In this post, I am sharing some information that I learned in my Math 11 foundation class surrounding the applications of statistics.

In many given problems it is important to find the mean, median, range, and mode.

To find the mean: you take add of the numbers in the data, divide this by how many numbers there are to then find the average. the mean is the average between all of the numbers in that set of data.

To find the mode: You look at the data and find the number that appears the most.

To find the median: You put all the numbers in the grouping from smallest to largest and you find the number that has the middle value. the number needs to be directly center if there is an odd number of data or average the two in the middle if it is an even.

To find the range: take the largest number in the set and subtract the smallest.

Standard deviation:

To find the standard deviation, first find the mean of the set, (instructions above) for each number in the set subtract the mean and then square it. Take the new numbers to use the steps above to find the mean, finally, square root this number and you will have your standard deviation product.
