Question

What is the mean of the following data set?
{4, 5, 2, 4, 9, 7, 5, 5, 2, 8, }

Answer 1

If I'm not mistaken you add the numbers up, then you divide it by the amount of numbers there. 4 + 5 + 2 + 4 + 9 + 7 + 5 + 5 + 2 + 8 = 51
51 / the amount of numbers there (10) = 5.1

Hope this helps :)
