This is why you rarely see bats hanging in an attic in the winter-it is just too cold for survival.

We believe that the bats move around and adjust their position based upon the temperature.
The mean of a set of numbers is their average. You find the average of a set of numbers by adding them up and dividing by the number of numbers you have. So, the mean of 3,4,6,9, and 3 is: 3 + 4 + 6 + 9 + 3 25 ----------------- = -- = 5 5 5.
What does 'mean' mean in math terms? The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numberâ¦s. To find the median, your numbers have to be listed in numerical order, so you may have to rewrite your list first.
