blog post and explain what mean, median, mode 

MEAN - Is found  by adding all of the numbers together and dividing by the numbers of items in the set 

Identify - 10 + 10 + 20 + 40 + 70 / 5 = 30 

Who invented Mean?

The Belgian statistician Quetelet (1796-1874), famous as the inventor of l'homme moyen, the average man, was one of the first scientists to use the mean as tyhe representative value for an aspect of a population.

Mode: The mode is the number that occurs most often in a data set. To find the mode or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

Who Invented Mode?

Early use of the statistical concept of the mode was by English mathematician Karl Pearson (1857-1936) in 1895 

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Example: The median of 4, 1, and 7 is 4 because when the numbers are put in order (1 , 4, 7) , the number 4 is in the middle.

Who invented Median?

An early use in English of the statistical concept of median was Francis Galton's (1822-1911)

Shirley from Shaun the Sheep is an eating machine with a particular fondness for pizza. She's so big that she often get stuck and needs the other sheep to push, pull, or even slingshot her to safety.

Timmy He may be baby of the flock, but timmy is often at the center of things. It's good thing his mum is always there to keep him safe from other bad things.

Maths

Whereas the basic formula for the area of a rectangular shape is length x width, the basic formula for volume is length x weight x height. how you refer to the different dimensions does not change the calculation. the important thing is that the three dimensions are multiplied together. you can multiply in which ever order you like as it won't change the answer.
