Whoa there, Nellie!!
No one wants to do your homework for you.
Let's see your attempts at solutions.
Find the mean, median interval, mode, spread, and average spread.
Do not round any of your answers.
15, 11, 7, 15, 10, 7, 10, 10, 10, 7, 10, 12, 11, 11, 8, 12, 8, 12, 12, 6
mean = ?
median = ?
mode = ?
spread = ?
average spread = ?
As for the median and the mode, I suggest you go back and review the definition of each of these statistics in your classnotes and/or textbook. Then, if you still need help, please be specific about what you don't understand.
