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)
