How to calculate Mean, Median and Mode
Mean
Add up all of the numbers then divide the total number amount of how many numbers there are
Median
Order all the numbers in numerical order then find the middle number in the list and thats the median. If there are two numbers in the middle add both the numbers together the divide by two.
Mode
To find the mode order the numbers then count how many of the same number there is. the number with that is the most often is the mode.
Who invented Mean, Median and Mode
Mean
The term is first found in the mid-1690s in the writings of Edmund Halley, and it has been used to summarize observations of a variable since the time of Galileo.
Median
An early use in English of the statistical concept of median was Francis Galtons observation that “the median … is the value which is exceeded by one-half of an infinitely large group, and which the other half falls short of”
Mode
An early use of the statistical concept of the mode was by English mathematician Karl Pearson in 1895 when he stated that “I have found it convenient to use the term mode for the abscissa corresponding to the ordinate of maximum frequency”
Give an example of a practical use use- where you would find it useful
For mean you can use it to fint the average of something for exaple sports often show player stats with averages. They would add up all the blocks he made every game then divide it of how many games and that would give him an average.
