How do you find the sum of squared deviations in a set of numbers?
It would be useful to know what the deviations were from.
What is the median if there is only 2 numbers showing?
Technically, you cannot find a median if you have only two numbers, so it would be more reasonable to use an average instead.
How do you find percentage in a histogram?
To find the percentage in a histogram you need to add the numbers together and divide how many numbers you have. For example, if you have four customers that spend $20, $25, $30, and $35, you would add the totals together and divide by four.
How do you find a mean of a set of numbers?
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.
What if you have two modes in a set of numbers?
For example...If you had a set of numbers like this -4, 6, 8, 1, 3, 4, 4, 4, 1, 7, 1, 6, 1,... and you were asked to find the mode (the most frequently occurring value in a set of data)then you would find that numbers 1 and 4 would BOTH be the mode because they both occur the most, yet they occur the same amount of times each.So in this case you would simply end up with two different modes.For this reason using the mode to find the average of a set of data is not always as reliable as using the median or the mean because with them you can have only one answer per data set.How to find the Median :For example these are YOUR numbers.4,6,8,1,3,4,4,4,1,7,1,6,11) Find your two middle numbers.2) Are they even ? ( if so add them (......) then what ever you get your answer by divide your answer by TWO.)The two MIDDLE numbers are 4 AND 4.3) I ADD 4 + 4.( = 8 )4) 8 Divided by TWO.( = 4 )THAT'S HOW YOU GET YOU MEADIAN !!!!HOPEFULLY YOU UNDERSTAND * GOOD LUCK*For example here is a set of numbers 3,4,2,4,3,3,4,7,4,3,4you would go with four because it has more numbers occurring than three.I would just like to add that it is helpful to put the numbers in order from least to greatest.
