26,30,45,43,26,14,28,33,56,29,what is the mean of the data set

Answer 1

"Mean" just means "average". Add all the numbers up and divide by how many numbers there are.

26+30+45+43+26+14+28+33+56+29 = 330
Since there are 10 numbers that were added, divide 330 by 10 to get 33.
33 is the mean of the data.
