Here is a set of data . 2 . 4 1 . 6 3 . 2 0 . 3 1 . 5 1 ) Calculate the mean . b ) Each piece of data is increased by 10 . Calculate the new mean . C ) FAH Each new piece of data is now doubled . Calculate the new mean .

a) Calculate the mean

The mean is calculated by adding up all of the terms in the data set and dividing that sum by the number of terms in the data set.

2 + 41 + 63 + 20 + 3 + 1 + 5 = 135

135 / 7 = 19.2857

mean = 19.2857 (please round to where you need)

b) Find the new mean

If each data value is increased by 10, that means that the mean is increased by 10. The mean is a non-resistant value, which means that it can be pulled in one way or another by outliers in a data set. And when a number is added to every term in the data set, the mean will also take on that number.

new mean = 29.2857

c) If each data value is doubled, that means the mean will also be doubled. As I said previously, the mean is a non-resistant measure. So if all the data values change in some way, then the mean will change in that same way.

new mean = 38.5714

Hope this helps! :)

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
